Exaeretodon is an extinct genus of traversodontid cynodont which lived throughout what is now India and South America from the Ladinian stage to the Norian stage of the Triassic period some 235 to 205 million years ago. The naming of exaeretodon seems to have a bit of a complicated history with different specimens having been attributed to various genere such as Belesodon, Traversodon, Theropsis, Ischignathus with the later two genere now considered completely synoyomous with exarertodon. For example the type specimen consisting of a near complete skull was initially described as Belesodon argentines in Ángel Cabrera until with the help of José Bonaparte, they distinquished it as its own distinct genus. Today over 200 specimens have been recovered, some in remarkably good condition including a mother who was preserved pregnant with two calves. Four species are considered valid. E. argentinus from the the Ischigualasto Formation in the Ischigualasto-Villa Unión Basin of northwestern Argentina. E. major and E. riograndensis are from the Santa Maria Formation of the Paraná Basin in southeastern Brazil. And E. statisticae is from the Lower Maleri Formation of India. Reachign some 5 to 6ft (1.5 to 1.8m) in length and 130 to 190lbs (60 to 86kgs) in weight, exaeretodon was a fairly large low-slung creature. Despite its massive jaws and terrifying appearance, studies show its teeth were well developed to grind vegetation meaning that exaeretodon was likely a grazing herbivore. And was on of the most numerous herbivores of the middle and late Triassic southern pangea.

picking these 10 was very difficult there are too many triassic weirdos and I'm not even touching the sea right now

top 5 places in argentina? like, places you'd recommend to foreigners visiting your country? especially if they're not particularly famous

(hope that's not too intrusive for you, it's alright if you're not comfortable answering!)

what a great question, thank you! (it probably will end up being popular places, but let's be honest, they're popular for a reason and i want everyone to know about them!)

bariloche - i think the south of argentina is possibly the most beautiful spot on earth, and i absolutely adore bariloche. yes, there are other towns that are probably prettier (san martín de los andes, villa la angostura, all worthy of a visit), but i've been lucky enough to go to bariloche many times thanks to a friend with family there, so it's very special to me. some of the most spectacular vistas everywhere, lots of trekking to do, sailing excursions, and even action adventures las rafting and the like, it's such a perfect place for me (bonus for my most favorite place there, the tea house bellevue, obligatory stop there!). i've only really visited during summer (except for that one time with the school graduation trip, of course), but i'd love to see it in winter, it must be gorgeous!

(here are some pics of mine, this last one is the view from bellevue, it's so dreamy!)

glaciar perito moreno - ok, while we're still in patagonia, i might as well mention the perito moreno glacier, cause it's honestly jawdropping. to be there, in silence, looking at that massive wall of ice, it's humbling and awe-inspiring, i don't know how else to put it. and if you're lucky enough to see the ice breaking and falling, i can't imagine how that would feel like. of course, global warming is definitely troubling when it comes to natural wonders like this, but man, it's simply incredible. i've heard there are excursions to walk on the ice as well, that's a bit scary to me, but it must be one hell of an experience.

valle de la luna and talampaya - two national parks (the first one literally called "valley of the moon", but its real name is national park ischigualasto) they are...something else. the valle de la luna is possibly the most otherwordly place i've ever seen. it's this vastness of rock carved by the wind, the sun, the water for millions of years, truly looking like an alien landscape. you can literally see the evolution of the earth in its geological formations, and it's also really important for paleontological research. talampaya is right next door and it's breathtaking as well, reddish and strange and wonderful (first pics are the valley of the moon, the other two talampaya).

cataratas del iguazú - probably the most famous one (natural wonder of the world!) but like, for a goddamned reason! absolutely insane experience that i'd love to relive someday because i was very young when i went there. but yeah, standing there and seeing the intense, beautiful, dangerous force of nature that is those immense waterfalls, it's crazy. i mean, one of the sections of the waterfall is called garganta del diablo, devil's throat, so yeah, this shit is POWERFUL. i'd loveee to do one of those crazy boat trips that get close to the waterfalls, that seems insane lmao. also i think they did night trips to the garganta del diablo? that must be a religious experience!

ciudad de buenos aires - i mean of courseeee i'm gonna say buenos airessss that is my PLACE. and sure, you know how a lot of the times natives end up knowing a lot less about their city than the tourists that come visit? yeah, i'm probably not the best guide, but i could show you the places that TRULY matter, like the botanical gardes that i love to chill in, and the street i love to walk on especially when the jacarandá trees are in bloom, or the cemetery that we all love, or that vegan place with kinda mid food but a really cool, funky atmosphere, or that escape room i've been meaning to go to. what i'm trying to say is that buenos aires is my place in the world, and i could never, ever leave here. i carry it in my bones and in my blood (and for the argentines reading this, Y SI, puta...y porteña <3). no professional, touristy pics here, just some random shit from my camera roll.

Valley of the Moon, Argentina

Ischigualasto Provincial Park, also called Valle de la Luna (“Valley of the Moon” or “Moon Valley”), due to its otherworldly appearance, is a provincial protected area in the north-east of San Juan Province, north-western Argentina, limiting to the north with the Talampaya National Park, in La Rioja Province.

Both areas belong to the same geological formation, the Ischigualasto Formation (sometimes Ischigualasto-Talampaya Formation) Established on 3 November 1971, the park has an area of 60,370 ha (603.7 km2; 233.1 sq mi)

Side Note: Here's something else the eco freaks can spray paint. In life you are either a creator or a destroyer. Enviro-whackos are nothing but destroyers.

[mineralsrocksandfossiltalks]

Answer time! For a very long time, Eoraptor and Herrerasaurus were considered the oldest dinosaurs. They come from the Ischigualasto Formation in Argentina.

However, Nyasasaurus of Tanzania possibly comes from middle Triassic rocks which makes it older than these two.

Now, if you agree with research release this year, even Nyasasaurus might not be the oldest. It might be the silesaurid, Gamatavus who definitely comes from middle Triassic Brazilian rocks. Silesaurids were long thought to be a sister taxa to dinosaurs but very recent wok shows they might actually be early ornithischian dinosaurs. How cool is that?

However you look at it, all of these are very old avemetatarsalians!

Dinovember day 2: Herrerasaurus

All known specimens of Herrerasaurus were found in the Ischigualasto Formation of northwestern Argentina, which dates back to the late Triassic period. Herrerasaurus is one of the earliest known dinosaurs in the fossil record.

Source: Wikipedia

[i-draws-dinosaurs]

What's the earliest known *definitive* dinosaur?

Currently, that would be Staurikosaurus!

Staurikosauus is from the Lower Santa Maria Formation, and has been dated to 233.23 million years old, making in about 1.5 million years older than other very early dinosaurs like Eoraptor and Herrerasaurus from the Ischigualasto Formation!

However, if we want to delve into questionable dinosaurs, there's a genus named Nyasasaurus that is known from very fragmentary remains, and may or may not be a dinosaur!

Nyasasaurus is from the Manda Formation in Tanzania, which seems to have been roughly 235-240 million years old, although dating is a bit shaky with this one. If Nyasasaurus is really a dinosaur it would be the oldest known, but again we don't have enough of the skeleton to be sure! The Wikipedia reconstruction of it literally looks like this, to give you an idea of how uncertain its anatomy is:

Chiniquodon

(Image: Chiniquodon, a medium-sized, rather generic-looking protomammal with a short tail, depicted here with a covering of short hair. Image by @Stolpergeist)

Etymology: Tooth from Chiniquá, Brazil

First described by: von Huene, 1936

Classification: Biota, Archaea, Proteoarchaeota, Asgardarchaeota, Eukaryota, Neokaryota, Scotokaryota Opimoda, Podiata, Amorphea, Obazoa, Opisthokonta, Holozoa, Filozoa, Choanozoa, Animalia, Eumetazoa, Parahoxozoa, Bilateria, Nephrozoa, Deuterostomia, Chordata, Olfactores, Vertebrata, Craniata, Gnathostomata, Eugnathostomata, Osteichthyes, Sarcopterygii, Rhipidistia, Tetrapodomorpha, Eotetrapodiformes, Elpistostegalia, Stegocephalia, Tetrapoda, Reptiliomorpha, Amniota, Synapsida, Eupelycosauria, Sphenacodontia, Sphenacodontoidea, Therapsida, Eutherapsida, Neotherapsida, Theriodontia, Eutheriodontia, Cynodontia, Probainognathia, Chiniquodontoidea, Chiniquodontidae

Referred Species: C. theotonicus, C. brasilensis, C. kalanoro, C. sanjuanensis

Status: Extinct (sadly :( )

Time and place: Chiniquodon lived from the Ladinian to the Carnian of South America and Africa (including Madagascar), about 242-227 million years ago.

Physical Description: As a cynodont, Chiniquodon was a close relative of mammals, but it’s aberrant compared to most fossil mammal relatives in one key respect: It’s known from more than just teeth! You heard that right, Chiniquodon is known from several reasonably complete skulls, as well as some body fossils. Thus, we can actually have some discussion of its appearance and anatomy beyond the teeth!

Chiniquodon was a medium to large (for the time) cynodont, with a skull length up to 33cm/13in in length. This skull had wide zygomatic arches (attachment points for jaw muscles!), and a solid secondary palate (as in modern mammals). 

Its limbs and hips show that it was adapted to walk with its legs directly under the body, as in modern mammals. It had a fairly short tail. While we don’t have any direct evidence of its body covering, it’s likely that it had some hair, as has been inferred in other cynodonts. It got up to about the size of a medium dog.

…..But let’s be real, this is a mammal relative. We have to talk about teeth at some point.

Luckily for us, Chiniquodon has interesting teeth! Like, really interesting. Here’s a diagram of the skull of a typical chiniquodont:

(Image: A diagram of the skull of a typical chiquodont. It’s got very large canines. Illustration B shows its cheek teeth from the side (top) and from the top (bottom). Image from Abdala and Giannini, 2002.)

What is the significance of these teeth? I guess you’ll have to wait until the “diet” section to find that out!

Diet: Oh look, we’re here. What were we on? Oh, right! The significance of these teeth. I’m sure many of you are chomping at the bit to find out what they were eating, and are about to point to those huge canines as proof that they were ravenous carnivorous beasts. And you may be on the cusp of an incisive argument, but I’d like to remind you that large canines do not a carnivore make, and modern musk deer have large canines themselves. To truly understand what an animal is eating, we need to look at the teeth that we know it used to process food. In this case, those are the cheek teeth.

The cheek teeth of Chiniquodon are a particular shape of tooth called a carnassial. That carn- is the same carn- as in carnivore or carnival or chile con carne, and it means meat. That’s because it’s a shape of cheek tooth that is especially good at cutting meat, because they have very large cusps that shear past each other when the animal bites down. Carnassials are found in many modern carnivorans (including dogs and cats!), but the carnassials of Chiniquodon evolved completely independently from those of dogs or cats – an amazing example of convergent evolution.

Behaviour: As a terrestrial carnivore, Chiniquodon must have hunted at some time. It likely hunted small vertebrates, such as other synapsids or young dinosaurs, though it likely wouldn’t have turned down scavenging from a carcass or eating bugs when it was younger. It almost certainly laid eggs, which it may have laid in a burrow. It is not clear whether any parental care was present. 

Ecosystem: During the Triassic, all of the continents were combined into one, and this led to a very hot and dry climate over much of the Earth. Chiniquodon’s environment was no exception, and fossils of it are found in rocks interpreted to have been deposited by braided streams in an arid environment. With that said, some fossils of it are also found in rocks distributed during the Carnian Pluvial Event (aka That Time It Rained For Several Thousand Years; no relation to carnassials). These rocks contain the remains of animals like the early dinosaurs Eoraptor and Herrerasaurus, crocodile relatives like Gualosuchus, large dicynodonts like Ischigualastia, and other cynodonts like Probainognathus. 

Other: Chiniquodon, in our prehistoric hindsight, is positioned right around one of the most significant transitions in mammalian evolution. It records the condition of cynodonts at a pivotal point, when it and its relatives were only just evolving furry body coverings and specialised jaw joints, and it’s a crucial fossil in untangling how its close close relatives miniaturised, going from medium-sized animals to the tiny shrew-like creatures that became the ancestors of all mammals. Today, with our prehistoric hindsight, Chiniquodon represents a sideshoot off of the mammal line during a pivotal transition time – but in its brightest day, when it was scurrying about the floodplains of South America and Africa, it was merely another animal fighting for existence in the world of the Triassic.

A new and improved (?) version of my old Herrerasaurus ischigualastensis piece!

Herrerasaurus was one of the earliest dinosaurs. It lived during the Late Triassic (Carnian) period in northwestern Argentina. It was a lightly built bipedal carnivore with a long tail and a relatively small head. Its length is estimated at 3 to 6 meters (10 to 20 feet) and its hip height at more than 1.1 meters (3.3 ft).

Herrerasaurus has been classified as either an early theropod or an early saurischian, with many researchers treating it at least tentatively as the most primitive member of Theropoda.

The Ischigualasto Formation in northwestern Argentina was a volcanically active floodplain covered by forests, with a warm and humid climate. It was subject to seasonal variations including strong rainfalls. Vegetation consisted of ferns, horsetails, and giant conifers, which formed highland forests along the banks of rivers.

This is a speculative restoration based on the likelihood that proto-feathers were present in basal dinosaurs, and perhaps even a more ancestral animal, in light of the pycnofibers of pterosaurs.

[pleistocene-pride]

Eodromaeus is an extinct genus of probable basal theropod dinosaur which lived throughout what is now South America during the Carnian stage of the Triassic period some 232 to 228 mya. The first remains now known to be eodromaeus was a crushed but nearly complete articulated skeleton was recovered from the base of the Valle de la Luna Member of the Ischigualasto Formation by Argentinean paleontologist Ricardo N. Martinez and Earthwatch volunteer Jim Murphy in 1996. However both believed it to be a new species of eoraptor. It wouldn’t be until 2011 that an indepth review of the specimens would recognize that they warrented being classified as there own genus which was dubbed Eodromaeus meaning dawn runner in greek. With the specific name murphi honoring Jim Murphy. Today the remains of at least six eodromaeus specimens are known. Reaching around 3.9ft (1.2m) in length and 9.9 to 16lbs (4.5 to 7.1kgs) in weight, Eodromaeus was a small and lightly built dinosaur which had long hindlimbs making it well built for running. It had a low rectangular skull with slender lower jaw and a deep brain case. When originally described in 2011, Eodromaeus was regarded as the earliest member of Theropoda. This has been continousely supported by many subsequent studies; however there has been some that argue that Eodromaeus is rather a basal saurischian and possibly ancestral to theropods as a whole. What is known is that this small carnivorous dinosaur lived alongside and occasionally fed upon a variety of the strange and wondrous Triassic weirdos that called the Ischigualasto formation home.

Silesaurus opolensis

By José Carlos Cortés

Etymology: Silesian Reptile

First Described By: Dzik, 2003 

Classification: Dinosauromorpha, Dinosauriformes, Dracohors, Silesauridae, Sulcimentisauria  

Time and Place: Around 230 million years ago, in the Carnian of the Late Triassic

Silesaurus is known from the Drawno Beds Formation of Poland

Physical Description: Silesaurus was a very common almost-dinosaur - specifically, the titular member of the Silesaurids - from Poland in the middle of the Triassic period. It was a quadrupedal animal, about 2.3 meters long and small enough that it most likely would have been covered in fluff. Like other Silesaurids, it was long - with a long neck and a long tail, and long limbs easily reaching to the ground. Like other Silesaurids, it almost had its legs directly underneath its body - it didn’t seem to have an open acetabulum, but rather a partially open one, though Silesaurids are something of a confusing case on this regard. It had a small head, with a little beak in the front, and small sharp conical teeth. In addition, it had very large eyes, giving it distinctly good eyesight, as well as a decent sense of smell. As a quadruped, its front limbs were rather extended, while the hind limbs did a lot of the weight support. 

Diet: Interestingly enough, though for a long time it was thought that Silesaurus was an herbivore, recent fossil poop studies have indicated it was an insectivore - similar to living birds.

By Ripley Cook

Behavior: If Silesaurus really was an insectivore, it would have spent much of its time moving around in its environment, examining it closely for insects and pecking at the ground with its small beak for food. This pecking may have even looked a lot like that of living birds - the large eyes probably would have prevented the eyes from moving much, like in living birds, and as such Silesaurus would have had to bob its head in order to see. It  would have been very careful in its environment, making sure to look for food and avoid predatory dangers in its environment. It would probably have been social - corroborated by the fact that it was very common in its environment - and taken care of its young to some extent. As an Archosaur, it would have been warm blooded as well, and very active. 

Ecosystem: Silesaurus lived in a Mediterranean-esque scrub environment, with summer monsoon seasons and dry winters. The swampy coniferous forest and fernlands it lived in had a wide variety of animals, placing Silesaurus in a unique ecosystem of the Carnian age. This is actually quite important, given that the Carnian Pluvial Event - a minor mass extinction that helped to spur Dinosaurian evolution - occurred around the same time, leading to Silesaurus and its contemporaries being a snapshot of this change. A variety of invertebrates lived alongside this animal, giving it plenty of food, as well as Temnospondyls such as Metoposaurus and Cyclotosaurus, the Aetosaur Stagonolepis, the Phytosaur Parasuchus, the Rauisuchid Polonosuchus, the Sharovpterygid Ozimek, and probably some Tuataras and maybe even a Pterosaur. A small community, but a beautiful portrait of this time period, with its fair share of weirdos and precursors. And Silesaurus would have had a lot to look out for with Polonosuchus at just the right size to attack it. 

Other: Do not let Silesaurus’s weird similarities to birds fool you - it wasn’t an early bird, but a showcase of how bird-like traits kept popping up over and over again in the line of animals leading up to them. In fact, the evolution of such a specialized feeding system is notable in such an early member of the Ornithodirans. Silesaurids in general are extremely interesting because of their mixture of characters - similar to dinosaurs, but not quite there; with legs almost directly underneath the body, but other traits that match the later Ornithischians. The problem with Ornithischians - the bird-hipped dinosaurs - is that they have a bit of a ghost lineage, aka even though they should have showed up at the same time as Theropods and Sauropodomorphs, they don’t until the Early Jurassic. This isn’t as big of a gap as some other examples, but it is notable. Silesaurids have come out as Ornithischians just enough times in phylogenetic studies to bring it up as a question - are they almost-dinosaurs? The first bird-hips (without having bird-hips)? Something else entirely? More research is necessarily, but one thing is for sure - this group of weird dinosaurian experiments is one to keep an eye on, especially as we learn more and more about them.

I made a Staurikosaurus pricei artwork (paleoart?) because I couldn’t find any good art when I needed it. There are 2 versions of it: scaled and with a speculative integument. Cranium, manus and pes based on Herrerasaurus ischigualastensis. Due to being a rather small animal, with most probably a quite large head, I enlarged the eye opening slighty. Colours inspired by owls, lynx, bobcat and civets because I wanted some nice pattern, in case of forests.

Climate did not impact dinosaur abundance in the Triassic • Earth.com

New Post has been published on https://petnews2day.com/reptiles-news/climate-did-not-impact-dinosaur-abundance-in-the-triassic-earth-com/

Climate did not impact dinosaur abundance in the Triassic • Earth.com

During the time of dinosaurs in the Late Triassic, variations in the abundance and diversity of plant and vertebrate animal species cannot be causally related to the climate changes that occurred during that period. This is the conclusion of a new study led by the National Scientific and Technical Research Council in Argentina (CONICET) and the University of Utah in the United States.

By analyzing multiple independent lines of evidence drawn from sedimentology, clay mineralogy, and geochemistry, the researchers explored changes in paleoclimatic conditions, such as mean annual temperatures and precipitation, within the Ischigualasto Formation – a collection of fossil-rich sedimentary rocks deposited by rivers and streams during the late Triassic period (about 231 to 226 million years ago) in what are now the San Juan and La Rioja provinces in Northwestern Argentina. Although the scientists managed to identify a clear change from warmer and drier to more temperate and humid conditions, no concurrent major changes could be identified in the fossil record.

“We conclude that variations in the abundance and diversity of species, as recorded by their first and last appearances in the fossil record, are better explained by preservation and sampling biases than by changes in climate,” said study lead author Adriana Mancuso, a paleontologist at CONICET.

“What we see is that how many specimens collected from each interval of the sequence, and the chemical and physical characteristics that allow greater or lesser preservation of the remains of animals and plants, were significant factors. These two factors, collection and preservation, have more influence on the increase or decrease of abundance and diversity than the climate changes recorded.”    

However, Dr. Mancuso and her colleagues managed to identify a relationship between climatic variations and two groups of reptiles: the rhynchosaurs, a group of herbivorous early archosauromorphs, and pseudosuchians, a type of crocodilian-line archosaurs. “We did find that the abundance of rhynchosaurs and extinction of a few pseudosuchian species appear to coincide with a climate shift,” said study co-author Randall Irmis, a paleontologist at the University of Utah.

This study highlights the importance of an explicit framework for testing hypotheses about the correlation between the fossil record and climatic changes. “In addition to the contribution on the relationship of biotic and climatic events in the Ischigualasto Formation, the work provides a methodological framework to test climate-biota associations, highlighting the data gaps that must be filled, and makes new testable predictions that can be tested in future studies,” Dr. Mancuso concluded.

The study is published in the journal Frontiers in Earth Science.

This is the conclusion of a new study led by the u003ca href="http://www.conicet.gov.ar/"u003eNational Scientific and Technical Research Councilu003c/au003e in Argentina (CONICET) and the u003ca href="https://www.utah.edu/"u003eUniversity of Utahu003c/au003e in the United States.u003c/pu003ennnnu003cpu003eBy analyzing multiple independent lines of evidence drawn from sedimentology, clay mineralogy, and geochemistry, the researchers explored changes in paleoclimatic conditions, such as mean annual temperatures and precipitation, within the Ischigualasto Formation – a collection of fossil-rich sedimentary rocks deposited by rivers and streams during the late Triassic period (about 231 to 226 million years ago) in what are now the San Juan and La Rioja provinces in Northwestern Argentina. Although the scientists managed to identify a clear change from warmer and drier to more temperate and humid conditions, no concurrent major changes could be identified in the fossil record.u003c/pu003ennnnu003cpu003e“We conclude that variations in the abundance and diversity of species, as recorded by their first and last appearances in the fossil record, are better explained by preservation and sampling biases than by changes in climate,” said study lead author Adriana Mancuso, a paleontologist at CONICET.u003c/pu003eu003cdiv class="PrebidAdSlot_prebidIncontentSlot__2XOy7 PrebidAdSlot_desktopAd__HjuWa" data-reactroot=""u003eu003cdiv id="pb-slot-desktop-incontent-1-para-inj-0" class="pb-slot " data-parent-div-id="pb-slot-desktop-incontent-1" style="min-width:728px;min-height:90px"u003eu003c/divu003eu003cscriptu003en (function() n const observerConfig = n rootMargin: '1200px 0px 1200px 0px',n threshold: 0n n const observer = new IntersectionObserver(entries =u003e n entries.forEach(entry =u003e n if (entry u0026u0026n entry.isIntersecting u0026u0026n entry.intersectionRatio u003e 0) n );n , observerConfig);n const div = document.getElementById('pb-slot-desktop-incontent-1-para-inj-0');n if (div) n observer.observe(div);n n ());n u003c/scriptu003eu003c/divu003eu003cdiv class="PrebidAdSlot_prebidIncontentSlot__2XOy7 PrebidAdSlot_mobileAd__JpW4z" data-reactroot=""u003eu003cdiv id="pb-slot-mobile-incontent-1-para-inj-0" class="pb-slot " data-parent-div-id="pb-slot-mobile-incontent-1" style="min-width:300px;min-height:250px"u003eu003c/divu003eu003cscriptu003en (function() n const observerConfig = n rootMargin: '1200px 0px 1200px 0px',n threshold: 0n n const observer = new IntersectionObserver(entries =u003e n entries.forEach(entry =u003e n if (entry u0026u0026n entry.isIntersecting u0026u0026n entry.intersectionRatio u003e 0) // in viewn window.tude = window.tude n );n , observerConfig);n const div = document.getElementById('pb-slot-mobile-incontent-1-para-inj-0');n if (div) n observer.observe(div);n n ());n u003c/scriptu003eu003c/divu003ennnnu003cpu003e“What we see is that how many specimens collected from each interval of the sequence, and the chemical and physical characteristics that allow greater or lesser preservation of the remains of animals and plants, were significant factors. These two factors, collection and preservation, have more influence on the increase or decrease of abundance and diversity than the climate changes recorded.”u0026nbsp;u0026nbsp;u0026nbsp;u0026nbsp;u003c/pu003ennnnu003cpu003eHowever, Dr. Mancuso and her colleagues managed to identify a relationship between climatic variations and two groups of reptiles: the rhynchosaurs, a group of herbivorous early archosauromorphs, and pseudosuchians, a type of crocodilian-line archosaurs. “We did find that the abundance of rhynchosaurs and extinction of a few pseudosuchian species appear to coincide with a climate shift,” said study co-author Randall Irmis, a paleontologist at the University of Utah.u003c/pu003ennnnu003cpu003eThis study highlights the importance of an explicit framework for testing hypotheses about the correlation between the fossil record and climatic changes. “In addition to the contribution on the relationship of biotic and climatic events in the Ischigualasto Formation, the work provides a methodological framework to test climate-biota associations, highlighting the data gaps that must be filled, and makes new testable predictions that can be tested in future studies,” Dr. Mancuso concluded.u003c/pu003eu003cdiv class="PrebidAdSlot_prebidIncontentSlot__2XOy7 PrebidAdSlot_desktopAd__HjuWa"

Although the scientists managed to identify a clear change from warmer and drier to more temperate and humid conditions, no concurrent major changes could be identified in the fossil record.u003c/pu003enu003c!-- /wp:paragraph --u003ennu003c!-- wp:paragraph --u003enu003cpu003e“We conclude that variations in the abundance and diversity of species, as recorded by their first and last appearances in the fossil record, are better explained by preservation and sampling biases than by changes in climate,” said study lead author Adriana Mancuso, a paleontologist at CONICET.u003c/pu003enu003c!-- /wp:paragraph --u003ennu003c!-- wp:paragraph --u003enu003cpu003e“What we see is that how many specimens collected from each interval of the sequence, and the chemical and physical characteristics that allow greater or lesser preservation of the remains of animals and plants, were significant factors. These two factors, collection and preservation, have more influence on the increase or decrease of abundance and diversity than the climate changes recorded.”u0026nbsp;u0026nbsp;u0026nbsp;u0026nbsp;u003c/pu003enu003c!-- /wp:paragraph --u003ennu003c!-- wp:paragraph --u003enu003cpu003eHowever, Dr. Mancuso and her colleagues managed to identify a

find that the abundance of rhynchosaurs and extinction of a few pseudosuchian species appear to coincide with a climate shift,” said study co-author Randall Irmis, a paleontologist at the University

addiction to mobile devices, Dr. Nidhi Gupta – the founder of u003ca href="https://kapendocrine.com/"u003eKAP Pediatric Endocrinologyu003c/au003e in Franklin, Tennessee – has discovered that extensive screen time increases the prevalence of obesity, dyslipidemia, prediabetes, and type 2 diabetes. This study is an extension of Dr. Gupta’s previous research, in which she examined the role of mobile devices overuse in health care settings, and found that devices such as smartphones or tablets are often a source of distraction, errors, procrastination, and inefficiency for clinicians, often leading to an increased risk of burnout.u003c/pu003enu003c!-- /wp:paragraph --u003ennu003c!-- wp:paragraph --u003enu003cpu003eIn the new study investigating the impact of mobile devices overuse on the general population, Dr. Gupta has found that each hour per day increase in screen time was correlated with a 0.05 to 0.07 increase in body mass index (BMI), most likely caused by online food marketing, distracted eating, and procrastination of physical activities. Moreover, sleep disturbances, daytime tiredness, depression, the odds of using illegal substances, and various cognitive and behavioral issues were also linked to the overuse of mobile devices.u003c/pu003enu003c!-- /wp:paragraph --u003ennu003c!-- wp:paragraph --u003enu003cpu003e“As a pediatric endocrinologist, the trend in smartphone-associated health disorders (obesity, sleep, and behavior issues) worries me.

--u003enu003cpu003eIn order to reduce screen time, Dr. Gupta recommended turning off excessive notifications, deleting social media apps, using traditional alarm clocks, promoting “green time” instead
