One of the best-known ovoraptorids, Citipati osmolskae was vital in broadening our understanding of oviraptorosaurs. These dinosaurs were seemingly caring parents, and at least two have been found buried alive protecting their eggs from sudden sandstorms. The discovery of Citipati, and its associated eggs, was what led paleontologists to realize they had been mistaken about Oviraptor’s eggs.

Like modern birds, Citipati’s tail ended in a pygostyle which would have supported a fan of tail feathers. It used both its wings and these tail feathers to brood its eggs, spreading them out to cover the whole nest. As Citipati was too heavy to fly, it was likely that its feathers evolved for the specific purpose of brooding its eggs. It was a large oviraptorid, about the size of an emu, and had a long neck and relatively short tail. As we don’t have a complete skeleton and crest for Oviraptor, depictions of it in media are usually based on Citipati instead.

Citipati had one of the strongest bite forces of ovoraptorosaurs, and was likely adapted for feeding on extremely tough vegetation. While it didn’t have any teeth, it did have a pointed ridge of bone on its palate that may have functioned for cracking open nuts, seeds, and perhaps even eggs. It may have also been omnivorous, due to the remains of a young troodontid, Byronosaurus, being found in a nest. This may have been food brought for the Citipati’s hatchlings, but it may have also been an instance of brood parasitism!

The Late Cretaceous Ukhaa Tolgod locality of the Djadochta Formation of Mongolia was a harsh arid environment covered in sand dunes and dune fields, with short lived oases sprouting up after rain. Aside from the previously mentioned troodontid Byronosaurus, Citipati would have lived alongside a handful of other dinosaurs. These include fellow oviraptorid Khaan, another troodontid called Almas, the dromaeosaurs Tsaagan, Velociraptor mongoliensis, and Halszkaraptor, the alvarezsaurids Kol and Shuvuuia, the birds Apsaravis and Gobipteryx, the ankylosaurs Minotaurasaurus and Pinacosaurus grangeri, and an indeterminate protoceratopsid. Lizards, small mammals, and turtles were also present here.

Learn to draw dragons by Apsaravis in WYSP

I have always thought that dragons are super difficult to draw, and been dodging them because of that, but I would like to learn to do at least a basic looking lizard. Annnd here is some of my latest attempts. For each piece I had 5 minutes, which is enough time to figure out the key parts, not drawing every scale or detail. There are more dragons in the wysp lesson but I only drew 4 this time. I try to take small steps so I won’t do any harm to learning to draw these. Next time I wish I get more wings and heads.

I really should try to practice these things more often than once in two years.

Dinosaurs of Ghost Ranch

Daemonosaurus chauliodus

('demon reptile, buck-toothed') very fitting name

Saurischia, most likely basal Theropoda

Certainly one of the most basal theropods (if indeed a theropod) yet described anywhere in the world, this tiny terror lived beside the likes of Coelophysis bauri, the much more famous and much more prevalent animal of the Chinle Formation of New Mexico.

The only known skull of Daemonosaurus differs dramatically from all other Triassic theropods. It is short and deep, with extremely large premaxillary and maxillary teeth in the upper jaw, earning the animal its specific name, chauliodus--'buck-toothed'.

Chinle Formation, Ghost Ranch, New Mexico, USA.

Upper Triassic, ~205.6 - 201.6 Ma.

Daily Dino Fact #28

[a-dinosaur-a-day]

Oh man. That's a big question. There are simply too many Avialan Dinosaurs that don't get enough attention.

I know you specifically asked for Cenozoic, but I'm also going to take the time to highlight some great Mesozoic Avialans, because they also never get any attention

Mesozoic Avialans Worthy of Attention:

I know they bounce back and forth a lot because there isn't actually a dividing line between "dinosaur" and "bird", but I have to mention the Anchiornithids - Things like Caihong, Serikornis, and of course Anchiornis itself are really cool fluffy friends that really showcase the variety of feather adaptations

Jeholornis is amazing, we know so much about it and its ecology! It ate seeds, it had a rad tail, it just is aesthetically pleasing

I love Sapeornis because it was essentially the first "bird of prey" if we don't count Microraptor (which admittedly we could)

Confuciusornis is possibly one of the best known Mesozoic dinosaurs of all time. Where the hell is it. Why isn't it in literally anything. Amber Isle even has the tail of Confuciusornis as an option for your character, but gd forbid having an NPC be one I guess

Enantiornithines. There are so many of them. It's kind of insane. Like, these non-Neornithine dinosaurs were essentially *the* birds of the Cretaceous period. I can't even cover all the ones that deserve attention, not fairly anyway. Off the top of my head - Shanweiniao is a great one, as is Bohaiornis, and Gobipteryx, and Avimaia is a wonderful specimen, and Avisaurus is a big hit for Hell Creek fans, and Falcatakely is literally the Tooth-can, and Imparavis was toothless and that's cool, and Lectavis was very like modern shorebirds, and Parvavis is the smallest known Mesozoic dinosaur, and Chiappeavis had a cool tail fan, and I should really stop before this gets too long

On the line to modern birds, Patagopteryx is an early example of a bird that re-evolved flightlessness! I mean yeah things like Utahraptor are too but shush

Yanornis is just such a cool transitional species

Gansus is actually well known for a reason - it was aquatic!

Can you really go wrong with Apsaravis?

Literally the entirety of Hesperonithines

Ichthyornis is just Platinum Tier

And then we have the earliest "modern birds", which are Mesozoic! We've got Vegavis (probably) and Asteriornis! Showcasing how even in the Cretaceous, we had Chickens (ish) and Ducks (ish)

Cenozoic Avians Worthy Of Attention:

Gastornis. Gastornis. Gastornis. Gastornis.

PELAGORNITHIDS. these weirdos responded to the problem of "birds can't reevolve teeth" with "LETS JUST MAKE OUR BEAKS LOOK RIDICULOUS" and they were successful throughout the Cenozoic and just died out bc of the ice age and thats the only reason we don't have any?????? and NOTHING USES THEM??? besides ark which is a travesty

There's a whole score of interesting birds that are in the Passerine-Parrot group but not proper Passerines or Parrots that I've dubbed "Pass-Parrots of Prey" (formerly Parrots of Prey) because they're all raptorial! parrots and passerines come from raptor ancestors!

apparently frigatebirds did the Gull thing before they were frigatebirds and before gulls existed and that's Limnofregata

PENGUINS. They show up RIGHT after the end-cretaceous and have a detailed Paleocene fossil record (a rarity, I assure you) - so we have a great transitional sequence and then on top of it some are HUGE

I deeply love presbyornithids

Sandcoleids are little weirdos I love them

LITHORNITHIDS. They are the base from which Paleognaths evolved and they were flying friends!

Terror Birds. They show up early in the Cenozoic and only died out at the end of the Ice Age. they were a HUGE component of South America's ecosystems and were extremely successful. Also, badass.

Bathornis is basically the North American terror bird (ignore Titanis) so that too

qianshanornis is a cutie with a sickle claw

PLOTOPTERIDS! some booby relatives were like "we want to be penguins" and then they did it! in the northern hemisphere! they were all over the Pacific!

Dromornithids (Mihirungs) are super cool Australian megafowl

I'm a little biased, but I think the screamer-duck I helped described (Anachronornis) is pretty cool

I love Palaelodids (Swimming Flamingos) because they just look Weeeeeeird

I have a soft spot for Zygodactylids because they're basically the usual passerine body but with parrot feet. that's rad

Teratorns were cool vulture-relatives that got REALLY big

There are a handful of terrestrial raptors related to falcons that were notable in the Eocene like Danielsraptor

I deeply appreciate Moa and Elephant Birds for being big friends

Haast's Eagle is one of those things you shouldn't think about too hard

GIANT SWAN OF SICILY

Xenicibis and your club-wings my beloved

Heracles was a Giant fucking Kakapo/Kea/Kaka type parrot and it was RIDICULOUS

I'm ignoring a lot of transitional birds - early members of different groups that tried out unique niches or ecologies that their modern relatives don't do - because if I listed them all this post would get ridiculous. just trust there's tons of interesting small birds that require more text to show how they're interesting than I feel like writing at 5am

STILT OWLS

Sylviornis was another excellent Megafowl

z''l dodos and great auks

Talpanas, aka, the Reverse-Platypus

just for a start

*grabs you by the front of your shirt* Birds throughout the Cenozoic, including today, have significantly more in common with every other dinosaur than any dinosaur has to things like Dimetrodon or Mosasaurus or even Pteranodon. Dinosaurs are a specific family group and birds are extremely nested within it. Including prehistoric creatures in your media but specifically leaving out Cenozoic Dinosaurs is not only a disservice to dinosaurs, but to whatever thing you're creating and also prehistoric life in general. For the love of Gd, just add Gastornis or a Terror Bird or a Pelagornithid to your damn video game/cartoon/comic strip. Dinosaurs don't just *stop* at Archaeopteryx and I am literally losing my mind at this point, please, for me, just do it

(I love @paleopinesofficial and Amber Isle from @ambertailgames, I do, but the fact that there's Dimetrodons and Postosuchus-es and Thylacines and no dinosaurs closer to birds than Archaeopteryx is so infuriating I'm on the verge of tears)

sincerely

Originally thought to be a species of “Ingenia” (now known as Heyuannia), Khaan mckennai was eventually determined to be unique enough for its own genus. While a small, relatively inconspicuous ovoraptorid, its name is derived from the Mongol word for “lord” or “ruler”. In an environment full of larger oviraptorids and dromaeosaurs, I’m not sure Khaan would have felt much like a ruler in its day! Like other oviraptorosaurs, it was probably a herbivore or omnivore, and it had a very strong bite force built for feeding on much tougher vegetation than what other herbivores could eat. In a desert environment, dinosaurs would have needed whatever nutrition they could get, and it was helpful to have special adaptations like this. Perhaps, then, Khaan was the king of crunching on cycads.

The holotype of Khaan is a relatively complete skeleton found together with another similarly sized Khaan. These two, having been buried by a collapsing sand dune and fossilized together, are informally referred to as “Romeo and Juliet.” Further investigation shows that this couple did indeed show signs of sexual dimorphism. While they were relatively similar in size, Romeo had a muscular, more flexible tail, signifying that male Khaans may have shook their tail fans to attract a mate. Meanwhile, the shorter spines on Juliet’s tail vertebrae may have given her more room for laying eggs.

Found in the Ukhaa Tolgod locality of the Djadochta Formation of Late Cretaceous Mongolia, Khaan would have lived alongside some familiar dinosaurs. These include fellow oviraptorid Citipati, the dromaeosaurs Tsaagan, Velociraptor mongoliensis, and Halszkaraptor, the troodontids Byronosaurus and Almas, alvarezsaurids like Kol and Shuvuuia, birds like Apsaravis and Gobipteryx, ankylosaurs like Minotaurasaurus and Pinacosaurus grangeri, an indeterminate protoceratopsid, as well as lizards, turtles, and small mammals.

I’m just going through and posting all my “Good” Paintings here to catch you all up

Name: Velociraptor Takes a Dive

Animals shown: Velociraptor mongoliensis, Asparavis ukhaana, Khaan mckennai

Original Description: After an successful night of hunting, this Velociraptor has stayed up fast her curfew to catch a pair of Apsaravis, who rise early in the morning to feed, and are usually slow to wake. Sadly, due to a combination of Velociraptors weak arms (weak even for dromaeosaurs) and instinct passed down from flighted ancestors to take a leap, a leap that her weak arms couldn't suspend, and so she crashes and burns. Better luck tomorrow night. Also, the Oviraptorids are Khaans, they're quite confused to see a Velociraptor up so early, so they're keeping their distance.

Things I’d change now: Don’t even pretend like you didn't notice the crazyness going on with the shadows.
