here's today's #Paleostream sketches!!! today we drew Cretoxyrhina, Barinasuchus, Clidastes, Hypuronector

An unfortunate hadrosaur has been washed out into the western interior seaway, and it's attracting quite the crowd.

Ginsu shark

Cretoxyrhina mantellii

A species of large predatory shark from the late Cretaceous, Cretoxyrhina mantellii (meaning 'Mantel's Cretaceous sharp-nose'), commonly known as the Ginsu shark, fed on medium- to large-sized fish and marine reptiles across the world's oceans. Massive and fast, the Ginsu shark was a top predator in its ecosystem, regularly competing with mosasaurs and other predatory fish in such regions as the Western Interior Seaway.

Results from todays flocking

The first sketch was cretoxyrhina, which I could do at the same time as everyone because eating, so I did this while everyone was posting In like uh ten minutes

Then we did

Barinasuchus

Clidastes

Hupuronector

These are great

Amber Beach Dinosaur Zoo Headcanons

I’m just gonna list the Locations at the zoo first.

Pattern is just: Location Name -> species Present

Hell Creek River Ride -> Triceratops serratus, Thescelosaurus centreus, Pachycephalosaurus giganteus

Tyrant Kingdom -> Tyrannosaurus imperiosus, Leptoceratops dentomagnus

Gobi Plaza -> Velociraptor penna, Saichania maximus, Protoceratops luna

Gobi Desert Hall -> Achillobator nychius, Deinocheirus morgani, Tarbosaurus minimus

Hadrosaur Hotel -> Edmontosaurus neoregalis, Parasaurolophus lenis, Iguanacolossus gigantonychus

Titanic Hills -> Isisaurus americanus, Alamosaurus centreus, Magyarosaurus spec.

Western Interior Aquarium -> Mosasaurus neoprismaticus, Elasmosaurus melanins, Cretoxyrhina regalis, Pteranodon ceratus

Plesiosaur Feeding Show -> Plesiosaurus macrocheirus

Argentina Alley -> Carnotaurus terra, Notoceratops roryii

Morrison Safari -> Stegosaurus neoungulatus, Allosaurus tyrannimimus, Diplodocus megalocaudia, Brachiosaurus titanis

Egyptian Swamps -> Carcharodontosaurus carcharoserratus, Spinosaurus serratus

———————————————————————

-Titanic Hills has guests enter heavily armored trucks due to the fact that two of the three present species could stomp an average car to pieces

-Tyrant Kingdom is shockingly the least popular exhibit since its Tyrannosaurus named Ares prefers to sleep rather than roar, and dinosaurs don’t even roar.

-3/5 times someone goes to Gobi Plaza, at least on Velociraptor has broken out.

-Gobi Plaza and Argentina Alley are neighboring areas, and as such the Velociraptors make a point to terrorize the nearby Carnotaurus exhibit.

-Hadrosaur Hotel is in fact a series of hotels that are on a hill overlooking a massive field land exhibit, which is often the site of a weird turf war between the Edmontosaurus and Parasaurolophus herds. The Camptosaurus herd wants no part in it.

-Ares the Tyrannosaurus has a strange love of angering the nearby Pachycephalosaurus at the Hell Creek River Ride, luckily, none of the Pachycephalosaurus have injured anyone… yet.

-The Morrison Safari is the most recent attraction to the park, but possibly the most Dangerous seeing as the Allosaurus CANNOT CONTAIN THEIR EXCITEMENT, because more than once they’ve charged to the Jeep and demanded being pet by the visitors inside.

-The Zoo’s Allosaurus pack of about seven is very docile towards humans, shockingly.

-There’s only one Spinosaurus at the zoo, it hates everything, but the Carcharodontosaurus mating pair in the nearby stadium.

-There’s a total of 20 velociraptors in the Velociraptor exhibit, 15 adults, 5 babies.

-The velociraptors are all named after pastries because there is at least a baker’s dozen of them (AKA 13, for the uninformed), they are named Cake, Cookie, Donut, Cream, Butter, Velvette, Dough, Souffle, Cupcake, Chocolate, Chip, Mochi, Mint, Mixini, and Churro, though the babies are named after cheeses for some reason, they are Cheddar, Provolone, Mozzarella, Shredderina, and Swiss.

my hand is hurting a little from drawing stuff for work, so today's flocking sketches are simple and silly. cretoxyrhina (with a pteranodon), barinasuchus, amplectobelua, clidastes and hypuronector

SHARKS!!

From their first appearance around 370 million years ago, cartilaginous fishes have been emperors of the oceans. This list does include critters that are more shark-adjacent than true Elasmobranch sharks.

Cladoselache (D) - Xenacanthus (D) - Stethacanthus (D)

Acanthodes (C) - Squatinactus (C) - Falcatus (C)

Helicoprion (P) - Ptychodus (K) - Edestus (C)

Megalodon (Ng)

Hybodus (K) - Frilled Shark (H) - Goblin Shark (H)

Archovember 2024 Day 25 - Pteranodon longiceps

As one of the main species to make up the mythical “Pterodactyl” conglomerate, Pteranodon longiceps is possibly the most familiar pterosaur to the public. However, most people don’t know much about the real animal behind the pop culture monster. Living in the Late Cretaceous USA, Pteranodon is also the most well-known pterosaur to science, as over 1,200 specimens have been found! It was the first pterosaur found outside of Europe, the first toothless pterosaur found, and, before the discovery of the giant azhdarchids, was also the largest pterosaur known. Pteranodon is also one of the few prehistoric animals with confirmed sexual dimorphism, and it’s a bit extreme to boot! The larger male Pteranodons had huge pointed crests and an average wingspan of 5.6 m (18 ft), while the smaller female Pteranodons had small, rounded crests, wider pelvic canals, and an average wingspan of 3.8 m (12 ft).

Pteranodon lived around the Western Interior Seaway, a massive sea that split North America in two during the Late Cretaceous into the Early Paleocene. With wings shaped like modern day albatrosses, Pteranodons were likely gliders who relied on thermals, but did seem to be more capable of sustained flapping. As one would expect, their diet was made up mostly of fish, though they may have eaten invertebrates as well. With their more heavy build, they could probably dive into the water like modern day gannets, folding up their wings and plunging beneath the waves, snatching up fish with their pointed, birdlike beaks. Pteranodon crests were most likely for display, as there was variation between not only males and females, but also individual males. As females were twice as common as males, they were probably polygynous, with males competing for the mating rights in rookeries of females. Competition was likely not physical, and instead would depend on females determining the age and fitness of males based on the size of their crest.

Pteranodon has been found in both the Niobrara Formation and the younger Pierre Shale Formation. Some possible fragments from the Mooreville Formation and Merchantville Formation also exist. While Pteranodon was much more common, it would have lived alongside, and possibly competed with, the fork-crested pterosaur Nyctosaurus and the toothed seabird Ichthyornis. It is probable that Pteranodon lived in offshore rookeries, raising their flaplings far from land-based predators, as most fossils are found far from what would have been the Interior Seaway’s coastline. Under the waves, Pteranodon would have hunted a variety of fish, ammonites, and squid. It would have come across sea turtles such as Toxochelys, plesiosaurs such as Styxosaurus, and flightless birds like Parahesperornis. It would have had to look out for mosasaurs like Tylosaurus and sharks like Cretoxyrhina. Aside from birds, most Pteranodons would rarely come across dinosaurs. Their main exposure to dinosaurs would be corpses, like that of the hadrosaur Claosaurus, being swept out to sea.

Cardabiodon ricki

A robust, heavyset shark, Cardabiodon ricki (meaning 'Cardabia tooth of Rick') dominated antitropical seas of the Late Cretaceous. Reaching up to 18 ft (5.5 meters), C. ricki coexisted with predatory marine reptiles like pliosaur Brachauchenius, and other macropredatory sharks, like similarly large-bodied Cretoxyrhina and Cretodus, in the Western Interior Seaway.
