The giant ground sloth Glossotherium rests as a flock of Yellow-headed Caracara keep him tick free.

The diminutive Thikarisuchus xenodentes (1/2 scale) wanders the forest floor at night. I'm glad the Blackleaf has another taxa and I'm so grateful to have helped in the process. There's more research from yours truly on this guy down the pipeline, so stay tuned! #sciart #crocodile #paleoart #clayart

A small brown crocodile with a flat head wanders on upright legs on a dark forest floor. A flashlight illuminates the head and front arms. Thikarisuchus xenodentes (Elton) is looking with beady yellow eyes for their next meal.

The Thikarisuchus model inside with a neutral black background. The detail is more noticeable, showing an armored tail lacking the ridges of aquatic crocs we know today.

A closes view of Thikarisuchus, showing off it's variable dentition. The front of the mouth has conical spikes, while the back has more compressed lanceolate teeth and then shearing rectangular teeth. The back teeth occlude with a ridge on the dentary.

Happy #FossilFriday! Meet #Thikarisuchus xenodentes (#MOR11969)! The skull of this small #Cretaceous #crocodyliform fits in the palm of your hand. Thikarisuchus was named this week in a Journal of Vertebrate Paleontology paper by #MontanaStateUniversity alumnus Harrison Allen and colleagues.

Our #marchofthemammals2025 wrap up post! Probably the smallest average size so far, which makes Palaeoloxodon look especially impressive!

As always thanks to @shunosaurus.bsky.social for organizing this! I've got one more little follow-up for this years formation theme, so stay tuned!

#marchofthemammals2025 day 26, a mother Dinopithecus ingens and her baby, going for a ride

#sciart #paleoart

Vector illustration of Dinopithecus ingens, a large cercopithecid monkey from the Late Pliocene and Pleistocene of east Africa. The large baboon is a female, with a young child clinging to her back. They are both a dark tan color on thier fur, with the mother having a light ruff on its cheeks

#marchofthemammals Day 30: Dinopithecus ingens
Dinopithecus chows down on a handful of sourplums. Figured it would be fun to give the giant baboon red fangs without falling into the macropredatory trope.

Vector illustration of Beatragus antiquus, a species of Hirola antelope from late Pliocene/early Pleistocene Ethiopia. It is very similar to the living hirola, with longer, straighter horns, and a darker face and back.

A very angry Ancylotherium hennigi for day 23 of #marchofthemammals2025

#sciart #paleoart

Vector Illustration of Ancylotherium hennigi, a large schizotherine chalicothere from late Pliocene Ethiopia. It is rearing up with its claws beared, ready to stomp an attacker. It is similar to a large horse, with a long neck, claws, a stocky body and a dome on its forehead. It is sandy brown in color, with dark on its face, shoulders and feet

#marchofthemammals2025 Day 27: Ancylotherium henningi
Ancylotherium keeps her distance from Dinofelis. They probably wouldn't attack something so large, but better safe than sorry.

On to our last week of #marchofthemammals2025, the savannas of Early Pleistocene Ethiopia! Here's Dinofelis petteri chilling on a tree branch

#sciart #paleoart

Vector illustration of Dinofelis petteri, a bobcat sized sabertoothed cat from the Pliocene of Ethiopia. It is relaxing on a large tree branch, looking out at the horizon. It resembles a small leopard with a notably shorter tail and a broad snout. It is orangeish in color with dark spots that stretch into long rosettes towards its back

Dinofelis scratches up against a dead tree. Welcome to the Shungura Formation! Over the final week of March we'll reconstruct some of the extinct megafauna our ancestors once met.
