Name:  Ornithomys pictus

Diet:  Carnivore; preys on small to medium-sized vertebrates.

Size:  1.8 m (6 ft) in length, 1.2 m (4 ft) tall at the hip. 

Habitat:  Plains, Open forest, and Floodplains.

Time:  Santonian epoch of the Late Cretaceous

Location:  Eastern North America

Family:  Ornithomyidae

Ornithomys pictus is a member of a superfamily known as the Dipodocyonoidea, a group of highly derived, bipedal cynodonts that developed some time in the late Jurassic.  All members of the group are carnivores, ranging from small, chicken-sized hunters of small vertebrates, to some of the largest terrestrial predators of the Mesozoic.  The largest members are part of the Tyrannotheridae.  Their bipedal stance is thought to coincide with an emphasis on speed, and granted, many Dipodocyonoids are speedy pursuit predators, though some are built more robust and attack their prey by ambushing them. 

This particular genus is known for their cooperative pack-hunting, roving the forests and plains like bipedal wolfs.  These packs have no set hierarchy, though they tend to be made up of only same sex animals.  All members of the superfamily lay soft, leathery eggs.  Female Ornithomys pictus lay between 3-4 eggs in a burrow filled with leaves and sticks.  When the pups hatch, they will remain in the burrow for a few weeks until they are old enough to join the rest of the pack.  Not being true mammals, the young are fed regurgitated meat at first, until the mother starts bringing back fresh meat for them to get accustomed to.  When the mother leaves to hunt, other females will watch over the pups.  Female pups usually stay, while males will eventually head off on their own to find male oriented packs.  Packs contain between 4 and 6 individuals. 

Their prey consists of various synapsids and reptiles, ranging from the size of rats, to animals more than twice their size, which usually takes a team effort to bring down.  They bite at the legs and necks of their prey. 

Other species exist in the Ornithomyidae, all ranging in different colors, patterns, habitats, and prey preferences.  

For the Theriozoic Project! 

I will diverge into the Dipodocyonoidea more in the future, including skeletal diagrams and focus on certain features of their bodies.

Interesting to see a theropod-shaped cynodont. They even seem to fill a simmilar niche as theropods.

It's a mammal, right?

Actually this animal is a highly derived cynodont descendent; but not a true mammal.

So, it's an advanced protomammal/synapsid?

That it is!

Cool. It kinda looks like a convergent evolution to a theropod as well.

What kind of creatures live in this project because maybe I want to draw something for it.

Nice!  If you wish to create a creature, check out the Theriozoic project group page.  A few of the blog entries I typed up talk about a few of the different kinds of animals that can be found in the series.  It's a little bare bones at the moment, but I plan to talk more about the different kinds of creatures in the future.

I noticed that proterosuchids are present but I am guessing phytosaurs are not present.

No, there are no phytosaurs.  Most of the "crocodile niches" are taken up by the proterosuchids and various temnospondyls.

Do you think proterosuchids and even some temnspondyls will take the role of what the dinosaurs did or is that the mammal's place
King-Edmarka's avatar
King-EdmarkaHobbyist General Artist
Well, in this case it would be the synapsids.  Remember, animals like Ornithomys are not true mammals, rather they are cynodonts.  But yes, they take the main role that the dinosaurs have held during the Mesozoic.  The other major tetrapods include the Proterosuchids, temnospondyls, and protorosaurs among others.

Just one last question would there be relatives of helicoprion or have they went extinct

Yes, they will still play a fairly crucial role in the project.  Not sure how long they will last, but they could survive for quite a long time.

I think it weird that there aren't more of these kind of projects, I've found the xenopermian project and that's now dead, this is really cool

Thank you!  Yes, quite a shame.  There haven't been a whole lot of these types of projects.

I don't know why but it makes me think of a badass leptiptidium xD
