An illustrated assortment of some of the various dinosaurs (all of them shown not to scale for convenience) that inhabit the semiarid Early Cretaceous neighborhood of Utahraptor ostrommaysorum. Among the most unusual of these neighbors are the indeterminate sail-backed Iguanodontian that has still not been formally described, the small but highly-enigmatic Therizinosaur Martharaptor, and the Turiasaurid Mierasaurus, which is a rare Cretaceous and North American representative of an otherwise mainly Jurassic and European family of sauropods.

I noticed u take requests! can I request a deinonychus? I’d love to see one in your style! your line work and anatomy is beautiful ^_^ ps. can I use that as an icon with visible credit?

i am so sorry i misread deinonychus as deinocheirus cuz it's my favorite dino i will see if i can make you what you actually want but have this in the meantime djkfhnjdnghdg i swear i'm not dyslexic

Placodus, Prodryas persephone (as a caterpillar), Avicranium T-posing like a Tamandua and Tyrannomimus wanting to smex the you who is a confused and scared early therizinosaur, as in this doodle i made afterwards

New theropod dinosaur from the Lower Cretaceous of Japan provides critical implications for the early evolution of ornithomimosaurs

Published 7th September 2023

A new early ornithomimosaur provides insights into the early evolution of its group, Tyrannomimus fukuiensis, is based on partial cranial and post cranial material belonging to multiple individuals found in the Kitadani Dinosaur Quarry, Fukui, Japan.

deinocheirus mirificus - ornithomimosaur - late cretaceous

just a big guy whose a real fan of eating Rocks. one specimen (MPC-D100/127) was found with over 1,400 gastroliths in its stomach!! not my choice of meal, but seeing as i dont spend my life eating 60 million year old flora, i can't really judge em.

higher resolution version under the cut!

Ok, another Mexidracon thread because I find this critter just fascinating. In our latest stream I tried to illustrate my point further by showing the proposed sediment probing behavior I assume for this animal.

I did the image on the left on stream but I wasn't that happy with the background so i did the second version above. Again, I don't think these arms were made for fishing, it's arms don't appear flexible or powerful enough to grab or spear fish.

It's relatively short legs also might hint at an overall slower locomotion style, like wading through shallow water, something that would have been abundant in its coastal/deltic environment...

Something that I also let influence this reconstruction is a certain specimen of Ornithomimus which shows traces of feathers on the forearm but NOT of the metacarpals. This might mean that the primaries were just smaller but for the purpose of this reconstruction I went with naked hands... (artwork by Julius Csotonyi)

In this last quick doodle I wanted to show the way I imagine these guys going after invertebrates. This of course assumes many things. Like, that the interpretation of the original authors of this fossil is correct; that the rest of the animal was rather "normal" for an ornithomimosaur or that these limbs had a practical use at all. Another thing that is of course possible is that these arms actually were display structures, very colorful, maybe fully feathered. But I personally prefer the sediment probing idea for now and would avoid yet another display function case.

I hope we find some more specimens in the near future and I would love to see some more takes on this animal. It's been a while since I thought about a new dinosaur this much.
