A Patreon request for rome.and.stuff (Instagram) - Pachyrhinosaurus perotorum… that I went a bit overboard with lol. I’ve been waiting for an excuse to draw my favorite ceratopsian, and to digitally adapt my old Pachy marker drawing design.

So! Pachyrhinosaurus! As seen above, there were three known species of Pachyrhinosaurus, living in different locations and eras in Late Cretaceous North America.

The oldest, P. lakustai, was native to the Wapiti Formation of Alberta and British Columbia, Canada. It’s known for the extra spikes it has at the center of its frill.

The slightly younger P. canadensis was native to the lower Horseshoe Canyon Formation and the St. Mary River Formation of Alberta and northwestern Montana. It was the largest of the three.

The youngest, P. perotorum, was native to the Prince Creek Formation of Alaska. As this ceratopsid seemingly stayed put during the long, dark, cold Alaskan Winters, it likely had adaptations for keeping warm.

The depiction of a “woolly” Pachyrhinosaurus was first popularized by Mark Witton as a speculative work, but the trope has prevailed. While many paleontologists find a heavy feather covering on a centrosaurine to be highly unlikely, and maintain that the animal’s size and homeothermy would have kept it warm enough, we still have no skin impressions to suggest that P. perotorum was fully scaly. So a feather coating is not completely out of the question (though it is unlikely). Still, I love the look of a woolly Pachyrhinosaurus and how it challenges our previous conceptions of non-avian dinosaurs. Stranger things exist in nature. I had to include a “woolly” option, especially since I already use the guy as my avatar on my paleo Instagram account, SaritaPaleo.

Pachyrhinosaurus was particularly unique in that it seemingly traded off something that had previously worked for other ceratopsians, horns, for a large nasal boss instead. For Pachyrhinosaurus, a battering ram worked better than a sword.

It was herbivorous, using its strong cheek teeth to chew tough, fibrous plants. Perhaps during the dark and cold Winters, P. perotorum would have also dug for roots or even scavenged carcasses. At any rate, from observations of their unusually conspicuous growth banding, it appears growth for P. perotorum would have been stunted during the harsh Winter, but was extremely rapid in the warmer months, an adaptation for the Alaskan climate.

The tundra of the Prince Creek Formation housed a surprising amount of diversity. Pachyrhinosaurus perotorum would have lived alongside smaller ceratopsians like Leptoceratopsids, as well as other ornithischians like the pachycephalosaurine Alaskacephale and the hadrosaurid Edmontosaurus. Theropods such as Dromaeosaurus and Saurornitholestes, as well as a yet unidentified giant Troodontid, lived here as well. P. perotorum’s main predator would have been the tyrannosaur Nanuqsaurus. Small mammals were also somewhat common here, such as Cimolodon, Gypsonictops, Sikuomys, Unnuakomys, and an indeterminate marsupial.

(Btw, the request tier for Patreon starts at only $5 a month. 😉 Link is pinned at the top of my blog.)

i still find it surreal that tyrannosaurs are the most iconic and recognisable large theropod dinosaurs but they were only apex predators on like two continents, even laurasian europe's largest theropods were different

and then ceratopsids are even more nuts, only being diverse large herbivores on a third of a continent and only having any other recognisable presence in one more

I had some spare time so I designed my dino. I'm still not 100% satisfied with the colors, but It's starting to look promising. I really love Ceratopsids they are my favorite group of dinos. Enjoy!

did you know psittacosauruses are one of the dinos we know the most about? heres one of those cuties as a cowboy for halloween 🤠

[jackthevulture]

This was gonna be a fullbody but A) I didnt feel like it and B) I liked the textures on the face so i wanted to focus on it

Nasutoceratops. I love these guys, theyre so cute. Peak cow-coded ceratopsid. big round nose, cow sized, cute horns, from texas? What an aesthetic.

Yet another Ark redesign, this time of the Pachyrhinosaurus.

The Ark Pachyrhino isn't exactly terrible but it could be a lot better, especially the head.

What I did is move the boss on the snout instead of the forhead since Pachyrhinosaurus means "Thick nose lizard" not "Thick forehead lizard".

I also just added a bunch of osteoderms to the body and those tail feather things Psittacosaurus had and that you see on some ceratopsid depictions cuz why not.
