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.

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!

Strange Symmetries #17: Spiky Surprise

Styracosaurus albertensis was a ceratopsid dinosaur living during the late Cretaceous about 75 million years ago, in what is now Alberta, Canada. Around 5m long (~16'), it was one of the most elaborately ornamented horned dinosaurs, with a long nose horn and multiple elongated spikes on its frill.

There was actually quite a lot of variation in the frills of Styracosaurus, with varying numbers of long spikes and extra hook-like projections present on some individuals. But one recently-discovered specimen nicknamed "Hannah" is especially surprising – it had a noticeable amount of asymmetry in its skull. The left and right sides show different numbers and arrangements of spikes, so much so that if the two halves had been discovered separately they might have been identified as belonging to two completely different species.

Frill arrangements are often used to define different ceratopsids, so if this level of individual variation and asymmetry existed in other species, too, then we may need to reevaluate some of them.
