Well, let's start this off with the thing in my profile pic. This is an older piece I done while I should have been paying attention to a class zoom call (~Feb-March 2021). The dinosaur that I intended to depict here is the enigmatic TMP 2002.76.1, more often referred to as the "Dinosaur Park Pachyrhinosaur" or "Iddesleigh Pachyrhinosaur." This fossil consists of a nearly complete skull and postcranium found at the very top of the Dinosaur Park Formation, and represents the earliest occurrence of a pachyrostran in the fossil record, roughly 500,000 years older than Achelousaurus and 1,000,000 years older than the earliest Pachyrhinosaurus proper. This specimen doesn't preserve the parietal portion of the frill and as such is difficult to resolve phylogenetically. It consistently groups in a polytomy with the previously mentioned genera, so it may belong to either of them or be a new taxon altogether. Interestingly the animal has pathological feet, with several of the phalanges of the hands and one foot showing stress fractures, resorption and destruction of distal elements, likely losing some of its toes.
For my part, I kind of dropped the ball on this one. I restored it as a kind of generic Pachyrhinosaurus. I like my work well enough on its own, but it doesn't really represent the fossil itself all too well. Mainly the area between the boss and beak, which I restored with two lateral scales more like in Pachyrhinosaurus canadensis, and the area between the nasal and supraorbital bosses which I made way too small. Additionally, though the frill is not known in TMP 2002.76.1 it probably wasn't the Pachyrhinosaurus frill I gave it.
I may revisit this in the future and give this fascinating fossil its proper due
