Opabinia Blues Posted January 13, 2021 Share Posted January 13, 2021 Hello! This is a very worn, very eroded ornithischian vertebra from the Lance Formation of Wyoming. It was in three pieces that I recently glued back together, I found all the pieces wrapped in foil together in the box I brought back from the trip. It’s from my trip there this summer, though I don’t remember collecting this specific bone. My immediate thought based on size and shape is Thescelosaurus, though I have seen some small Hadrosaur verts that look kind of like this one. I just hope it isn’t too worn/eroded that no guesses at an ID can be made! Thanks! Link to comment Share on other sites More sharing options...
Troodon Posted January 13, 2021 Share Posted January 13, 2021 The ridges on the side, in your middle photo, are typical of what I've seen in Thescelosaurus vertebrae but you cannot rule out Pachycephalosaurus. Not Edmontosaurus 1 Link to comment Share on other sites More sharing options...
jpc Posted January 13, 2021 Share Posted January 13, 2021 I agree with troodon. Thesc has the ridges, and Pachy probably does too. Hadrosaurs do not. 1 Link to comment Share on other sites More sharing options...
