Brandy Cole Posted February 28, 2021 Share Posted February 28, 2021 The waterways are down enough to hunt some again in my area. This is a find from yesterday, sandy gravel matrix in the river. Pleistocene era. I'm thinking it looks like a spinous process from a large vertebrae, but I'm not positive. I'm also unclear on size differences and other distinctions that could help me narrow down the species. I was thinking possibly bison or camel. Any ideas would be great. 2 Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted February 28, 2021 Share Posted February 28, 2021 I agree, this looks like a spinous process, of quite a large animal at that. Wouldn't be able to help you with the species, but judging from size bison would not seem a bad guess... 1 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...
LordTrilobite Posted February 28, 2021 Share Posted February 28, 2021 Yes, definitely the base of a spinous process/neural spine and part of the neural arch. Both the postzygapophyses are present. Looks like the dorsal vert of a large mammal. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
HuckMucus Posted February 28, 2021 Share Posted February 28, 2021 That does not look like a bison to me. Edited to add: I don't have any in front of me, and it's been a while, but I don't recall the anterior (back side) being concave like it shows in that last photo. That one seems so sinuous. But I'm also used to seeing them with the rest of the vertebrae attached (process, foramen, facets, centrum, etc.). 1 Link to comment Share on other sites More sharing options...
