Jon27Thomas Posted August 26 Share Posted August 26 Need help identifying these two vertebrae. The first I think is a mammoth or mastodon. I’m not sure about the second but it’s much to large to be bison or horse. 1 Link to post Share on other sites
Shellseeker Posted August 27 Share Posted August 27 I do not believe that it is large enough for Mastodon/Mammoth.. For Comparison, here is one for Mastodon which is a smaller mammal than Mammoth. xxxxxxx Link to post Share on other sites

I don't have access to my vertebrae for comparison right now, but it doesn't appear to be too large for bison to me. In fact, cow or bison would be my first impression. I know there are other members who have provided size measurements in the past. It may be helpful to you to search the forum for gallery examples. Link to post Share on other sites
fossilus Posted August 27 Share Posted August 27 Both look very much like sloth to me, especially the second. Side views might help determine if they are thoracic or lumbar, based on if there are or are not rib attachment scars. 2 1 Link to post Share on other sites

Jon27Thomas Posted August 27 Author Share Posted August 27 I grew up with cattle and horses and I’ve found dozens of bison antiquus skulls plus thousands of other fossils/bones so I’m pretty familiar with those animals. I’m almost positive it’s something significantly larger. Sloth is definitely possible because I know they have been found in this area before. I’ll upload more pictures when I get time and thanks to everyone for the help! Link to post Share on other sites
Jon27Thomas Posted August 29 Author Share Posted August 29 I took more pictures. Sloth? Mammoth? What do you guys think? Link to post Share on other sites
