diginupbones Posted February 10, 2021 Share Posted February 10, 2021 Found in north central Nebraska. Miocene. I’ve had this in my collection for a while, I don’t know why I overlooked getting it identified. Really a nice little specimen. Link to comment Share on other sites More sharing options...
fossilus Posted February 10, 2021 Share Posted February 10, 2021 Looks like a calcaneus. Maybe a larger arteriodactyl or horse, maybe rhino? I can't help much more than that on miocene. 1 1 Link to comment Share on other sites More sharing options...

jpc Posted February 10, 2021 Share Posted February 10, 2021 very large mammal calcaneus. I think it is too long to be a perissodactyl (horse or rhino), so maybe a large artiodactyl or even an entelodont. 1 Link to comment Share on other sites More sharing options...
Mahnmut Posted February 10, 2021 Share Posted February 10, 2021 hello, To me the shape looks more artiodactyl than perissodactyl, no idea about entelodont calcanea though. The size is in the upper cow-range.

diginupbones Posted February 10, 2021 Author Share Posted February 10, 2021 Thanks everyone for getting me pointed in the right direction. I did some searching and found some really good info right here on the forum. It looks like everything is pointing to bison calcaneus. Link to comment Share on other sites More sharing options...
PaleoNoel Posted February 10, 2021 Share Posted February 10, 2021 Agree with the others, calcaneus for sure. Bison or cow seems to be the likely candidate. If it were either of those it would have to be much more recent than Miocene. Link to comment Share on other sites More sharing options...
jpc Posted February 10, 2021 Share Posted February 10, 2021 I disagree. Look at the angle of the sustentaculum (fig A-5) compared to yours.... yours is almost 90 degrees. Also look at the shape of the shaft opposite that same sustentaculum... same A-5. The bison has a large protuberance, whereas yours is flat all along that surface (more like the cow in Fig B-5). The preservation also looks Miocene, not recent or Pleistocene. I don't know what to call it, but I would not call it Bison or Bos. I know there are some here who know their Pleistocene critters way better than I do. Whatta you folks think? Link to comment Share on other sites More sharing options...

I see similarities in both bison and cow but neither one seem to be an exact match. @Harry Pristis Link to comment Share on other sites More sharing options...

I see similarities in both bison and cow but neither one seem to be an exact match. @Harry Pristis I concur. I did some comparisons earlier, and couldn't find a good match. The calcaneum is the right size for bison, but it has the wrong conformation, I think. If it is indeed Miocene in age, there a number of possibilities. A good comparison collection would be almost essential for an ID is this case. http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...

It was a little longer than 3.5 inches, but it was carnivore!!! You might compare the shape to yours. http://www.thefossilforum.com/index.php?/topic/42376-calcaneum-crab-claw/ 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
Lorne Ledger Posted February 11, 2021 Share Posted February 11, 2021 Looks very camelid to me - lots of similarities. It's nothing Pleistocene. Beautiful piece!!!! 1 Link to comment Share on other sites More sharing options...
