sseth Posted May 25, 2017 Share Posted May 25, 2017 So I have been going through mountains of Pleistocene material from Iowa and classifying the material by species. I have a lot of Bison material, Deer, Elk, Stag Moose, Sloth, Beaver (Small and Giant), and much more. I did come across one sacrum that I can not classify. Not sure if it is small bison, Cervalces (Stag Moose), or large Elk. I am sure someone here might be able to help me out. I am much better at those pesky marine reptiles and dinos than the modern mammals. Thanks in advance.

Boesse Posted May 25, 2017 Share Posted May 25, 2017 No idea - terrestrial mammals are typically beyond my scope of knowledge. That being said it distinctly reminds me of ungulate sacra, not that that helps much. Link to comment Share on other sites More sharing options...
NWGeoFan Posted May 25, 2017 Share Posted May 25, 2017 Dont think its a Bison but still I am unsure, but heres a diagram of a modern Bison Sacrum which should give a helpful comparison! Also if you could get a photo of the top, that would be helpful. "I am going to dig up dinosaurs whether they are liquid or solid" Link to comment Share on other sites More sharing options...

Also if you could get a photo of the top, that would be helpful. I tend to agree not bison. My leaning is Cervalces but could be very large elk, could even be something else. _____________________________________ Seth www.fossilshack.com www.americanfossil.com www.fishdig.com Link to comment Share on other sites More sharing options...
Osteobyte Posted May 25, 2017 Share Posted May 25, 2017 I'm leaning toward elk because of the fused spinous processes/medial sacral crest, u-shaped superior opening of the sacral canal, and shape of the cornu?/distal lateral processes?. But I am unfamiliar with moose. 3 Link to comment Share on other sites More sharing options...
