Wondering If This Partial Sacrum Is From A Glyptodont Or Large Ground Sloth

[pozbronx2]

Hi, I found this unusal partial sacrum that I can't identify. Its not from a harlan or jefferson ground sloth. I think I have it narrowed down to a glyptodont or eremotherium. The openings are not the primary foramen and correspond to much smaller openings on a jefferson sacrum I've compared it with. I have not found other eremotherium fossils in the area I collect in but this may be an exception. Any info you can provide would be much appreciated. Thanks

Way too small for Eremothere. Let me see if I can dig out my copy of Gillette and Ray.

Welcome to the forum. Nice find and good photos. What do you know about the formation it was found in?

Bob, It was found on a gravel bar on the Coloradao River. Likely from the La Brea timeframe.

Rich, I wasn't having much luck matching it up with photos from Gillette and Ray. Perhaps the text will provide additional info which I haven't read up on yet. Thanks again
