Robert Mahorney Posted March 13, 2021 Share Posted March 13, 2021 I believe this is a ball joint of some creature? Found in oklahoma. Seems to be fossilized as it is very hard and stone like. It is lighter than it looks porous as I would expect bone to be. Is this reallllly old or just old? IDK Link to comment Share on other sites More sharing options...
DPS Ammonite Posted March 13, 2021 Share Posted March 13, 2021 A sponge is a possibility. Up close photos will help as will info about the locality, age and rock unit found in. My goal is to leave no stone or fossil unturned. See my Arizona Paleontology Guide link The best single resource for Arizona paleontology anywhere.

jdp Posted March 13, 2021 Share Posted March 13, 2021 Femoral head from a modern animal. The structure of the pit in the middle of the femoral head, which is called the fovea, looks more bovine than equine. Immature cow would be my guess. Could be deer but seems a bit large for that. 1 1 3 Link to comment Share on other sites More sharing options...

I agree with Jason. @jdp 1 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
