Rikache Posted July 31, 2022 Share Posted July 31, 2022 Hi there everyone! This one might be a bit of a tough one. I came across this listing for a possible partial ankylosaur osteoderm or pachycephalosaurus skull armor and was wondering if anyone could help positively ID the specimen. The fossil was found on private ranch land in Harding County, South Dakota. The specimen is small and obviously a fragment so I’m not expecting any clear answers; but in the past I have come across whole ankylosaur osteoderms that looked very similar in terms of texture and coloring, so my untrained eye is inclined to lean towards that conclusion. Important information Locality: Harding County, SD (Hell Creek Formation Size: ~0.8” wide Thank you all so much for your help and for always making me feel like a welcome member of the community, you all seriously rock! Cheers! Link to comment Share on other sites More sharing options...
Troodon Posted July 31, 2022 Share Posted July 31, 2022 Just looks like a bone fragment. Nothing clearly points to either. Might be a pachy skull core fragment. Pachy nodes are solid and do not have pores 1 Link to comment Share on other sites More sharing options...
