bespokemodern Posted December 19, 2020 Share Posted December 19, 2020 (edited) Bone fragment found on the York River in Virginia. It is the Yorktown Formation, Pliocene epoch. I'm wondering if it is a vertebrae fragment, and what species it might belong to. It's convex on one side, and concave on the other.

Rockwood Posted December 19, 2020 Share Posted December 19, 2020 Just maybe it's a cetacean axis vertebra (singular). Link to comment Share on other sites More sharing options...

cck Posted December 19, 2020 Share Posted December 19, 2020 Something bugging me about it being an axis, but that may just be ignorance... Link to comment Share on other sites More sharing options...
Rockwood Posted December 19, 2020 Share Posted December 19, 2020 It's the third photo that seems to indicate it best. Maybe. Link to comment Share on other sites More sharing options...

Rockwood Posted December 20, 2020 Share Posted December 20, 2020 The fossil guy has a good set of photos to illustrate how I see it fitting. fossil guy Link to comment Share on other sites More sharing options...
Boesse Posted January 17, 2021 Share Posted January 17, 2021 Certainly a dolphin axis - however in this state, not possible to identify beyond Odontoceti indet. 1 Link to comment Share on other sites More sharing options...
