Tusk/horn Fragments Or Bone Fragments?

Recommended Posts

My son found these various pieces also near a creek in Southwest Ohio. They don't have "marrow holes" like many of the bones we find so we are wondering if they might be fragments from mastodon tusks or bison horns.

They are probably bone shards, where the concavity is the edge of the 'marrow cavity'.

If you do a TFF forum search for "Tusk", you will see a lot of examples. Pieces of mammoth tusk (Ivory) tend to have patterns of lines called Schreger that are diagnostic. Like these.

Looks like a typical weathered bone fragment. Remember tusks have growth rings like trees. That's the best way to tell bone from tusk. Bone will not have growth rings. See the above example from Shellseeker.
