Views of the chewing surface of the tooth would be helpful.

This appears to be a fragment of a capybara tooth:

This appears to be a piece of either obsidian, or of a very dark black flint.

Bison (or Bos) tooth

[savannahthompsons]

RichW9090, any idea of how old these might be? Is the first item just a rock of some sort?

[RichW9090]

I don't see anything fossil-like in the first photo.

The capybara could be Pliocene or Pleistocene. The Bison/Bos could be late Pleistocene or modern.
