Dinosaur fossil cast--Mastodon Tooth

Description

I have a very unique fossil "cast" item from the original fossil.  This appears to be (not 100% certain) a Mastodon teeth.  MY mentors tell me
the roots would be compatible with a Mastodon, and the occlusive surface is clearly not mammoth but more so Mastodonish....seems like a small animal (? juvenile) but with worn down surface.
First class is .50
