This is a some kind of tooth from the Eocene. I found it a few feet from this shark tooth I also found but couldn't figure what this is. I was imagining fish?
Microscope images included and also showing it is transparent in the light where the tooth gets thinner. No serrations.
People didn't like that I used American currency so here is Ancient Rome, , Canadian, Belgian and wheat cents for any time travelers or old timers.
I lost my snarge ruler unfortunately.
