TRexEliot Posted June 24 Author Share Posted June 24 (edited) I'm doing some poking around now, and I'm strongly leaning beaver, but input would still be greatly appreciated as I'm not very knowledgeable when it comes to mammals. I am curious if it could be a pleistocene giant beaver tooth or if modern ones are just bigger than I realized.

We'd need measurements to be sure, but from your photos it looks about right for modern beaver in my opinion 1 -Jay “The earth doesn't need new continents, but new men.” ― Jules Verne, Twenty Thousand Leagues Under the Sea Link to comment Share on other sites More sharing options...
Ivaldir Posted June 24 Share Posted June 24 Is the light brown thingy sand or stuck to the tooth? If it's stuck, it probably is tooth cement which points to modern beaver and not Trogontherium Link to comment Share on other sites More sharing options...

All that comes up when I googled that phrase is a compound used in dental medicine... Also, Castoroides is the North American giant beaver. Trogontherium lived in Eurasia.

Sebassie Posted June 24 Share Posted June 24 I think it must be a castor canadensis molar, which is the extant North American beaver. 1 1 Link to comment Share on other sites More sharing options...

Cementum is one of three notable hard parts of teeth (enamel, dentine, cementum) in some taxa (not noticeable in beaver fossils, though). e.g. horse, elephant, and bovid teeth have a prominent cementum component.
