TRexEliot Posted June 6, 2021 Share Posted June 6, 2021 Just found what appears to be some kind of rodent molar in big brook, New Jersey. I know that there are both pleistocene and modern mammal fossils at this site, is there any way to tell if this is a fossil or a modern animal?

TRexEliot Posted June 6, 2021 Author Share Posted June 6, 2021 Thanks @Rockwood! Any idea on the age? Not sure how quickly teeth blacken like this. Any chance it's pleistocene, or just modern? Link to comment Share on other sites More sharing options...
Rockwood Posted June 6, 2021 Share Posted June 6, 2021 You should wait for a second opinion here to be sure. The brooks have a lot of iron containing minerals in them. That and the tannin from surface water darken bones, and to a similar degree teeth quite rapidly. Rabbits tend to reproduce rapidly too. In such a populated area I expect a few become sail rabbits, flattened so that they sail like a Frisbee. Link to comment Share on other sites More sharing options...
