New Members Amber Thompson Posted January 28 New Members Share Posted January 28 Hey! Any ideas what kind of tooth this may be? I found it in a fresh water spring. It’s been broken on one side. Link to comment Share on other sites More sharing options...

Balance Posted January 29 Share Posted January 29 Hard to narrow down too much but I believe It’s a bovid broken p2 or p3. Most likely a “modern” fossil of Bos (cattle). Bison dentition is the same as cattle so the photo below should help. It could be bison but it depends on where you are, missing parts you don’t have, etc. 🙂 Jp 1 Link to comment Share on other sites More sharing options...
Harry Pristis Posted January 29 Share Posted January 29 A p4, I think. For comparison: 1 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
Balance Posted January 29 Share Posted January 29 Harry, is the similar “lost” first premolar because these species all go back to a similar ancestor? I again labeled mine incorrectly. Hard habit to break. Wish I’d have taught myself the correct way first. I gotta fix myself regularly. Thank you, Sir Jp Link to comment Share on other sites More sharing options...
Harry Pristis Posted January 29 Share Posted January 29 It is nothing that easy, Jonathan. Mammal bodies, including dentition, are plastic over time, an important feature of evolution. Whales are spectacular examples, moving from land mammal to marine. Dentition changes are common. Look at cat jaws or bears. Humans are losing their third molars, I understand. It seems to be an epigenetic response to external stimuli like diet or environment. For example, horses evolved from brachydont teeth to hypsodont teeth -- from browser to grazer -- as their habitat changed (and the small first premolars became superfluous). Anyway . . . that's my thumbnail understanding of the phenomenon. 3 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
