sharko69 Posted June 11, 2017 Share Posted June 11, 2017 Found this huge tooth today in a Texas creek. Not sure if cow or first bison. The tooth is very large compared to the cow teeth and jaws I have. The enamel is over 50mm in length. Thanks for any help. It is a pretty tooth whatever it is.

Harry Pristis Posted June 11, 2017 Share Posted June 11, 2017 The significant measurements are the length and width of the crown, not the crown height. It's definitely bovid, cow or bison -- an m3. If I had to guess without the important measurement, I'd say cow.

Compare to this: but size doesnt seem to probe anything. i found this yesterday on top of sand at the river thames in central london at low tide. crown length 3.9cm and overall height of tooth 7.7cm. it could be a bison based on many different things people of fossil forum have been posting, but i highly doubt its as old as that. and there are so many cow teeth in this river. people have apparently found bison teeth in this river but i reckon youre 1,000 times more likely to find a cow tooth. anyway its the largest cow tooth ive found yet Link to comment Share on other sites More sharing options...
Harry Pristis Posted July 30, 2020 Share Posted July 30, 2020 You're right about the uncertainty of identifying an isolated tooth. All circumstances -- condition, context, size -- have to be considered. There has been a butchery operation along the London Thames for more than a thousand years, so your estimate of 1,000 cow to one bison is probably conservative. 2 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...
