dbrake40 Posted February 4, 2022 Share Posted February 4, 2022 (edited) Ok I thought I had started to be able to ID bovine teeth and jaws and then this threw my off. This is from a post on Facebook - found in a cave in Kansas. I have posed here with he user's permission. Why is there a three-lobed molar in the middle of this lower jaw? In the past I had though the m3 for cow/bison was the only three lobed molar. But some searching online is telling me otherwise. Also the m3 here looks two-lobed. Can someone clarify?

Harry Pristis Posted February 5, 2022 Share Posted February 5, 2022 It's a deciduous premolar. Here's an example in a deer mandible: 4 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...

Harry Pristis Posted February 5, 2022 Share Posted February 5, 2022 Yes, it will be replaced with a permanent, 2-cusped tooth . . . err . . . the 3-cusper would've been replaced by a 2-cusper if it had survived. 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time?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...
