Grimlock Posted April 9, 2018 Share Posted April 9, 2018 Hello Everyone. I would like to get some opinions on this tooth that I found at the Peace a few years back. Thanks Link to comment Share on other sites More sharing options...
Peat Burns Posted April 9, 2018 Share Posted April 9, 2018 Worn Hemipristis serra ? Link to comment Share on other sites More sharing options...
Darktooth Posted April 9, 2018 Share Posted April 9, 2018 Well it has one cusp showing, so not a hemi. Was thinking maybe a worn posterior chub, or something in the lineage. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...

Was thinking maybe a worn posterior chub, or something in the lineage. I see that now. And also I missed seeing the bourlette (pic a little dark ), which upon further inspection I think I see.

Macrophyseter Posted April 10, 2018 Share Posted April 10, 2018 I second Darktooth with a small chub. The presence of a bourlette and at least a vestigial cusp, gives that away. Plus, I think that the serrations might be a little too small for a hemi. If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM!

Harry Pristis Posted April 10, 2018 Share Posted April 10, 2018 I assume that "chub" refers to Carcharocles chubutensis. "Chub" just confuses newbies. Beyond that, I don't think any C. chubutensis have been found in Florida. Carcharocles is probably best thought of as a chronospecies, and the Peace River sediments are too young to contain anything other than C. megalodon. This is a very small tooth, but probably in the range for a newborn (young megalodons often have atavistic lateral cusps). 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...
