Tormado0 Posted April 7, 2018 Share Posted April 7, 2018 Hello, I found this tooth in my kid’s sandbox in central Kansas. A nearby natural history museum suggested it might be a xenacanth tooth from Pennsylvania period. Just wanted to see if anybody else has any ideas about it. Thanks!

ynot Posted April 7, 2018 Share Posted April 7, 2018 Welcome to TFF! This is a worn shark tooth. 2 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

indominus rex Posted April 7, 2018 Share Posted April 7, 2018 Greetings from Strasbourg and welcome to TFF. Xenacanth teeth are quite rare to find so I believe it is a shark tooth as well. Regards, indominus rex Life started in the ocean. And so did my interest in fossils. Link to comment Share on other sites More sharing options...
gigantoraptor Posted April 7, 2018 Share Posted April 7, 2018 I agree, Xenacanthus lived from the Devonian til the Permian, this tooth looks like a very worn Isurus oxyrinchus from the Mio-Pliocene. Link to comment Share on other sites More sharing options...

Ramo Posted April 7, 2018 Share Posted April 7, 2018 TOrmado0, You could start a new "thread" asking for an ID, but I can tell you with a fair amount of certainty your tooth is Cretaceous in age. Probably a cretoxyrhina (Ginsu Shark). They are fairly common as far east in Kansas as Lincoln county. Even further east along the northern portion of the state. Your tooth probably was eroded out of somewhere west of where you found it, as is the sand in your area. There could be more in there.
