Untitled Posted September 7, 2019 Share Posted September 7, 2019 Hello everyone, I was wondering what the Maximum size for a late Cretaceous Cretalamna was? I have this tooth from Mississippi which clocks in at 1 29/32” (with root chipping), and can’t find much information as to the largest size that the genus reached in the Cretaceous.

MikaelS Posted December 5, 2019 Share Posted December 5, 2019 Are you absolutely sure it is Cretaceous? It's much bigger than any Cretalamna I have ever seen from the Cretaceous and I have seen many. The width of the neck is more in line with that of Paleocene Otodus. It does however overlap in neck width with Cretalamna but not by much.

Everything else I acquired from him is from Monroe County, which I thought this tooth was too. Edited May 12, 2020 by Untitled Link to comment Share on other sites More sharing options...

I believe your tooth is a Cretodus crassidens. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...

I contacted the person who found the tooth, he told me it’s Pontotoc county, which is Late Cretaceous to Paleocene; too recent for Cretodus crassidens.

Hi Untitled, That tooth is an Otodus lower. It's a little weathered but that helps because it exposes those larger foramina which is a character of Otodus. It may have washed out of the Midway Formation. Jess Link to comment Share on other sites More sharing options...

I was unaware of Otodus in Mississippi, but makes sense now that I think about it more. Ben Link to comment Share on other sites More sharing options...
