Cretaceous Cretalamna Tooth Maximum Size?


Recommended Posts

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.

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.

I contacted the person I acquired it from, and this tooth is from Pontotoc County, so it could be late Cretaceous or Paleocene.  Everything else I acquired from him is from Monroe County, which I thought this tooth was too.

This tooth is from Monroe County, Mississippi, found alongside Cretoxyrhina mantelli; Eutaw Formation.

I believe your tooth is a Cretodus crassidens.

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.

Hello Jess,

 

Thank you very much!  I was unaware of Otodus in Mississippi, but makes sense now that I think about it more.
