Croc tooth?


Top Trilo

Recommended Posts

I was given this “spinosaurus tooth” a long time ago but when I looked at it again I thought it looked more like a croc tooth. It’s from Morocco and is about 4 cm. Is there anyway to assign a genus to it? I heard it’s hard to identify Moroccan teeth that far

The striations and thick root feels a lot more like Spinosaurus to me. Do you have a cross section picture?

 

Right now the exact ID for the Spino of Kem Kem Beds is still being debated

 

A 2018 paper claims Sigilmassasaurus is indistinguishable from Spinosaurus in the Kem Kem Beds, so all specimens there should be named Spinosaurini indet.

However, a 2020 paper claims Sigilmassasaurus is a synonym of Spinosaurus, so specimens from the Kem Kem Beds are indeed Spinosaurus

Looking forward to meeting my fellow Singaporean collectors! Do PM me if you are a Singaporean, or an overseas fossil-collector coming here for a holiday!

I echo what Andy said. The striations point to your tooth being spinosaurid. I would label this tooth spinosaurid indet.
