Serrated Unknown (Croc?) Tooth

[Omnomosaurus]

Hola folks,

 

Just picked up an itsy-bitsy, teeny-weeny tooth from the gift that keeps on giving; Morocco.

 

It was sold as a juvenile Spino tooth, but I'm thinking there's a better chance of it being croc?

 

I liked the look of it, so bought it anyway.

 

Location given: "Hamada gu Guir, Kem Kem Basin, Morocco."

 

Not sure if you can pick out from my crummy photos, but there are definitely denticles present on the carinae, running all the way from tip to base of the crown.

 

There is also fluting present on both the labial & lingual sides of the tooth, running the full crown length.

 

 

The cross-section appears to be roughly oval, though could be considered circular (it's hard to tell with the shape of the base).

 

 

Denticles most noticeable in this one:

 

 

Profile of denticles can also be (kind of) clearly seen on the right side of the tooth here:

 

 

And a couple more shots:

 

 

With the lingual curve and denticles, I'd assume croc from this part of the world, though I've read that labial/lingual curves can be found on Baryonychidae....if only haha!

 

Any input on narrowing down exactly what it might be would be much appreciated.

It's croc. Spinosaurid teeth are not that curved. There are a number of crocodiles present in this fauna so I don't know exactly what species it is.

I agree with gigantoraptor's response! I have the same from the Kem Kem. They are quite common.

Nice specimen.

 

I posted this once before, but given it is relevant to serrated croc-type teeth, I will post it again, even though its from a different part of the world.

That's a very useful piece, thanks!

 

Seems I was right on the croc ID. I was drawn to it because of the unusual colour pattern, but it would've sucked for someone else to have bought it, falsely thinking it was a Spinosaurus/Suchomimus tooth (both were mentioned in the sale listing).

 

Based on names I've seen thrown around for the Kem Kem, I'm guessing it's probably Elosuchus or Hamadasuchus? Crocodylomorphs aren't usually my thing.
