Unknown dino tooth? - ID'd as Araripesuchus

[rocket]

Got an unusual tooth some weeks ago, very small (approx 1 cm / 0.4"). First I thought it is a claw due to the shape, but it is a tooth. Reminds to a small sauropod-tooth. Any ideas?

thanks

Photo from the top down perhaps might help with showing the shape.

I try one later, not easy, tiny one...

Reminds to an Ankylsaur-type

It does seem to have a leaf shape from some angles which I think could support your idea of sauropod.

Interesting one, definitely not a typical Kem Kem tooth. Photos from straight angles would really help. It does remind me of certain sauropod teeth, but nothing I have ever seen before from the  Kem Kem beds. Premax/anterior theropod tooth is perhaps another possibility. Or crocidilian? I clearly need more pictures :p

Very interesting tooth! Certainly not a sauropod, sauropods with denticulated teeth were no longer around by mid-Cretaceous. I think it is a (dentary?) caniniform tooth of Araripesuchus rattoides, or possibly another small croc. Constriction at the base of the crown doesn't fit with a theropod and is typical of croc teeth.

 

Might also be one of the incisiform teeth of a juvenile Hamadasuchus, it’s hard to tell them apart.

Ou, a juvenile croc? Interesting, thanks a lot, @Anomotodon. Never thought this could be, but this is a new way for researching in the net to compare

 

e.g. got it! Paul C. Sereno & Hans C.E. Larsson (2009): Cretaceous Crocodyliforms from the Sahara; ZooKeys 28: 1 - 143, Fig 20, pg. 50

 

I add the pdf

Thanks for the additional pictures! I just started getting into croc teeth, but I agree that it does not look like a theropod tooth and is likely a croc tooth. Check out the animals Anomotodon mentioned, they are awesome terrestrial crocodyliforms with very interesting teeth.

thanks. I found a similar in a paper from Sereno & Larsson, looks like Araripesuchus. I would never have thought that this could be a crocodile...
