Troodontidae teeth in Kem Kem? (or a misidentified Abelisaur perhaps)

Recommended Posts

-Andy-

Recent, I came across several teeth from Kem Kem which intrigued me. At first thought, they reminded me of Troodon teeth, though their serrations were nowhere as big.

 

One seller labelled it as theropoda indet. Another called it Masiakasaurus. I thought they might even be Abelisaurid teeth.

 

What are your thoughts on these?

I believe the first one is hamadasuchus, can't comment too much on the second one. Both very nice looking teeth by the way.

Edit- Looking at the serrations on the second one it does remind me of the characteristics of troodon however i believe that is no longer a valid taxon.

The serrations are far too defined for hamadasuchus imo. I'd lean towards some type of dinosaur but beyond that I am unsure.

 

Lots of funky teeth in Kem Kem like this one 171216203549262.thumb.jpg.b8978e6610d18c64eb1cbda422dd4690.jpg

Here are a couple pics of the "invalid Taxon Troodon" that I have in my collection- 2 of my favorite teeth.

@-Andy-The teeth posted by zekky are clearly odd theropod teeth very very different than those that you are showing.

Noasaurid might be a possibility.

Its possible they are anterior dentary or premaxillary ones.

SNAP!

It's from the Notosuchian crocodylomorph Araripesuchus wegeneri.

 

look at the root- it changes shape after the crown to a very circular and conical shape. This is typical of crocodiles, and a tell tale sign! :) 

Their dentition is highly variable, but they must be the prettiest little teeth!

I agree with you but have a question.  The picture I posted above is from Araripesuchus wegeneri (from Sereno crock paper) which says its from Niger and A. rattoides is from the Kem Kem. I could not find any pictures of those teeth and the paper just had toothless jaws. Clarify species ?  Do they have different teeth?
