-Andy- Posted December 17, 2017 Share Posted December 17, 2017 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? 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! Link to comment Share on other sites More sharing options...
Haravex Posted December 17, 2017 Share Posted December 17, 2017 I believe the first one is hamadasuchus, can't comment too much on the second one. Both very nice looking teeth by the way. Matt 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.

zekky Posted December 17, 2017 Share Posted December 17, 2017 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 Link to comment Share on other sites More sharing options...
Troodon Posted December 17, 2017 Share Posted December 17, 2017 Door number 3, none of the above I saw these teeth for sale and asked myself the same question. Was very intrigued with them and almost bid on them but I actually thought price was too high and not worth checking it out. I finally came to the conclusion that I did not think they were dinosaurian but possibly, possibly a Pre-maxillary crocodyliform, could be wrong. There are some weird dudes out there see pictures below. A couple of points why I feel the way I do. The base of these teeth does not look dinosaurian, hollow and thin walled is not a typical characteristic you see on theropod teeth. The cavity appears to go too far into the crown. The shape of the denticles also do not look like theropod although I would like a better view. Too many red flags and too many weird crocs. My two cents...

Troodon Posted December 17, 2017 Share Posted December 17, 2017 @-Andy-The teeth posted by zekky are clearly odd theropod teeth very very different than those that you are showing. Link to comment Share on other sites More sharing options...

iow673 Posted December 28, 2017 Share Posted December 28, 2017 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! Link to comment Share on other sites More sharing options...

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? Link to comment Share on other sites More sharing options...
