Large Kem Kem Theropod Tooth That Doesn't Look Like A Typical Carcharodontosaurus

[AJ Plai]

I just got this strange tooth that's almost 3.5" long that I assumed it came from a Cacharodontosaurus. But upon closer inspection when I got it the shape of the tooth doesn't look flattened nor blade-like but seem to be very bulky unlike typical Carch teeth I have seen. So I was wondering if this is a special positional tooth that doesn't fit the standard shape of normal Carch tooth? It's also slightly bent and twisted as well, not sure if that's natural or some form of pathology.

The previous owner thought it's a Deltadromeus tooth but that doesn't seem likely since Deltadromeus teeth (or those theropod teeth attributed as) shouldn't be this big, but I could be wrong. What's are you guys opinions on this?

This tooth appears to have some restoration and that sometimes makes it difficult to tell what type of tooth it really is. I do have some very orbust-looking Carch teeth in my collection. they are typically premax teeth.

Hi AJ nice big tooth. What most collectors associate with on Carch teeth are the blade like teeth, I call them your stereotypical Carch tooth. Those teeth are typically your maxillary ones which are the most compressed in the jaw but also can be your mid-distal dentary teeth. The oval cross section of your tooth reminds me anterior dentary tooth but I cannot see where the serrations are. So If you look at your last picture (bottom view) can you mark where the serrations pop out?

I agree with you, being that size its most likely a Carch.
