Unusual Kem Kem Tooth

[DenverEdge]

Here is a tooth I acquired recently acquired. It was mixed in with a bunch of the usual kem kem stuff, gar scales, sawfish barbs, small damaged spino and croc teeth ect. This tooth stood out so I got it and wonder if anyone has any clues?
 

The mesial serrations are smaller than the distal side and they stop about a quarter of the way up the tooth. About 13mm long base is 8 mm from distal to medial and 5 to 6 mm from lingual to labial end.

Maybe something like this

I don’t think it matches that one to be honest it is much smaller and shaped different and curves a lot more to the lingual side and the serrations on that one clearly go all the way to the top.

Possibly some sort of Notosuchia land croc.

Do you have a link or something about Notosuchia from Kem Kem beds? I haven’t heard of them being found there before.

Aside from Araipesuchus, which I'm pretty sure is not your tooth, I don't think I can recall anything described off the top of my head. But I just suggested Notosuchia since they were present all over Gondwana. I can't recall a comprehensive paper on various croc teeth from the Kem Kem if there is any.

 

It could be some other group of Crocodylomorph as well. Or maybe it is theropod, but the first thing that came to mind, and I still think so, is that it's some kind of croc.

@Kikokuryu I do agree with you even if not crocodile I was wondering if it could be some sort of lizard.

Hamadasuchus?

Has anyone seen a land croc tooth from kem kem before? I haven’t seen one look quite like this but being heterodontal I seems like a good lead. It does look like very similar to some teeth a seller has listed as hamadasuchus. Thanks @Runner64 I have a feeling you nailed it.

Here is a small Hamadasuchus tooth I have for your comparison.

@Runner64 now that I look closer all the serrated hamadasuchus Teeth I see including yours the serrations go all the way to the tip unlike mine. Hmmm…

[DenverEdge]

@Troodon do you have any ideas? I’m new to posting here but I have been following your posts for several years.

Sorry out in SD collecting so hit and miss with the forum.  

My first impression is that its not dinosaurian.  Its not typical to have no serrations the distal tip.   Crocodyliforms abound in the KK and may be one of them.  For example Hamadasuchus has a quite varied dentition which are finely serrated.  Unfortunately not much is published on isolated teeth.

No worries man I just figured since I was new I would say hello since I’ve been reading your posts for a while and thanks a lot for your input. It’s in really good condition so I’ll get better pictures in the near future.
