What is this tooth from ?

[Brevicollis]

Hello, i am interested in bidding for this tooth. Description says that its a weirdly formed croc tooth, but i think its a Suchomimus premaxillary tooth instead. From all what i know, croc teeth are always a circle in the cross section and dont have striations. The tooth has no visible serrations, but a flat area at the back. Thats why i think its a premaxillar tooth.

Croc have positional teeth too. I don't see anything here that screams sucho. Happy to be wrong as I've been looking at this one for a few weeks but I think I'd rather it stay an interesting croc tooth .

 

Edit: Can't find much in research material out of this formation so anything is possible I suppose.

Here, some Screenshots i've made. A Sucho tooth, Side and base, and a croc tooth, Side and base :

 

 

see the difference ? I think Sucho matches more.

That assumes every positional tooth is the exact same though and pathological teeth do not occur.

 

Also what is left out here is formation which is required for a positive ID.  Seller has stated its either from Tiouraren or potentially Irhazer formation and not Elhraz where Sucho is found. Based on that I don't think there is any definitive support for sucho over ind. croc. If there is anyone familiar with the locality please correct me if anything is misstated.
