Questions about Pterosaur teeth

[Flaffy]

How does one reliably differentiate Moroccan Pterosaur teeth from similarly elongated fish teeth?
 

Are there any grooves, striations etc I should be looking out for under a loupe?

I'm asking myself the same question as I look at the Pterosaur tooth in my collection. I found this article a bit draining - https://depositsmag.com/2020/12/22/how-to-identify-a-pterosaur-tooth/
Then I found this other academic article with so many photos of Pterosaur teeth (go to Pterosauria Kaup, 1834 chapter) - https://zookeys.pensoft.net/article/47517/list/1/

 

Actually I'm pretty sure that my find is a real Pterosaur tooth, but I'd like to read the expert opinion!

Very little is published on pterosaur teeth from the Kem Kem Group but isolated teeth can be hard to differentiate with other groups (fish/crocodyliforms).   

The KKG has a growing list of toothed species and we are not yet at a point to differentiate teeth between the different species.

 

Ibrahim et al. 2020

 

One way to help identify them is to compare them to known published teeth, not what you see sold.  This is Ibrahim et al. figure on isolated teeth.  They are described by morph types and can be recurved and straited. 

 

 

The paper referred to in the figure:

Yes, this is a very interesting paper. In my previous post there's a link (second one) where you can see the same image and also read about Kem Kem pterosaurus...
