Return of the dyrosaurid tooth

[Othniel C. Marsh]

Below is the tooth of a dyrosaurid, some of which you may recognise from this thread here. I was originally under the impression that dyrosaurid teeth, like many crocodile teeth, were (unfortunately) non-diagnostic, but it appears that @Anomotodon was able to compile a list of dyrosaurid crocodiles known from the phosphates of the Ouled Abdoun Basin, and the morphology of their teeth, so I wondered if it might be possible to identify mine. Given the fact that my tooth has two carinae, and "medial/lingual curvature with a convex labial" (@pachy-pleuro-whatnot-odon's word, not mine) and no striations, I personally believe this tooth to be that of a Chenanisuchus, but I'm no expert on the matter.

 

 

Thanks in advance for any guidance

Is that list visible in this forum?

 

I have seen two kind of dyrosaurid teeth around and would be curious to know more accurate id.

Ah yes, I forgot to link it. Here it is.

Sounds about right... 🙃

Looks like I was right for a change then. Thanks for the verification, @pachy-pleuro-whatnot-odon.
