Dinosaur teeth from Niger, all dinosaur? ID?

[Raulsaurus]

Hello! A friend get these teeth from Niger, but I do not know the ID and if all are from dinosaur.

I think the first ones are from suchomimus, the smaller ones from rugops and the last one (hervibore) from ouranosaurus.

What do you think? Good ones?

Thank you so much.

Hi Raulsaurus! As for the purported Suchomimus teeth, I believe that all of them are likely to be crocodile. Perhaps there is a chance that the first one could be Suchomimus but I would need a better close up of the enamel texture and both carinae to see whether there are serrations on them.

Ohh really all croc? And the other photos?

Not the “suchomimus “ ones.

Thank you so much.

Not sure how anyone can identify these teeth without a proper provenance: age, formation, locality.

What does the base of the first tooth look like? There are definitely some crocodilian teeth in the pictures. The first tooth, however, may be Suchomimus, but we will need additional pictures.
