Hello,

 

Found this tiny tooth of about 1 x 1  cm in marine Jurassic sediment in the Boulonnais. North of France.

Could this be a marine crocodile tooth, such as machimosaurus?

 

Regards,

 

Niels

OK you bone and teeth people, are you asleep at the switch or what? How did this get no opinions?

Looks like a croc tooth to me, but I'm not a bone of tooth person, so take that lightly.

I am not familar with the location but it looks indeed like a croc tooth ...

Maybe Steneosaurus ... 

More prep will help to Id this tooth. 

Nice find !

Thank you very much for your replies! So you think that this is the tip of a larger tooth that was broken? That makes sense. Maybe I will do some further prep work.

It's the tip of a Machimosaurus sp., identifiable by its blunt shape and anastomosing ridges. Compare against below image (figure 1 from Young et al., 2014. Tooth serration morphologies in the genus Machimosaurus (Crocodylomorpha, Thalattosuchia) from the Late Jurassic of Europe):
