Auxiliary carina on mosasaur tooth ?


Brevicollis

Recommended Posts

Hello, as I was just scrolling throug various online fossil sites just for fun, I stumbled upon this small mosasaur tooth from Morocco, wich appears to have an interesting structure on the labial side, wich might be, if I am not wrong here, an auxiliary carina ? Or just an enamel fold with a weird texture ? It doesnt appear to reach all the way to the base or top, and also doesnt seem to create a V shaped trench, so my guess is : pathology, instead of Stelladens mysteriosus ? But these parts could also be lost to some damage, I'm not sure either.

 

Thanks for any opinions and suggestions !

Do you mean with that an angle, maybe created by a facet ?

Im not sure can I call it an true facet, but in similar way.

There's no such thing as too many teeth.

It would be weird if the tooth has only one facet.

 

Also, the edge seems to have serrations. But Im only 3/4 sure those are, as It could also pixels by the low photo quality.

It is always bit difficult with limited pictures.

It is always best if you can observe it in person, since pictures might not show hidden details.

I believe it's an artefact of photography. If you look at the curvature of the tooth in the photographs that show your suspected carina, the tooth curves backwards. Which coincides with the side showing the additional carina being the one illustrated in the other photographs. And over in those, I don't see anything to suggest any unusual morphology or ornamentation...
