North Carolina Mosasaur Tooth

Recommended Posts

MikeR

I have decided to take a break from shells and delve into the vertebrate world for awhile.  In going through several trips worth of North Carolina Cretaceous material, I came across this incomplete tooth which I believe is from a mosasaur.  Reading through prior posts I know how difficult they are to identify but I am hoping that there are enough distinguishing characteristics to be able to identify by genus.  The size of the tooth is 12 mm x 12 mm x 6 mm.  I took pictures with my iphone so if the consensus is better quality pics are needed, I'll drag out the DSLR.

@MikeR

It's either Mosasaur or Deinosuchus. I will send your photos to Todd, though @sixgill pete may also be able to help.

I'm not really sure about this one. I have a very similar piece of a tooth that is probably from the same location. Only it is the tip section. A few people have looked at it and suggested some type of fish. I still believe it is mosasaur.

Thanks Jack.  I would be surprised if it was Deinosuchus.  I have a quite a few and they are all conical whereas this tooth is quite oval and small.

Thanks Don.  I would surprised if this was fish as well but I don't know what I don't know.

Admitting you "don't know" is the 1st step to enlightenment. It's much better than the people who don't know they don't know and think they know everything. :headscratch:

Mosasaur teeth do not have all those ridges running down them.  They are pretty smooth except for a single, slight ridge.  On the other hand, plesiosaur teeth do look a lot like the tooth you are showing.  If I had to guess, I'd call that plesiosaur.

Mosasaur of some sort.   Heavily faceted.

Here’s a faceted one from Greens Mill Run in Greenville NC. I don’t know the genus.

Hi Al Dente,

 

Someone talked about Platycarpus elsewhere on the forum recently.  I believe he noted that a researcher was at least leaning against Platycarpus being present in the Maastrichtian of Morocco, and suggested another genus.

can we have a straight on shot of the basal cavity? Also am thinking that some of the pterygoid teeth may be more ornate than the jaw teeth. (not sure on this though)

Thanks for looking Don.  I hope that this image is not too blurry.

Don't worry.  It's only temporary.

I'm in the mosasaur camp! That elliptical basal cavity is a good clue.
