Tiny shark tooth

Recommended Posts

This past weekend we stopped in for a few hours at Matoaka cabins on the way home from St. Mary's City (a cool non-fossil historical destination).  We found several readily identifiable small teeth and ray plates as well as a few drum teeth and a handful of shells.  My guess with this tooth is a posterior cow shark tooth or Carcharhinus?  Measuring tape is inches on top and metric on bottom.

 

Thanks,

Adam

Doesn't look like a shark tooth to me. You might need to take photos from other angles to figure this one out.

Ok, I'll get out some of the boy's playdough this evening and see what I can do.

No expert, but it doesn't look shark to me either. More like a land based mammal??

I know that land mammal fossils have been found along the Calvert cliffs area so I suppose it is possible.  I had shark tooth stuck in my head to start with but the more I search around the more I doubt it.  On the elasmo site I see that a porgie tooth may be similar.

Thank you.  It doesn't seem to be like the cutting edges of a shark tooth looking at that... granted it could be water worn but I'm not so sure.

Can you take a shot looking straight on at the bottom surface?

Yes, this evening I will put it on some playdough to get some different angles.

Here we go with the "bottom" pictures...I am leaning towards some sort of little mammal tooth after cropping these pictures.

I believe this a a worn and broken fragment of a larger tooth.

I can see that.  So I imagine that is probably about as far as the id will go.

I feel like you have something much more interesting then an other shark tooth. This does look like a mammal tooth to me, it most definitely looks like a molar and/or a herbivore tooth.
