Cretalamna sp., I think. I am known to be wrong, I would wait on someone with more advanced knowledge of shark teeth to chime in.

It might be Protolamna borodini.

Looks like a very tiny weathered Archaeolamna kopingenis.

As this ia. micro tooth, I went smaller.  See attached photo of Plicatoscyllium sp.

Here’s a comparison with a Protolamna borodini from this website- http://www.fossilsofnj.com/shark/borodini.htm

Note the enamel folds on the lingual side of both teeth.
