I found 5 or 6 basic fish tooth shapes in this nano matrix.

I am getting tired so just a teaser...

Will post some more another day.

 

Thanks for looking,

Tony

In the regular micro matrix I did not find any teeth that looked like the barracuda teeth I found in east coast matrix.

I did find these though. Are they?

Tooth 1.

A couple more unknowns.

I think this one is a ray tooth, but it looks different than the species I am familiar with.

And I do not know what to make of this fragment. It does have a concave side.

I tried to find (to no avail) how many known types of teeth there are. It's truly amazing how many you can determine!

Another Galeorhinus sp - Tope shark.

I have only found 2 of these teeth with the pronounced cusps on both sides of the main blade. The other came out of the regular micro matrix.

3 pictures of same tooth

Great specimens and great pictures.  The teeth shown above are from the symphysis area of the jaw.

Thanks Marco!

I was thinking that also.

Do You have any idea about the unknowns?

 

Especially this one...

I think this tooth is from a skate, probably Raja. Your jelly bean looks like a typical phosphate pellet and the tooth posted right after your jelly bean is a breeding male Rhinobatos tooth.

I agree with Eric.  The above tooth looks like Raja and the one unknown ray tooth looks like a male Rhinobatos.  Raja are not common from STH.  See the pictures below of two Raja specimens from the whale pit which used to be a part of the Ernst ranch. Raja teeth can have a wide variety of both root and crown features and can have especially crown feature differences between male and female teeth.
