Hey all,

I collected a lot of micro shark and ray teeth over the years in the ENCI and i still have a few that i couldn't identify. Hopefully some can be put to a name. Thx in advance.

Regards,

Arno

These two are Heterodontus:

Thx. So these are juvenile teeth because they don't look like the other anterior teeth of the Heterodontus found here?

The possibility of rhinobatos was explored but since there is only one rhinobatos known in the maastrichtian there was a little doubt. But the possibility of it being a male is quite interesting.

Arno

Yes, they are juvenile teeth. Here is one I found in the Maastrichtian Peedee Formation in North Carolina:

For the first tooth we need better views - preferably the standard views provided in articles on shark teeth: a straight-on view of the front, back, and a profile view. I realize it is difficult to set micro-teeth for photography but it is also difficult to identify unusual teeth from non-standard views.

The second tooth may be an incomplete Ganopristis oral tooth. If Pseudocorax had a symphyseal position, I would guess it would look like the fifth tooth. I agree that the sixth tooth is Rhinobatos. It bears more developed lateral uvulae than normally seen from the locality.

I think that eighth tooth is some kind of dasyatid. More views would help.

The taller pointed tooth with the Heterodontus anteriors looks like it could be Raja or a relative of it.

Hi all,

It has been quite some time since my last reply in this topic but I had time (and better equipment) to hopefully make the correct pictures of some of the teeth.

The first picture is a Rhinobatos mariannae but i am not sure the tooth in the second picture is one too. I feel that there are some differences there but i am not sure to be honest.

I figured this one out. It is a rather small female Squatirhina kannensis though due a little damage on the back i have mistaken it to be something else.
