Sorry, it's blurry. Hopefully identifiable. It is 3/4" x 1/2". From a late Cretaceous site. Shark or Ray?

Way to blurry to be sure of anything.

Please try to provide better pictures if You want an id.

Yeah, it's blurry but the basic form is similar to some dermal denticles found at Big Brook, NJ (very late Cretaceous site).  As far as I know, no one has identified them as either shark or ray.  In general though, something that large tends to be from a ray.

Brachyrhizodus (sp?)  dent. would be a reasonable guess.
