Palaeogaleus or Galeorhinus

[Hipockets]

This is from the NE Cape Fear river in NC, Pee Dee formation, Late Cretaceous. Scale is mm. ...Thanks

It might be Palaeogaleus which have been documented from the Peedee. Here's a picture of a Palaeogaleus.

Truthfully I've seen a number of researchers over the years switch species back and forth between Palaeogaleus and Galeorhinus.  Palaeogaleus is an extinct triakid genus which had a dentition similar to both the extant Galeorhinus and Triakis genera with tooth features similar to both  All are houndsharks.  So I wouldn't be hung up on the genus of your specimen.

Thanks Eric and Marco. It looks like it could be an eocene pachygaleus lefevrei that found its way down to the Pee Dee. After talking with Plax, he is more familiar with the site than I , he has found eocene material mixed in from time to time.

Am actually thinking that the one pictured in the ICM Paper (thanks aldente) looks more like your specimen than the one pictured as Pachygaleus in

  There is Eocene material at the site for sure as it's a mixed lag but am not sure of the strictly diagnostic features of either of these taxa are. Perhaps Marco says it best.
