Pilobolus Posted June 26, 2017 Share Posted June 26, 2017 It's been a good week for fossiling in New Mexico...found this one in a dry wash in west-central NM. The nearest upstream units were (from nearest to far) kmf-Menefee, kpl-Point Lookout Sandstone and the Satan tongue of the Mancos shale (kms). I've always thought of the Western Interior Seaway as fairly shallow and the shark a deep variety, but the lit says the extant cousin patrols 100m to 1,300m and the WIS was as deep as 750, so there's habitat, I would think. Thoughts? Thanks! Link to comment Share on other sites More sharing options...
Trevor Posted June 26, 2017 Share Posted June 26, 2017 Looks either Goblin or Sandtiger. If you look on a geological map for your area and observe that the area where you found the tooth was Cretaceous then the tooth is most likely a goblin. : ) Link to comment Share on other sites More sharing options...

Thoughts? Modern goblin sharks are deep water but Scapanorhynchus teeth are found in shallow marine deposits and possibly brackish water too.

siteseer Posted July 1, 2017 Share Posted July 1, 2017 Yeah, it's Scapanorhynchus for sure. Sand tigers of that area and time just don't get that big. It would guess it's from the Point Lookout Sandstone which is well-known for bearing shark teeth - abundant in at least a couple of sites - but only because I don't know of any occurrences of shark teeth in the other layers you noted (shark teeth certainly come out of the Mancos Shale in at least Colorado and Utah).
