MikeD Posted August 27, 2009 Share Posted August 27, 2009 Sent your pic to my contact at the local museum. He says, "it is a type of requiem shark and the weathered form is what makes it look rather odd. The tip has worn off, but the lateral serrations are still present. Take a common tooth from stone city, a hammerhead or a bull or a blue and wear down the tip so that just the lateral edge is present and that’s what you are seeing here. Probably occurred from tumbling." Link to comment Share on other sites More sharing options...
Uncle Siphuncle Posted August 27, 2009 Author Share Posted August 27, 2009 Thanks Mike. This probably is Stone City rather than Cook Mountain now that I've talked with some folks. Grüße, Daniel A.

Northern Sharks Posted August 27, 2009 Share Posted August 27, 2009 It looks to me like a worn Galeorhinus (Tope shark). I would have to check my info and see what types could be found down there. There's no limit to what you can accomplish when you're supposed to be doing something else Link to comment Share on other sites More sharing options...
Hieronymus Posted August 27, 2009 Share Posted August 27, 2009 It looks to me like a worn Galeorhinus (Tope shark). I would have to check my info and see what types could be found down there. Indeed, might be Galeorhinus, could also be a Physogaleus secundus, which is not an uncommon find in eocene deposits. It's just very worn. http://rhaetianlorraine.webs.com/ Link to comment Share on other sites More sharing options...
