QuestingFossils Posted July 13 Share Posted July 13 (edited) As in the title I started off my guess with this being Auriculatus. After doing a double take and researching potential IDs with what appears to be serrated cusps, but looking more at it why would it have striations if it is one and the weird serrated cusps and lack of serrations on the rest of the tooth? Another guess a friend of mine brought up was a type of sand tiger shark tooth cause of the striations and the nutrient groove. Any thoughts, help, input on the ID for this tooth are very much appreciated in advanced. Can and will take more photos later when I return to the homestead with any more physical info required to narrow down the shark.

sixgill pete Posted July 13 Share Posted July 13 First question is where in N.J. was this found? What formation? It is not an Otodus auriculatus. If Cretaceous possibly Anomotodon toddi. If Paleocene or Eocene possibly a Stiatolamia species. I do not think this is a Miocene tooth. 1 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...

Found in Lower member of the Kirkwood formation; contacting near the Vincentown formation. Definitely does remind me of some Cretaceous teeth I have but I think I can rule that out for the most part. 🤔 and with narrowing down most likely not Miocene. Could this tooth have been from the Paleocene/Eocene then worked it’s way and forming into a lag deposit? 1 Link to comment Share on other sites More sharing options...
njcreekhunter Posted July 13 Share Posted July 13 This is a well preserved example of a lateral Carcharias cuspidata. Miocene in age. 1 1 Link to comment Share on other sites More sharing options...

After seeing the response and where it was found, I agree with Carcharias. Could it be autissima?

Is there any way it can be an Isurus Desori that’s well preserved instead, I was going through some fossil stuff on the web today and stumbled upon this example that’s not as well preserved and strikingly similar now that I give it another look. Also what is the reasoning of it being a Carcharias cuspidata to look out for when IDing them?
