squali Posted September 30, 2017 Share Posted September 30, 2017 New Jersey campanian. Found this a while back and haven't been able to get a good grasp on it's ID. Of course when I first found It I thought it was a jaw piece with teeth. Yay! Then I put on my glasses. Hmm. The fish spines I've found aren't serrated. It's obviously split but maybe someone has seen this before. Any insight is greatly appreciated. Thanks Jeff Edited: I believe this to be an enchodus jaw section thanks to the folks answering below.

Macrophyseter Posted September 30, 2017 Share Posted September 30, 2017 Looks like a jaw. I might be seeing some teeth. If you're a fossil nut from Palos Verdes, San Pedro, Redondo Beach, or Torrance, feel free to shoot me a PM! Link to comment Share on other sites More sharing options...
squali Posted September 30, 2017 Author Share Posted September 30, 2017 They do have a tooth shape but there isn't much contrast or sign of enamel. Though I'm not sure.

ynot Posted September 30, 2017 Share Posted September 30, 2017 I agree with a sawfish rostrum piece. Darwin said: " Man sprang from monkeys."

The Jersey Devil Posted September 30, 2017 Share Posted September 30, 2017 Definitely not sawfish. I think it's an enchodus jaw section with teeth on it. Usually the teeth on jaw sections don't have enamel on them. It's kind of weird how the teeth are bunched up in the right end of the first pic though. It looks like it is complete or close to complete.

squali Posted September 30, 2017 Author Share Posted September 30, 2017 I should of checked with my scope first . They do appear to be teeth. I agree not sawfish. Enchodus is great with me. I wonder what a beat up barracuda dentition looks like. They appear conical at the base and some taper others appea more peg like at the base. thanks for the responses so far.

Fossildude19 Posted September 30, 2017 Share Posted September 30, 2017 I'm for Enchodus jaw. .

squali Posted October 1, 2017 Author Share Posted October 1, 2017 Thank you Tim, for your photo magic. The contrast was what I was looking for. I have found many enchodus parts but not a jaw like this. The cudda dentition I looked at had a similar base but tapered to a blade. Could you or I change the title to replace "spine" with "jaw" ? Thank you all for looking and helping me see. It's hard to remember why you drained the swamp when your surrounded by alligators. Link to comment Share on other sites More sharing options...
The Jersey Devil Posted October 1, 2017 Share Posted October 1, 2017 I think barracudas first appeared during the early Eocene, so this can't possibly be from a cuda. “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...
squali Posted October 1, 2017 Author Share Posted October 1, 2017 Edit: this statement is incorrect:-Actually there is recent otolith evidence from the campanian of barracuda in New Jersey, but I can't hope against the physical evidence, definitely not the same crown as these possible teeth. - It looks like fish bone so much that I can't convince myself that the conical shaped teeth are croc. I'm thrilled that it's probably another piece of my favorite fish of the Cretaceous. It's hard to remember why you drained the swamp when your surrounded by alligators.

And in the end it was sitting high and proud on top of an exposed, tiny piece of the formation. waiting patiently. It's hard to remember why you drained the swamp when your surrounded by alligators.

Does that mean there is a chance to find Barracuda teeth in the late cretaceous streams of nj? Or does it have to be some later formation that is latest cretaceous? “You must take your opponent into a deep dark forest where 2+2=5, and the path leading out is only wide enough for one.” ― Mikhail Tal Link to comment Share on other sites More sharing options...
squali Posted October 1, 2017 Author Share Posted October 1, 2017 My apologies I am mistaken regarding Sphyraena ( barracuda) being identified in the campanian. To date none have been found.

MarcoSr Posted October 1, 2017 Share Posted October 1, 2017 It is always difficult to id specimens from pictures. Plus it is always best to consider the most common ids first. If you aren't 100% convinced on Enchodus jaw there are some other possibilities like a fragment of a Chimaeroid dorsal fin spine or Hybodus fin spine. But usually the common possibility is the correct one. Marco Sr. "Any day that you can fossil hunt is a great day."

squali Posted October 3, 2017 Author Share Posted October 3, 2017 As a follow through I did check the fossil piece against what I could find regarding the Chimaeroid and Hybodus. More evidence that is Enchodus. would anyone care to speculate whether this would be a juvenile? The robustness of the 'fang' of some specimens I have seem way out of proportion to this dentition. I do have many small frontals on the order of 5-7mm. So it's probable? It's hard to remember why you drained the swamp when your surrounded by alligators.

Carl Posted October 4, 2017 Share Posted October 4, 2017 I agree: Definitely a fish jaw. Looks like all the jaw fragments I have that have been IDed as Enchodus. Link to comment Share on other sites More sharing options...
