-AnThOnY- Posted March 1, 2011 Share Posted March 1, 2011 Found this about 10 years ago and have always wondered what it was, when I found it I thought it was some kind of talon or something, but now I am thinking fish tooth? The disk is about 4mm with the "tooth" being around 5 for whatever reason photo-bucket wouldn't let me upload the other pic but hopefully this is good enough Thanks much Link to comment Share on other sites More sharing options...
DeloiVarden Posted March 1, 2011 Share Posted March 1, 2011 I have no clue, but it is interesting. My vote is an old shark. Do you know what the epoch of the material was (Eocene, Miocene, etc.). Link to comment Share on other sites More sharing options...

-AnThOnY- Posted March 1, 2011 Author Share Posted March 1, 2011 I have no idea of the age. I was 10 when I found it. But shark would be interesting I guess I will have to do some more research and see what happens. Link to comment Share on other sites More sharing options...
-AnThOnY- Posted March 1, 2011 Author Share Posted March 1, 2011 Is it round? Whatever it is, it's very cool! Yeah the top portion is round and its a tubular tooth not flat on the back like a shark tooth Link to comment Share on other sites More sharing options...

Harry Pristis Posted March 1, 2011 Share Posted March 1, 2011 Where did you find it? What did you find with it? The tooth reminds me of a ray tooth. http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
-AnThOnY- Posted March 1, 2011 Author Share Posted March 1, 2011 Were found with stingray pieces, and miscellaneous shark teeth (sand tiger, tiger, bull, dusky, lemon). If indeed stingray, any idea on sp? or somewhere I can figure out? Link to comment Share on other sites More sharing options...

Bill Posted March 1, 2011 Share Posted March 1, 2011 (edited) Being found with those sp. I'm more in the 'dermal denticle' corner now.

-AnThOnY- Posted March 1, 2011 Author Share Posted March 1, 2011 (edited) Not really fitting much I see from ray denticles, but I would say your pic is close but doesn't appear that any of your (except the recent one) have a point like end or "enamel" on the point at that. The closest thing I found google searching was a picture from MB on here that was a batoid dermal denticle (ray) but even that looks different. Not sure. I guess I'm probably expecting something to look exactly the same when I probably wont get that. Edited March 1, 2011 by -AnThOnY- Link to comment Share on other sites More sharing options...

I guess I'm probably expecting something to look exactly the same when I probably wont get that. The Raja denticles do vary across the body. The Hypolophodon sylvestris ones are from the Early Eocene, A lot of them are worn to some extent, and are from a Guitarfish. I don't think they were like yours, but the Raja is similar. The pic' simply shows a couple of denticle designs. There are pic's of other sp. denticles on the forum. Edited March 1, 2011 by Bill KOF, Bill.

Auspex Posted March 1, 2011 Share Posted March 1, 2011 These pics strengthen my feeling that it is a dermal denticle.

Coco Posted March 2, 2011 Share Posted March 2, 2011 Anthony, I cannot really help you to identify your fossil. It is true that the "sharp" of the dermic denticules of rays are made the same material as the selachian teeth. Bill, I can specify that the position of your Raja clavata denticle is under the body of the ray, either around the mouth, or around the anus. The denticules of the top of the body is different. It could be interesting that I made a subject on the dermic buckles of the current lines which I have in collection, but it is often small and I have at present no correct photo. But if that interests you, I can make the work (I just nedd some time). Auspex, your link is very good !
