erose Posted August 7, 2012 Share Posted August 7, 2012 What is it being billed as? Complete or partial reproduction? Price seems high either way. Link to comment Share on other sites More sharing options...
Jyonts12 Posted August 7, 2012 Share Posted August 7, 2012 The listing is for a complete set of teeth. It is for a museum display showing all real megalodon teeth. Price is high though. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&_trksid=p4340.l2557&hash=item45ffcb575f&item=300644259679&nma=true&pt=LH_DefaultDomain_0&rt=nc&si=bP3%252B9ktC2Qm0INsyeBhntjgFOao%253D&orig_cvip=true&rt=nc#ht_13010wt_978 Link to comment Share on other sites More sharing options...
PrehistoricFlorida Posted August 7, 2012 Share Posted August 7, 2012 The teeth are real, the jaw they're in is not. www.PrehistoricFlorida.com Link to comment Share on other sites More sharing options...

Down under fossil hunter Posted August 8, 2012 Share Posted August 8, 2012 I had been watching that set of jaws, interesting to search ebay by price and look at some of the fossils people put up. Link to comment Share on other sites More sharing options...
Carcharodontosaurus Posted August 8, 2012 Share Posted August 8, 2012 The feedback isn't exactly the best. I wouldn't bid on it. Has a real meg jaw ever been found? Link to comment Share on other sites More sharing options...
PrehistoricFlorida Posted August 8, 2012 Share Posted August 8, 2012 Has a real meg jaw ever been found? No. Fossilized shark jaws are not found as they are composed of cartilage. www.PrehistoricFlorida.com Link to comment Share on other sites More sharing options...
Carcharodontosaurus Posted August 8, 2012 Share Posted August 8, 2012 No. Fossilized shark jaws are not found as they are composed of cartilage. Aren't the jaws partially ossified? Link to comment Share on other sites More sharing options...
Coco Posted August 8, 2012 Share Posted August 8, 2012 Hi, Aren't the jaws partially ossified? No ! it exists 2 sorts of fish : 1- cartilaginous fishes : rays / skates - sharks and chimaeras (ratfishes) = chondrichtyens = selachians 2- osseous fishes (all other fishes). Cartilaginous selachian skeleton are in cartilage, contrary to the other fishes all the bones of which fossilize more easily. The cartilage is a supple material for which are needed conditions so special to be able to fossilize that that arrives only very very rarely.

Jesse Posted August 10, 2012 Share Posted August 10, 2012 No. Fossilized shark jaws are not found as they are composed of cartilage. Not entirely true, some types of sharks have partially ossified jaws that can be preserved. I have seen a few papers illustrating this and have seen it personally, not on a meg though...

Coco Posted August 10, 2012 Share Posted August 10, 2012 Jesse, you can see a part of fossilized jaw on the 1st page of a Dirk Nolf book, but it rarest. Does it mean it was ossified ? If you have documents on the partial ossification of shark jaws, that interests me.

Auspex Posted August 10, 2012 Share Posted August 10, 2012 Still, fossilized shark jaws are fragmentary and vanishingly rare; a complete, undistorted 3-D jaw (like the example that founded this thread) is (dare I say it?) a practical impossibility.

But it still makes one wonder if there is a completely ossified meg jaw out there...somewhere...waiting...

Jesse Posted August 17, 2012 Share Posted August 17, 2012 Coco, I was recently corrected by a colleague, shark jaws with rigid structures are calcified, not ossified. I work almost exclusively in the Paleozoic so i see quite a bit of jaw preservation, sharks trended toward less calcified jaws after the end Permian extinction. Auspex, I think you are correct a meg jaw like above is impossible, would not happen. Would be super amazing though! Coco, pm me your email adress and i will try and send you a few papers, some of them are huge files and may exceed email restrictions. Link to comment Share on other sites More sharing options...
