Auspex Posted January 1, 2009 Share Posted January 1, 2009 Not at all common, but I have seen it. Notice that it's not just the enamel!

worthy 55 Posted January 1, 2009 Author Share Posted January 1, 2009 Yes, it has it in the root on both sides a little also. It's my bone!!! Link to comment Share on other sites More sharing options...
Auspex Posted January 1, 2009 Share Posted January 1, 2009 Whether that constitutes a pathology depends on your definition of "pathology". (I tend to think of it as a deformation caused by trauma or disease).

Guest bmorefossil Posted January 1, 2009 Share Posted January 1, 2009 yes and this would just be a growth thing not what i would call a pathology Link to comment Share on other sites More sharing options...
worthy 55 Posted January 3, 2009 Author Share Posted January 3, 2009 I also found the same thing on one of my GW teeth. It's my bone!!! Link to comment Share on other sites More sharing options...
Auspex Posted January 4, 2009 Share Posted January 4, 2009 Why are you keeping that wrinkley old thing? Since you deserve better, and I don't, send it to me "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

tracer Posted January 4, 2009 Share Posted January 4, 2009 has that characteristic been noted in modern great whites? Link to comment Share on other sites More sharing options...
worthy 55 Posted January 4, 2009 Author Share Posted January 4, 2009 Tracer, I don't know but maybe some one on the forum can help ? I would like to know myself. It's my bone!!! Link to comment Share on other sites More sharing options...
Guest bmorefossil Posted January 4, 2009 Share Posted January 4, 2009 I also found the same thing on one of my GW teeth. i think its more common on the back of the teeth for some reason Link to comment Share on other sites More sharing options...
Cole20200 Posted January 10, 2009 Share Posted January 10, 2009 I've got a few teeth with that kind of 'pathology' too. I'd be very interested to know if it manifests in modern sharks. And if it does, what is the cause. It could end up meaning anything from prey habits too age of individual, or just some kind of anomaly in the tooth's creation, sharks are after all tooth factories. Fossil, it's like a rock, but better. Link to comment Share on other sites More sharing options...
Northern Sharks Posted January 11, 2009 Share Posted January 11, 2009 Several of my teeth have these wrinkles as well, both Mako and GW. With 1 exception, the ridges are on the back (labial) side and it seems to only be on the larger teeth. That being said, I also have large teeth with no wrinkles. The only modern GW I have does show some sign of the wrinkles, but not as dramatic as on the fossils. 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...
Guest bmorefossil Posted January 11, 2009 Share Posted January 11, 2009 yes they are not on every tooth and I think I said this already they seem to be on teeth over 2", for some reason I have more teeth with the wrinkles on the back than the front, I alson have some teeth that have wrinkles just on the tooth or just on the root. These teeth are usually smaller than 2", this might show that they grow into a tooth that has the wrinkles on booth. Link to comment Share on other sites More sharing options...
worthy 55 Posted January 12, 2009 Author Share Posted January 12, 2009 Well I guess someone needs to do a study on why these teeth get the wrinkles huh. Very interesting! Thanks for the input guys. It's my bone!!! Link to comment Share on other sites More sharing options...
Guest bmorefossil Posted January 12, 2009 Share Posted January 12, 2009 yea ill be going through my teeth tonight to see what i can find with the wrinkles, hey if we can get enough together we might be able to create a theory Link to comment Share on other sites More sharing options...

Yes, that it good to take into consideration. A number of people have mentioned that these occur in larger sharks. I would assume that larger sharks mean larger prey. Large prey require more jaw extention to bite and swallow. Remember sharks jaws are made from flexible cartilage. Teeth that would just be forming could receive a bit of a squeeze from the jaw extending and other teeth pushing them together. Just a hypothesis The soul of a Fossil Hunter is one that is seeking, always. Link to comment Share on other sites More sharing options...
tracer Posted January 12, 2009 Share Posted January 12, 2009 that's an interesting hypothesis. i've been wondering about this and trying to figure out how enamel forms in a "rippled" manner without cracking - guess i'd better go research enamel formation some...

Just a hypothesis i think it has something to do with the teeth as they are moving into position, the shark is going to be growing and teeth are going to be filling in as teeth fall out, i think if a tooth moves into place as it is still growing it causes this wrinkle in the tooth.

Sharktoothguy11222 Posted January 12, 2009 Share Posted January 12, 2009 I was thinking that it could be the "age factor", if there is such a thing, with the wrinkles on sharks teeth. Now, some on this topic have stated that some large teeth don't have wrinkles and some do. Perhaps(and don't yell at me ), wrinkles only form in larger, more older specimens only. Juvenile, or other sharks still in their prime, I suppose, would produce fairly large teeth, but would not be old enough to form the wrinkles. P.S. Just an idea. Tha tighin fodham, fodham, fodham!

Guest bmorefossil Posted January 12, 2009 Share Posted January 12, 2009 lol they are all just ideas, no one is right no one is wrong, just something to get people thinking. Link to comment Share on other sites More sharing options...
Harry Pristis Posted January 12, 2009 Share Posted January 12, 2009 Not at all common, but I have seen it. Notice that it's not just the enamel! Wrinkles occur in a number of species, and are diagnostic in Isurus retroflexus, Cretodus borodini, and Palaeogaleus vincenti, for examples from Kent. Kent describes the I. retroflexus condition as "short vertical wrinkles along basal margin of labial coronal surface." Of course, Kent is describing wrinkles in the enameloid of the crown. What makes Worthy's teeth interesting are the wrinkles extending beyond the crown into the root. 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...
Guest bmorefossil Posted January 12, 2009 Share Posted January 12, 2009 i find it odd that I have teeth with wrinkles in the root and in the crown, not both. I wonder why Link to comment Share on other sites More sharing options...
MOROPUS Posted January 14, 2009 Share Posted January 14, 2009 Could it be a carential of some kind? I`ve read about the wrinkles and signs on human and predatory mammal tooth (both extinct and extant), as a leakeage of some proteins/vitamins.Famine sometimes? Egg period famine? Could it be that, as they were so big, and the preys have to be aswell very big, they must be less number of preys? Perhaps, this fishes must have stay a loooooong time feeding on smaller preys (without good source of vitamin-protein), or even without eating from time to time. This can be my theory.
