Cole20200 Posted January 16, 2009 Share Posted January 16, 2009 We've uncovered a deep shark mystery here folks. Be careful who you speak with about this...who knows how high up this goes? The wrinkles by also have something to do with tooth shape and use, I'd be interested to see what position the teeth are in that get the wrinkles. Fossil, it's like a rock, but better.

tracer Posted January 16, 2009 Share Posted January 16, 2009 i kinda wondered if it was like an auto-sizing function or something to keep growing teeth from having too much lateral crowding in the jaw or something. keep the rows all straight and everything. you know, "oops! our lobes touched! excuse me - i'll just wrinkle a bit until i can get the growing halted." some kinda dentin courtesy thing.

Boesse Posted January 16, 2009 Share Posted January 16, 2009 I've actually got a lot of Isurus hastalis, Isurus planus, and Carcharodon teeth with wrinkles; makes sense, as they're all fairly closely related. Bobby Link to comment Share on other sites More sharing options...

Guest bmorefossil Posted January 16, 2009 Share Posted January 16, 2009 and i just remembered i posted a topic awhile ago on how my giant thresher had these, someone actually had a name for it. Link to comment Share on other sites More sharing options...
Guest bmorefossil Posted January 16, 2009 Share Posted January 16, 2009 Bill was the one to say something, here is the topic: http://www.thefossilforum.com/index.php?sh...l=giant+tresher Link to comment Share on other sites More sharing options...
Bill Posted January 16, 2009 Share Posted January 16, 2009 Just caught up with this thread. Crenulations are also very common on juvenile teeth, intermediate and posterior, and adult Striatolamia teeth, among others. The grubby yellow tack is less sticky than new stuff. KOF, Bill.

Guest bmorefossil Posted January 17, 2009 Share Posted January 17, 2009 so you think its an age issue? Then why can it be seen in larger makos and such? Link to comment Share on other sites More sharing options...
Bill Posted January 17, 2009 Share Posted January 17, 2009 No idea, but I did include Adult, above. I don't recall seeing it on medium sized Striat' teeth, but you can certainly find it on small and large ones. With regards to large teeth, I've only seen it on posteriors. I'll have a look through my teeth later. (For Tracer, "---my teeth" refers to my collection of shark teeth) KOF, Bill. Welcome to the forum, all new members www.ukfossils check it out.

Guest bmorefossil Posted January 17, 2009 Share Posted January 17, 2009 so you can find it on your larger posterior teeth but on makos its any teeth, i find that interesting as well Link to comment Share on other sites More sharing options...
tracer Posted January 17, 2009 Share Posted January 17, 2009 (For Tracer, "---my teeth" refers to my collection of shark teeth) well, ok, bill, but if i were you, i wouldn't look "through" your teeth later. if you look at your teeth rather than through them, you're more likely to see that which you wish to see. gotcha! and it's not even literal thursday!

Guest bmorefossil Posted January 17, 2009 Share Posted January 17, 2009 come on! you should know by now that Bill has x-ray vision (im sure he uses for stuff other than fossils ) so when he looks through the teeth he can see the crenulations without moving a tooth!!! I wish I could do that. Link to comment Share on other sites More sharing options...

Bill Posted January 17, 2009 Share Posted January 17, 2009 Unfortunately both of these Striat' teeth are broken, so I don't know how big they would have been. They would have been a fair size though. The field of view is 10mm. The crenulations don't show up as well in the pic's as in the hand. KOF, Bill. Welcome to the forum, all new members www.ukfossils check it out.
