Megaselachus13 Posted July 9, 2008 Share Posted July 9, 2008 It might be from a paleozoic shark. Seems to a Godzilla version of some Peripristis teeth. Undoubtedly is a monster size to those times. Cool tooth. Link to comment Share on other sites More sharing options...
MOROPUS Posted July 9, 2008 Share Posted July 9, 2008 It took some research but after I found out what it is it became my 2nd favorite fossil to get .... can you ID the tooth .. btw it is about 3.25" across (left to right). It reminds me a beardog molar side view,but aswell to other mammal molar, like Meles Meles, or just a pathological one of somekind of carnivorous .Can you rotate it, so we can se de upper part or the other view?

MOROPUS Posted July 9, 2008 Share Posted July 9, 2008 Here is once side view and a semi side view/top view (you can see the back of the tooth). A pulmonate upper pharingeal tooth? A lamprey pharinx tooth? The top view has just me! Does`t look mammal,thoug the type of bone attached to it looks as it is... Link to comment Share on other sites More sharing options...

isurus90064 Posted July 9, 2008 Author Share Posted July 9, 2008 That's it Chupacabra :P You guys are in the correct corner of the animal kingdon. ... this tooth is from a Permian shark. Question is which one .. I was going to let it run until Saturday and see if anyone was able to come up with an ID.

Mike Murphy Posted July 9, 2008 Share Posted July 9, 2008 Isurus90064: That is one gorgeous specimen! The tooth looks to be from a Peripristis (Ctenoptychius) sp. (possibly Peripristis semicircularis), which is known from the Pennsylvanian and Permian rocks of Texas, Oklahoma, New Mexico, Kansas and Nebraska. If it is, it is an enormous tooth. I have specimens from the Belle City Limestone (Pennsyvanian) and Boggy Formation (Pennsylvanian) in Oklahoma and from the Colony Creek Shale (Pennsylvanian), Lake Bridgeport Shale (Pennsylvanian), Harpersville (transitional Pennsylvanian to Permian) and Leuders Formation (Middle Permian). The teeth that I have collected have ranged from about one half inch up to one inch in length. Regards, Mike Link to comment Share on other sites More sharing options...
hybodus Posted July 9, 2008 Share Posted July 9, 2008 Hmmm... @ 3.25" wide... the ony Paleozoic shark teeth I know of that reach that size belong to the Petalodonts. My guess is Megactenopetalatus kaibabanus. Can you tell me the locality it was collected from? The only thing I have close in size in a Paleozoic tooth is a Petalodus: 52mm height, 56mm width - and yes, it is red! On a seperate note - we need to synch up at some point - looks like we share an interest in cool and unique shark remains! Link to comment Share on other sites More sharing options...
hybodus Posted July 9, 2008 Share Posted July 9, 2008 BTW Isurus - is the tooth in your collection? Link to comment Share on other sites More sharing options...
Guest bmorefossil Posted July 9, 2008 Share Posted July 9, 2008 BTW Isurus - is the tooth in your collection? im gonna second the Megactenopetalatus the closet i found and anyting with mega in is name is good choice. No i think when he said its his second favorite fossil he would like to get , he hasnt found it yet,but i guess he could have, isurus has found everything Link to comment Share on other sites More sharing options...
worthy 55 Posted July 9, 2008 Share Posted July 9, 2008 Very cool!!! I have seen a tooth like that but can't remember what it came from but still cool ! It's my bone!!! Link to comment Share on other sites More sharing options...
isurus90064 Posted July 9, 2008 Author Share Posted July 9, 2008 i have a question, is the tooth whole? Hey, the tooth is whole except for a small portion of bone that's missing at the bottom.

isurus90064 Posted July 9, 2008 Author Share Posted July 9, 2008 Hey Hybodus (and bmore :-)), I'm impressed!!!! It is the Permian petalodont chondrychthian named Megactenopetalus kaibabanus from the Kaibab Formation. This particular example is not in my collection, it resides in the Museum of Northern Arizona in Flagstaff. I do have one partial and several fragments of this species from a different location however. The locality on this specimen is the northern rim of the Grand Canyon not too far from Point Sublime. btw Hybodus, that's an absolutely beautiful Petolodus tooth!!!!

Guest bmorefossil Posted July 9, 2008 Share Posted July 9, 2008 it was really hard becuase the only info i could find on them was off of oceans of kansas, and i couldnt find any pictures on there but the description of the teeth fit this tooth Link to comment Share on other sites More sharing options...
hybodus Posted July 9, 2008 Share Posted July 9, 2008 Thanks Isurus... I have a huge collection of Paleozoic shark remains (my favorite), and I remembered seenig a reference to this form in Zangerel's Chondrichthyes I, Paleozoic Elasmobranchii - I double checked before supplying a response - page 96, figure 108 - although the poor line prawing shows a tooth roughly 65mm wide, Megactenopetalus is the only known Paleozoic tooth described so far to reach such a large size - That is an absolutely killer specimen you show, and I have added it to my want list!

isurus90064 Posted July 9, 2008 Author Share Posted July 9, 2008 And thanks - the Petalodus is from Washington County, Arkansas, Pitkin Limestone Formation. Very very nice indeed. I'll see if I can dig up my Megactenopetalus and photograph it although I have to find it in my garage first.

PaleoRon Posted July 9, 2008 Share Posted July 9, 2008 Monster tooth. It makes the two Petalodus teeth I found in Kentucky seem tiny. Link to comment Share on other sites More sharing options...
