Shellseeker Posted May 3, 2015 Share Posted May 3, 2015 I am walking gingerly today. Three outings (with different hunters each) the last 3 days. Peace River above Wauchula where I posted an ID that may be rare smaller camel m3, Myakka River above Rocky Ford, where I had engine trouble and paddled back with 1 paddle and 1 shovel, and yesterday back to the Peace River. We found a lot of well preserved small shark teeth at Myakka and I found a kogiopsis .sp tooth in what seemed like a dominate marine layer. Lots of fossil shells. Saw a real LARGE gator in a really narrow point of the river. My hunting partner and I only disagreed on how much bigger it was than my 12 foot canoe. Sorry I did not get a photo of the gator but I had other things on my mind. Saturday was the most productive. Found a small area not previously dug that produced interesting finds. I do not find many lower makos. Is this mako Hastalis? Ah.. This is an ID thread. I was disappointed to see the damage to the chewing surface and thought maybe horse, maybe camel. Then it occurred to me that I had never seen a horse or camel with side ribbing like this and maybe someone would be able to ID on what is left on the chewing surface. Ok!! All the photos fit in 2mb!! As always comment and help in ID appreciated.

RichW9090 Posted May 3, 2015 Share Posted May 3, 2015 Looks to be a glyptodont tooth. The plural of "anecdote" is not "evidence". Link to comment Share on other sites More sharing options...
Shellseeker Posted May 3, 2015 Author Share Posted May 3, 2015 Rich, Thanks for the reply. I momentarily wondered if the chewing surface was Glyptodont, but then rejected based on the small size just over an inch. The only Glyptodont tooth I had ever seen was in this post from Perico. http://www.thefossilforum.com/index.php?/topic/39821-glyptodon-tooth/ I think of Glyptodonts as the size of a 1968 VW . Is there a smaller version? The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
jlar7607 Posted May 3, 2015 Share Posted May 3, 2015 Man that sure is a sweet lower mako big and beefy ! So you found a glypto congrats jack I guess this puts you back ahead of me ! :-( Link to comment Share on other sites More sharing options...

Shellseeker Posted May 4, 2015 Author Share Posted May 4, 2015 They had to be born small... Yes, that is true. I have sent the photos to RIchard Hulbert. I guess it is good that I am using him more and more. It means I am finding interesting fossils. Also on the Mako, http://www.thefossilforum.com/index.php?/gallery/image/141-isurus-desori-extinct-mako-shark/, I wonder if it might be Isurus Desori - Mark Renz in Hunting the Hunter pg 100 shows one found in the Caloosahatchee River which is south of the Peace River. The root is too messed up to determine whether it has a nutrient pore or not.

RichW9090 Posted May 4, 2015 Share Posted May 4, 2015 Juvenile glyp teeth are very rare - Our research site in eastern Arizona has produced more glyptodonts than any other site in North America; we have a couple of very small glyps which were close to neonate, but no skull or teeth.

jlar7607 Posted May 4, 2015 Share Posted May 4, 2015 louis says glypto %100 certainty he has a jaw with teeth in it plus one closet full of nothing but glypto teeth !! Link to comment Share on other sites More sharing options...
fossilized6s Posted May 4, 2015 Share Posted May 4, 2015 Jack is still on his streak of rarity!! Keep it up, sir.

Rich, Your identification is exactly correct. ....It has oddly shaped buttresses, and although damaged seems some what like a glyptodont. However it is narrow and a little over an inch in height, so it seems inconsistent and too small to be glyptodont. Worth showing you in case I should send both for evaluation. Jack Yes, that is a glyptodont. It is from a “baby”. Glypotodonts, pampatheres, and sloths do not have deciduous (baby) teeth like other mammals. Instead their teeth (which are ever-growing) start small in size to fit their smaller jaws and gradually get larger. So when you look at them from the side, the sides of the tooth are not parallel. Once their teeth reach adult size, the sides of the teeth are parallel and it does not get larger from top to bottom. This is not unique to this particular group of mammals. Others with ever-growing teeth do this too, such as rabbits and the giant beaver Castoroides. Richard I am really pleased with this one. Very rare and likely the only one I'll have in my collection. I have discussed while hunting how I would love to find a Glyptodont tooth with the one in mind from Perico's TFF thread. These are extremely rare in the Peace River and I never expected a "baby". I was hunting with JLar7607 and did not even mention it to him because it looked broken and I did not recognize it. Incredibly lucky the last two months -- hope it continues!!

Perico Posted May 5, 2015 Share Posted May 5, 2015 Congrats buddy!!!! Welcome to the club! That is a great find. Be careful and preserve it soon they are very brittle. Link to comment Share on other sites More sharing options...
digit Posted May 5, 2015 Share Posted May 5, 2015 Unbelievable! Loving the diversity of unusual mammal dentition you are rescuing from the rivers. Just about completed my 44 hour transit back to the Maldives at the end of my last research mission. From here it is only a day and a half flying to get back to South Florida. Itching to break out the sifting screen and wade into a river (haven't been out all season yet). It's been an odd season with river levels but that sure hasn't stopped you and your epic parade of finds. Hope you've left a scrap or two for the rest of us to pick over. Cheers. -Ken Link to comment Share on other sites More sharing options...
Diceros Posted May 5, 2015 Share Posted May 5, 2015 Richard's right - your photo on the left shows that the tooth gets larger toward the right. The same is true of other juvenile edentate teeth. They really don't have a tooth crown, as they have no tooth enamel. The raised ridge you see in the occlusal view is a hardened dentine layer within the main tooth dentine. I'm surprised Richard didn't suggest a genus or species, as there are few glyptodonts in Florida. The common Pleistocene one is Glyptotherium floridanum (Simpson). Congrats, a rare find! In the top row of pics, I see a lw. ant. tooth of Cosmopolitodus hastalis (old "Isurus desori", from before they realized they were the same)(the "broad-toothed makos" have now been put closer to Carcharodon than to Isurus, so they had to put them in different genera), an up. ant.lat. of a Carcharhinus (maybe the bull shark C. leucas), an alligator (Alligator mississippiensis) tooth, and the epiphysis from the vertebral centrum of a small cetacean (dolphin?).
