jamhill Posted December 16, 2020 Share Posted December 16, 2020 Found these on the beach in Jacksonville Florida so Pleistocene. They appear to be some kind of scute. Are they glyptodont edge scutes? Tortoise leg spurs maybe? The first one looks like two fused together. One in the second group doesn’t actually come to a point but is otherwise very similar. 2 Link to comment Share on other sites More sharing options...

Maybe @Shellseeker will be able to tell the difference between the Giant Tortoise and Glyptothere osteoderms ? To my eyes they always look so similar. Very cool finds btw ..

Cheers, B WoW!!!!! 12 years hunting and I have found exactly 1 double: http://www.thefossilforum.com/index.php?/topic/95243-another-place-to-avoid-bartow/ Turtles /Tortoise have both leg spurs and foot pads. You have found 3 Spurs and 1 foot pad which is the roundish one. Glyptodont osteoderms are pretty much unique. Nothing looks like the body ones: The Glyptodont tail osteoderms are somewhat similar to turtle/tortoise spurs. but I think they looks more like a Hershey Kiss See this thread -- it is really good. 4 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
Plantguy Posted December 16, 2020 Share Posted December 16, 2020 Nice finds Jamhill and Jack! I am curious about both of your finds. What does the side/opposite surfaces of those look like? Jamhill Is the 2nd photo a side view? Thanks! Regards, Chris 1 Link to comment Share on other sites More sharing options...

Sacha Posted December 16, 2020 Share Posted December 16, 2020 The double one is one half of a giant tortoise hinny binder. Merk Renz's book "Fossiling in Florida has one. Look on page 131for a picture. I no longer have the book. 2 Link to comment Share on other sites More sharing options...

Regards, Chris Sorry Chris, I just went back to find it in my photo Gallary, but did not take the photo of the bottom and it is unfortunately "lost" in my collection of 1000s of fossils. It was found in one of my rare trips to Bartow in November, 2014. 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

Plantguy the second pic is a side pic and here are some bottom pics Jamhill, Thanks for the additional photos. I've been working with alot of turtle/tortoise fragments recently and that 1st find of yours caught my eye, as I have something similar in shape sitting on my table at the moment. Yours does look to be an osteoderm though. I would like to see what Mark Renz has imaged...If that one is of the buckler types of osteoderms?. So here's some photos of what I have here on the table that made me wonder. I've been told its a juvenile chelydrid (snapping turtle) posterior peripheral--part of the back of the shell/carapace...At certain angles it vaguely resembles yours but the details are definitely in the surface textures and side views which are definitely unlike yours. It also shows a small indentation/hole that is a rib insertion point... Thanks again for making what I had on my table clearer in my mind! Maybe I can now put the darn thing away...LOL... Again nice finds! Regards, Chris 1 Link to comment Share on other sites More sharing options...

My latest insanity is taking apart an extant Trachemys turtle carapace to look at the different views/cross-sections of the shell elements and trying to match/compare them against the fossil turtle pieces...Call me crazy as I am! Nice find--congrats on that one--- many years too late! Regards, Chris 1 Link to comment Share on other sites More sharing options...

This is an interetsing find and I also have seen shapes like your photo #1, but never knew what it was.... I will recognize it going forward, and get/keep the next one I see.
