Thank you Shellseeker and MarcoSr. They are ray denticles. Mine look almost ray-denticle (I couldn't resist) like the two you have. The one that remains without comment is this one, which I have taken front and back pics. It is very small, round and concave.attachicon.gifimage.jpgattachicon.gifimage.jpgattachicon.gifimage.jpg

I hope these other pics help.

This may be part (top or bottom) of a fish or shark vertebra.

That's exactly what that is; and it is shark.

Here's my little guy

Thanks JCB -- Your fossil is quite a bit thicker proportionally to the one I originally posted and helps me to add context to Rich's statement on identification

I believe you have may have an osteoderm of Pachyarmatherium leiseyi. It isn't as thick as some of them get to be, but seems thicker than most D. bellus (which is actually Propraopus bellus).

No problem Jack, it's neat seeing some more of these.That's the only one in my collection.

Every once in a great while it's not just a big rock down there!

I also had seen this link to the Florida MNH Vertebrate ID database to which has some great photos for Dasypus comparison.

They unfortunately dont have any comparitive link for Pacyarmatherium.

Thanks for all responses, and especially Rich -- I make assumptions on minimal data and as you might guess, I am frequently wrong. I thought that this fossil was Glyptodon.

I have these two recently ---

What are they?

EDIT: I did hunt today within 1 mile of Paynes Creek Park which is one of the few sites for Pachyarmatherium leiseyi. Just additional info Rich

Jack, I don't know if you got your answer but I purchased similar osteoderms. They were found in N. Florida, Pleistocene and he said they were Holmesina Septentrionalis, not Glytodon. Here is the pic.

This is a very interesting thread and covers many different, but related animals:  In the Peace River , we commonly find Glyptodon osteoderms and Armadillo osteoderms. The 2 animals are related.

This is generally agreed to be Gyyptotherium Floridanum: I have found these frequentlyup to the size of baseball.

This is Armadillo: You have many that look like this.  I find a lot of them.ArmadilloCM.JPG.ca02f930f145c1a1b6c9e8ff237874b0.JPG

The discussion in this thread is what is this fossil found near Payne Creek Park.  Is it Glyptodon or Armadillo ?  Turns out it is Armadillo... I am certain that my photo on the right matches your Armadillo scutes, but what about the photo on the left?.
