Glyptodont Osteoderm

A beautiful little glyptodont osteoderm! I'm not familar with what species existed in Texas during the late Pleistocene, but this looks a lot like the early Pleistocene Glyptotherium arizonae that we find here in Florida.

I thought arizonae was synonymized with texanum?

Interesting! I checked the FLMNH vert paleo database and it does seem that they began labelling new early Pleistocene Glyptotherium as G. texanum sometime after that paper was published as well. I guess it's time to change my labels on some fossils. I appreciate the heads up.
