Glyptotherium

Glyptodont

Glyptotherium is the North American glyptodont, an armadillo relative the size of a small car, whose carapace was made of thousands of hexagonal, rosette-patterned scutes that are common finds in Florida rivers and Texas gravels. Single scutes are cheap and unmistakable; articulated carapace sections are valuable. Scutes are often confused with those of the smaller Holmesina (pampathere), which are rectangular and pitted.
