Glyptodontopelta was a slow, tank-like dinosaur covered in bony armor. It lived in what is now New Mexico, USA, during the very end of the Age of Dinosaurs. This plant-eater used its tough shield to protect itself from hungry predators.14

Fun facts

1

Glyptodontopelta is known mostly from its bony armor plates, called osteoderms. The most complete specimen includes over a hundred of these plates.1

2

Its name means 'Glyptodon shield' because its armor reminded scientists of the giant armadillo-like mammal Glyptodon.1

3

This dinosaur lived about 69 to 66 million years ago, right before the big extinction that killed most dinosaurs.1

4

For a while, some scientists thought Glyptodontopelta might be a fake name (nomen dubium), but later studies showed its armor is unique enough to be a real dinosaur.1

5

Another armored dinosaur from New Mexico, Edmontonia australis, is now considered the same animal as Glyptodontopelta.1
