An ancestor to modern armadillos, this armored mammal stands 5 feet tall and has a spiked tail it uses like a mace!

Doedicurus is a glyptodont, a prehistoric family of giant armadillos. In fact, it's the largest glyptodont to ever live!

Fossils of some Doedicurus shells show fractures consistent with their tails! This means they duelled each other!

It's possible Doedicurus store energy and liquid inside a hump under their dome, just like a modern camel!
