Glyptodon
The Glyptodon were relatives of the armadillos that lived during the Pleistocene epoch. Surprisingly, these extinct animals were the size of a Volkswagen Beetle, weighing up to 1,850 pounds. It had squat limbs and a round, bony shell. It resembled the modern day turtle, and roamed the lands of North and South America. Their body shell alone was five feet. You wouldn’t want to mess with the Glyptodon, as their tails were equivalent to a lethal club. They devoured almost anything, including plants and insects (Wikipedia).
