Etymology: Terrible Galerix, Galerix being a genus of hedgehogs.
About: Deinogalerix was a giant hedgehog. It was a carnivore, eating insects, snails, small mammals, reptiles, and birds. It was hunted by Tyto gigantea, a giant barn owl. It lived in what is now Italy. The place it lived was probably an island as that is where it is exclusively found along with a few other things.
