"N. rex was a very robust and peculiar rabbit," project leader Josep Quintana told Discovery News. "Surely he was a very calm and peaceful animal that moved with slow, but powerful, movements."
Quintana, a scientist at the Catalan Institute of Paleontology, and colleagues Meike Kohler and Salvador Moya-Sola describe the giant fossil rabbit in a Journal of Vertebrate Paleontology paper. They believe the rabbit lost the ability to hop, because the long, springy spine typical of modern bunnies was replaced by a short, stiff backbone.
The researchers think N. rex spent most of its days peacefully digging, searching for roots and tubers to eat.
