An article published in the journal “PeerJ” reports the identification of a new species of carnivorous dinosaur that lived between 152 and 157 million years ago, in the Jurassic period. Daniel Chure and Mark Loewen named it Allosaurus jimmadseni after examining various fossils discovered in the 1990s in Utah and Wyoming to determine that it’s a new species of allosaurus, a few million years older than the first one discovered, Allosaurus fragilis. The differences between the two species suggest different eating habits.
