The hefty carnivore is the fourth large, predatory dinosaur discovered in Egypt's Bahariya Formation.
One of the world’s most dangerous prehistoric ecosystems just added another huge predator to its

lineup.

In the Bahariya Formation, a famous fossil site in Egypt’s Sahara Desert, a team of Egyptian and American paleontologists recently uncovered a huge fossil vertebra belonging to a newly described species of meat-eating abelisaurid dinosaur — a bipedal, carnivorous group that lived during the Cretaceous period (145 million to 66 million years ago). 

Like other abelisaurids, the newfound dinosaur had a shortened, bulldog-like face. And despite its ferocious appearance, this carnivore probably wasn’t the biggest, baddest boss to roam its stomping grounds.

"We’re about 99% sure that, unlike some of its relatives from other times and places, this particular abelisaurid was not at the top of its food chain," Matthew Lamanna, a paleontologist at the Carnegie Museum of Natural History in Pittsburgh and one of the researchers who discovered the dinosaur, told Live Science in an email.
