Living about 126 to 127 million years ago, the bipedal dinosaur, named Protathlitis cinctorrensis, was about 33 to 36 feet (10 to 11 meters) long and weighed about 2 tons.
It was part of a group called spinosaurs whose biggest member, Spinosaurus, was among the largest meat-eating dinosaurs on record.
Spinosaurs lived in Europe, Africa, Asia and South America during the Cretaceous - the last of the three chapters of the age of dinosaurs.
Spinosaurus, about 50 feet (15 meters) long and weighing seven tons, lived 95 million years ago in Africa.
Unlike Protathlitis, Spinosaurus possessed unserrated teeth - better to capture slippery aquatic prey.
