Rex And First Dinosaur Known to SwimFossils paint the most complete picture yet of the ancient swamp creature's predatory life.National Geographic, Published September 11, 2014"The biggest and the baddest among meat-eating dinosaurs, Spinosaurus may have also been the first dinosaur to take to the water, swimming in North Africa's rivers some 97 million years ago, researchers reported on Thursday.
Floating like a crocodile to stalk prey, the 50-foot-long (15.2 meters) predator bore a massive sail on its back that would have risen from the water like a shark's fin. The carnivore probably ate fish, ancient crocodiles, and anything else afloat."It was the biggest carnivorous dinosaur, but Spinosaurus wasn't a land animal, " says University of Chicago paleontologist Nizar Ibrahim, a National Geographic Society Emerging Explorer who led the discovery of the new fossils. "This was a creature adapted to life in the water."Up to then, dinosaurs had ruled only the land. After 150 million years of dinosaur evolution, "suddenly we see these adaptations in Spinosaurus where it is able to swim, " says University of Chicago paleontologist Paul Sereno, a co-author of Thursday's report in the journal Science describing new fossils that reveal how the fearsome ancient predator lived. (Read "Mr. Big" in National Geographic magazine.)The fossil bones of Spinosaurus aegyptiacus described in the study turned up in sandstone beds in the Moroccan Sahara. Complete with skull, claws, and bones that formed the sail on its back, the fossils reveal a crocodilian snout, paddle-like feet, and dense bones that aided buoyancy, adding up to a life aquatic for the giant predator."
