|Spinosaurus, the Biggest Meat-Eating Dino Ever Discovered, Ate Entire Sharks|
"Every time I see the sail on Spinosaurus, I'm going to hear the Jaws theme in my head," says lead study author Nizar Ibrahim, a vertebrate paleontologist at the University of Chicago.
The first fossils of Spinosaurus aegyptiacus were discovered more than a century ago by German paleontologist Ernst Stromer von Reichenbach in the Egyptian Sahara. But all of Stromer's fossils were destroyed in World War II during the 1944 Allied bombing of Munich, leaving much uncertain about this carnivore. In 2008, however, 97-million-year-old fossils appeared across the Sahara, in Morocco. Those fossils are now, at long last, revealing Spinosaurus.
The fossils suggest an adult Spinosaurus would be more than 49 feet long head to tail, more than 9 feet longer than the largest known Tyrannosaurus rex. "It was the largest predatory dinosaur to roam the Earth that we know of," Ibrahim says.
