Scientists report first semiaquatic dinosaur, Spinosaurus: Massive predator was more than 9 feet longer than largest T. rex

11 septiembre 2014

Scientists today unveiled what appears to be the first truly semiaquatic dinosaur, Spinosaurus aegyptiacus. New fossils of the massive Cretaceous-era predator reveal it adapted to life in the water some 95 million years ago, providing the most compelling evidence to date of a dinosaur able to live and hunt in an aquatic environment. The fossils also indicate that Spinosaurus was the largest known predatory dinosaur to roam the Earth, measuring more than nine feet longer than the world’s largest Tyrannosaurus rex specimen.
