Sure, Spinosaurus might have lived near water and hunted in it. But, they argued, there wasn't enough evidence to show it could swim or chase prey underwater. Instead, they proposed this dinosaur was more like a heron than a crocodile. Herons wade in the water and fish from the shore or by wading in shallows.. For years, controversy has swirled around how a Cretaceous-era, sail-backed dinosaur—the giant Spinosaurus aegyptiacus—hunted its prey. Spinosaurus was among the largest predators ever to prowl the Earth and one of the most adapted to water, but was it an aquatic denizen of the seas, diving deep.

Back in the Cretaceous period, 145 to 66 million years ago, dinosaurs dominated the land and sky. They also, a new paper argues, terrorized the aquatic realm. Recent fossil evidence has revealed that Spinosaurus aegyptiacus, among the largest of all known carnivorous dinosaurs, was a creature of the water, with a center of gravity and a giant tail fin perfect for swimming.
