These huge creatures lived in the sea the same time dinosaurs roamed the Earth. Find out how big they were, what they ate - facts, pictures and information for kids. Of all the dinosaurs, it was Spinosaurus that took to the water. This was the biggest meat eating dinosaur that we know of. Scientists think it could live on both land and water like crocodiles. But it could definitely swim (it had webbed feet) and hunt in the water. It probably ate sharks and large fish. Spinosaurus is the only dinosaur we know that spent time living in the water.
