Spinosaurus News 2024. Spinosaurus, the longest predatory dinosaur known, is opening its elongate jaws, studded with conical teeth, to catch a sawskate. Scans of the spinosaur dinosaurs ceratosuchops and baryonyx have revealed that the brains of these dinosaurs were more similar to their relatives than first realised.
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 to chase. Spinosaurus, the largest predatory dinosaur that sported a massive sail on its back, would have made for a very slow and awkward swimmer, according to new research.
