Spinosauridae (meaning 'spined lizards') is a family of carnivorous theropod dinosaurs from the Jurassic and Cretaceous periods. They are unique among other meat-eating dinosaurs from their more water-based lifestyle, which involved a diet of mostly fish. Spinosaurid fossils have been found all over the world, including Asia, South America, Europe, Africa, and Australia.
