If you think sharks are terrors in the water, wait until you hear about the Spinosaurus.

Fossils from Morocco have provided the most complete skeleton of the aquatic dinosaur, which roamed the waterways during the Cretaceous period, according to research published in the journal Science.

The most complete skeleton of the Spinosaurus was discovered by a research team in Morocco recently, according to the journal.

The 50-foot-long carnivorous predator was larger than the T-Rex and had adaptations that allowed it to swim in water and roam on land, according to researchers.

Among those evolutionary features were feet like pedals, a nostril on the far back of the head and hippo-like bone density.
