About 99 million years ago, Spinosaurus (Spinosaurus aegyptiacus) was common in North Africa. Evidence (with the nostrils on top of their snouts and webbed feet) shows that it was terrestrial and semiaquatic, feeding mainly on fish. This dinosaur was first bipedal but later grew to be quadrupedal. It was the largest, longest, and heaviest among carnivorous dinosaurs with a long, low, narrow skull, large, robust forelimbs, and a long tail with neural spines thought to be for intimidating other animals or thermal regulation. It also had crocodile-like teeth and dense bones like those of the manatees.
The Spinosaurus had an overall length between 46’-59’ (14-18 m), overall standing height of 20’-25.6’ (6.1-7.8 m), body width of 5.25’-6.9’ (1.6-2.1 m), and weight from 14,100-16,300 lb (6,400-7,400 kg). The typical lifespan of the Spinosaurus was between 25-30 years.
