rmored stegosaurid dinosaur. They lived during the Late Jurassic period 150 million years ago in what is now western North America. In 2006, a specimen of Stegosaurus was announced from Portugal, showing that they were present in Europe as well. Due to its distinctive tail spikes and plates, Stegosaurus is one of the most recognizable dinosaurs. Stegosaurus grew up to 10 meters (33 ft) in length. Some form of armor appears to have been necessary, as Stegosaurus species coexisted with large predatory theropod dinosaurs, such as Allosaurus and Ceratosaurus. '
In the late Jurassic segment, Stegosaurus is first seen digging for water like a modern elephant but fails. Later, a male Stegosaurus meets a female and tries to show off. Then a Ceratosaurus comes out of nowhere but the male's tail spikes hurts the predator. He tries to mate with the female but she rejects him. Eventually, the female decides that he is a healthy individual and the two mate.
