stegosaurus, complete 3D skeleton.

The stegosaurus, a famous Upper Jurassic dinosaur, fascinates with its unique anatomy. Its back was adorned with bony plates, perhaps acting as sun sensors or visual signals. At the tip of its tail, thagomizers, formidable defensive spikes, ensured its protection. Its small but effective head housed teeth adapted to its herbivorous diet. Despite a modest brain, its senses gave it an acute perception of its environment, essential for escaping predators. Its extinction at the end of the Cretaceous remains an enigma of prehistory.

Bone plates: Stegosaurus bone plates were probably used for thermoregulation, acting as solar panels to absorb the sun's heat or as a means of visual communication with other stegosaurids.

Defensive tail: At the end of its tail were four bony spikes, called "thagomizers". These spikes were probably used as a means of defense against predators or during intra-specific fights.

Diet: Like most herbivorous dinosaurs, Stegosaurus fed mainly on plants, such as ferns, cycads and conifers. Its teeth were adapted to crush fibrous plant matter.

Size and weight: Stegosaurus was around 9 meters long and could weigh up to 5 tons, making it a medium-sized dinosaur compared with some other contemporary dinosaurs.

Habitat: Stegosaurus is thought to have lived in what is now North America and Europe, where it evolved in forested and semi-arid environments.

Extinction: Like most dinosaurs, the stegosaurus became extinct at the end of the Cretaceous period, around 66 million years ago. The exact reasons for its extinction are not fully understood, but theories suggest the influence of climate change, natural disasters and competing evolutionary pressures.
