Stegosaurus sulcatus

† Stegosaurus sulcatus is a Late Jurassic stegosaurid species from the Morrison Formation, diagnosed by features of its plates and vertebrae. Like other Stegosaurus species, it was a large herbivore with a tiny brain relative to body size.

Diet & Feeding

Herbivore

Stegosaurus sulcatus was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Jurassic Late Mesozoic Era

Stegosaurus sulcatus lived during the Jurassic Late period of the Mesozoic Era, approximately 161,5 to 145,0 million years ago.

One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
