Stegosauria

† Stegosauria is the clade of plated ornithischian dinosaurs, with fossil material documented from Cretaceous deposits of Niger. Stegosaurs dominated medium to large herbivore niches in Jurassic ecosystems worldwide before declining in the Cretaceous.

Diet & Feeding

Herbivore

Stegosauria 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

Cretaceous Early Mesozoic Era

Stegosauria lived during the Cretaceous Early period of the Mesozoic Era, approximately 145,0 to 100,5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
