Stegosaurus stenops

† Stegosaurus stenops is the best-known species of Stegosaurus from the Late Jurassic Morrison Formation, bearing broad upright plates and four thagomizer spikes. Nearly complete skeletons allow detailed reconstruction of its unusual body plan.

Diet & Feeding

Herbivore

Stegosaurus stenops 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 stenops 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.
