Stegosaurus duplex

† Stegosaurus duplex is a Late Jurassic stegosaurid from the Morrison Formation of Colorado, one of several Stegosaurus species described during the Bone Wars. It is currently considered a junior synonym or valid species pending morphological review.

Diet & Feeding

Herbivore

Stegosaurus duplex 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 duplex 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.
