Noun: * A taxonomic genus of extinct, large, quadrupedal, armored herbivorous dinosaurs from the Jurassic and Cretaceous periods. The name is primarily used in scientific classification. The most famous species within this genus is Stegosaurus stenops, known for its distinctive double row of large, upright bony plates along its back and spikes on its tail.
