Stegotaur is likely derived from the Stegosaurus, a genus of stegosaurid armoured dinosaur from the Late Jurassic period (late Kimmeridgian to Early Tithonian) in what is now western North America. Due to its distinctive tail spikes and plates, Stegosaurus is one of the most recognizable dinosaurs, along with Tyrannosaurus, Triceratops, and Apatosaurus. The name Stegosaurus means "roof-lizard" and is derived from the Greek στέγος-, stegos- ("roof") and σαῦρος, -sauros ("lizard").
