Stegosaurus in popular culture
The 19th century American paleontologist Othniel Charles Marsh had named and first described Stegosaurus in 1877, originally interpreted from incomplete fossil remains as an aquatic reptile with turtle-like armor plates that lay flat on its back. Later discoveries allowed Marsh to restore Stegosaurus more accurately as a terrestrial plant-eating dinosaur, initially restored with a single row of plates aligned vertically along its back with eight pairs of spikes on the end of its tail.
