I WONDER - Who Discovered The Stegosaurus?

In 1877, O'Neal Marsh discovered both the Apatosaurus and Segnosaurus dinosaurs. He named the Stegosaurus, meaning 'roofed lizard', due to its bony plates resembling roof tiles. The first Stegosaurus fossil was found in Colorado, leading to its designation as the state dinosaur. Fossils have been found in western North America and Portugal.
