The stegosaurus often inhabits grasslands, where nutritious vegetation is plentiful and only its dorsal plates rise above waving fields of tall grass. The stegosaurus is among the most curious of dinosaurs, and hunters often find it easy to bait them with shiny trinkets or strange noises. A stegosaurus is about 30 feet long, 16 feet high at the top of its highest dorsal plate, and weighs between 2 and 3 tons.
