Hadrosaurus

bulky lizard

• hadros · Greek · bulky, stout, thick
• sauros · Greek · lizard

The name combines the Greek "hadros" (bulky or stout) with "sauros" (lizard), referring to the animal's large, robust build. It was named by Joseph Leidy in 1858 for a partial skeleton found in Haddonfield, New Jersey. It was one of the first dinosaur skeletons found in North America that was reasonably complete, and it gave its name to the hadrosaurs, or duck-billed dinosaurs.
