Anatotitan is a lesser-known member of the duck-billed dinosaur family that lived in last part of the age of dinosaurs. It was a typical member of this plant-eating family, with a large, broad duck-shaped bill that contained hundreds of teeth.

The type specimen was discovered in 1876 and named after famed collector Edward Drinker  Cope, who organized many dinosaur-hunting expeditions in the late 19th century. One other member of the genus is known - A. longiceps, and both are mounted in the American Museum of Natural History. Like other hadrosaurs, Anatotitan was most likely a herd-dwelling animal.
