Styracosaurus, currently grouped into the Edmontosaurus, a species of flat-headed or saurolophine hadrosaurid ornithopod dinosaur, or "duck-billed dinosaur", lived at the end of the Cretaceous Period, during the Maastrichtian stage, around 70 million years ago, representing the last three million years before the extinction of dinosaurs. In addition to their ducklike beaks and webbed front feet, some of the fossil "mummy" duck-billed dinosaurs had powerful jaws with hundreds of blunt teeth that were ideal for grinding fibrous land plants.
The Hall of Ornithischian Dinosaurs, one of two halls in the David H. Koch Dinosaur Wing, displays fossils from Ornithischians—dinosaurs characterized by a backward-pointing extension of the pubis bone, which is thought to have helped to support the enormous stomachs that these dinosaurs needed to digest the masses of tough vegetation they ate. Exhibits within this hall explore genasaurs, which are defined by the development of inset tooth rows that form cheeks, and the cerapods, identified by an uneven covering of tooth enamel.
The American Museum of Natural History (AMNH), located at Central Park West and 79th Street, comprises of 28 interconnected buildings housing 45 permanent exhibition halls, in addition to a planetarium and a library, across 2-million square feet. The collections contain over 33 million specimens of plants, animals, fossils, minerals, rocks, meteorites, human remains, and human cultural artifacts. Founded in 1869, the museum opened in the original Victorian Gothic building designed by J. Wrey Mould in 1877. A southern expansion, a rusticated Richardsonian Romanesque by J. Cleveland Cady, extends 700 feet along West 77th Street and in 1936, John Russell Pope added the overscaled Beaux Arts entrance on Central Park West.
