Allosaurus

Part of Hall of Saurischian Dinosaurs.

An exhibition of an Allosaurus fossil skeleton mounted dramatically over the partial spine skeleton of its prey. Allosaurus (Hall of Saurischian Dinosaurs)

Allosaurus is shown feeding on a carcass with bones marked by grooves, possibly from the teeth or claws of the 140-million-year-old predator. Allosaurus teeth found nearby inspired the idea for the mount.

The Allosaurus co-stars in one of the Museum's most popular exhibits: the Barosaurus mount in the Theodore Roosevelt Rotunda. In the world's tallest freestanding dinosaur mount, the Barosaurus is rearing up to defend its young against an Allosaurus.
