The Howe Quarry, also known as the Howe Dinosaur Quarry, is a fossil site located on private property in Shell, Wyoming. The site is best known for its well preserved Jurassic dinosaur bone beds. The Allosaurus specimen "Big Al", which was featured in the BBC Walking with Dinosaurs special The Ballad of Big Al, was discovered at the fossil site.
Fossils were first uncovered from this locality in the early 1930's by then Curator of Vertebrate Paleontology Barnum Brown, a fossil hunter employed by the AMNH. The quarry was closed for nearly sixty years. When the quarry was re-opened, Big Al and Big Al Two were both uncovered, with the latter representing the most complete skeleton to date of this species .
