An Allosaurus fossil on display in Guyot Hall, home to the Geosciences Department of Princeton University. Excavated at the Cleveland Lloyd Dinosaur Quarry in 1941 by a team led by Professor Glenn Jepson. The skeleton, which is 25 feet long and 12 high, is real bone except for the skull. It is a remnant of the natural history museum housed on the first floor of Guyot from 1910-2002, and was not removed because the cost was too great.
