Allosaurus fragilis, juvenile left femur thigh bone
Late Jurassic, western North America

Allosaurus fragilis was one of the largest predatory dinosaurs of the Late Jurassic.  However, even this great carnivorous dinosaur had to start small.  Here is a replica of an Allosaurus thigh bone froma juvenile dinosaur that measures only 10 inches in length.  A large adult Allosaurus can have a femur nearly four feet in length!  The rounded upper end is where the femur attached to the hip socket and the large boney projections are for the attachment of muscles coming from the hip.

This fossil cast comes with an informative card.
