BIG AL TWO is one of the most complete Allosaurus skeletons ever collected, and was discovered in 1996 by a field crew led by Kirby (Hans Jakob) Siber, of Siber & Siber, Ltd. (Aathal-Seegraben, Switzerland). BIG AL TWO was collected from the famous Howe Ranch near Shell, Wyoming, and was prepared and mounted by Ben Pabst and crew from Siber & Siber, Ltd. Black Hills Institute staff sculpted the missing bones and created molds to make cast replica skeletons.

Available as an unpainted, unmounted cast suitable for some research or reference purposes. Note: some portions of the original fossil may have been scientifically restored.
