The Life and Times of Big Al

The Late Jurassic dinosaur Allosaurus has been known for over 100 years. However, it was not until 1991 when Big Al, a young, 95 percent complete Allosaurus fragilis skeleton with numerous injured bones was discovered, that one of the most fascinating paleontological mysteries began to unfold. The skeleton was found on public lands administered by the Bureau of Land Management near Shell, Wyoming, in the Upper Jurassic Morrison Formation. Research on this specimen has provided exciting new information on Allosaurus (the dominant predator of the Late Jurassic of North America), as well as the environment in which he lived. Big Al has gained international recognition as the story of his tragically painful life, early death, and rapid burial has been told through interactive exhibits and state-of-the-art television programs at the University of Wyoming Geological Museum.
