Pierre Shale is a dig site in Jurassic World Evolution. It was added with the Return to Jurassic Park DLC.

InGen Database Description

The Pierre Shale Group is found in eastern South Dakota and western Wyoming in the United States of America. During the Cretaceous period, this area would have been part of the Western Interior Seaway, a marine environment.

The Pierre is formed out of shale, sandstone, and bentonite. This group has been host to multiple fossil finds, including Pteranodon specimens, and the Cretaceous sea turtle Archelon.
