Like pages in a book, the layers of sedimentary rock that are exposed on the Colorado Plateau tell us much about the diversity of environments that have come and gone over a period of hundreds of millions of years. This region is recognized as one of the finest earth-science laboratories in the world. Analysis of the fossil record and new discoveries across the plateau are answering questions, solving mysteries, and making connections that help us understand the history of life worldwide. "Life In Stone" tells the story of past environments and current discoveries with numerous illustrations and lively text written for a general audience.
