During the Permian geologic period, which spanned 47 million years, 90% of the planet’s species were lost in the largest mass extinction in Earth’s history. The cause may have been an enormous asteroid, massive volcanic eruptions or the release of methane reservoirs in the ocean. Whatever event contributed to the world evolving from icehouse to greenhouse, most of the planet’s marine life, animals and plants were unable to adapt and sediments from the period contain their fossils.
For this book, plant fragments were pigment printed on pages taken from a found Geological Survey of the Permian Basin by the United States Department of the Interior. This small volume commemorates the loss of species. Two signatures. Cover of book cloth over board and watch parts embedded in polymer clay onlay. Paper wrapper. 48 pages, 6.5” x 5.25” x .5”.
