Fossil Treasures of the Anza-Borrego Desert - The Last Seven Million Years

Southern California's Anza-Borrego Desert State park is a vast, mostly arid desert, but the ancient landscapes of Anza-Borrego were richly populated riparian forests and savanna, and before that, there was a tropical inland sea teeming with marine life. The Park's eroded badlands provide North America's most continuous history of life for most of the last seven million years - one of the richest fossil records of its time in the western hemisphere - opening windows onto the region's long vanished past.
