Students from a Community College and a university, along with their respective professors, assemble at the fossil trench at Lygodium Gulch, a classic fossil leaf-bearing locality in the Ione Basin, western foothills of the Sierra Nevada, Amador County, California. They had volunteered to help paleobotanist Howard Schorn, retired Collections Manager Of Fossil Plants at the University California Museum Of Paleontology in Berkeley, collect fossil plants from the Middle Eocene Ione Formation. The suites of paleobotanical specimens recovered here would be used in a project, underwritten by the National Science Foundation, to study the many Eocene fossil floras of the Sierra Nevada region, to try to determine the ancestral paleoelevations and paleoclimate of the Eocene Sierra Nevada.

Please note: All fossil localities in the Ione Formation of Amador County, California, presently occur on private property; explicit permission from the land owners must be secured before collecting fossils there.
