Fagopsis longifolia: an Extinct Species from Florissant
Fagopsis longifolia is one of the more common fossil plants found in the Florissant Formation. Located 35 miles west of Colorado Springs, Florissant Fossil Beds National Monument has one of the most diverse fossil deposits in the world—more than 1,700 different species have been described from this ancient lake deposit. Fagopsis, a genus that became extinct at the end of the Eocene, is thought to have been a member of the beech family (Fagaceae). Originally identified as the water elm, Planera, these fossil leaves were assigned to the genus Fagopsis.
