An artist rendition of the ecosystem when Hagerman Fossil Beds were deposited during the Pliocene Epoch. A fluvial (river) and floodplain environment around the edge of ancient Lake Idaho deposited layers of sand, silt and clay at least 600 feet thick. Layers of sediments have preserved an exquisite world class assemblage of Pliocene fossils. The Smithsonian Institution directed fossil excavations in the early 1930's and many other museums and research institutions have conducted research here ever since.
