1. Sediments and Fossils Marker
Captions: (upper right) Pliocene fossils buried in the Hagerman Fossil Beds sediments, such as this horse skull, are some of the most diverse and plentiful in the world.l (bottom left) Sediment layers range from a few inches to several feet, depending on the extent of ancient river and lake deposition.; (bottom right) Skulls and other bones of the Hagerman Horse were preserved when they were buried under the sediments.
Inscription.  The rock layers in the bluff across the river are made of sediments - particles of sand, silt, and clay. These layers, called strata, were carried here by the ancient Snake River and were deposited as the river entered an ancient lake. This process usually occurred slowly, taking many years to build up just a few inches. During floods, however, strata could form rapidly, often trapping plants and animals within the sediments.
Fossils - traces or remnants of organisms from the geologic past - are buried in the layers. Bones become fossils when their organic cells are slowly filled or replaced with minerals. Fossils found here include mammals, birds, fish, reptiles, amphibians and plants that scientists have dated from three to four million years old.
