The Tulare Formation (/tʊˈlɛəri/ ^ⓘ) is a Pliocene to Holocene epoch geologic formation in the central and southern San Joaquin Valley of central California.^[1]^[2]

Geology

It overlies the San Joaquin Formation, and can be up to 4,000 feet (1,200 m) thick.^[1]^[2]

Its sediments consist mainly of unconsolidated deposits of clay, silt, sand, and gravel.^[1]

Fossils

Many freshwater fossils are preserved in the formation, dating back to the Neogene and Quaternary Periods of the Cenozoic Era.^[3] They include the largest fossil assemblage of clams and snails known on the Pacific Coast.^[1]
