Fusulinids from the middle part of the metasedimentary 'Garlock Series' in the El Paso Mountains, California, include Schwagerina? hollandensis n. sp., Schwagerina garlockensis n. sp., S. randensis n. sp., and five unnamed species of Schwagerina. No closely similar fusulinid faunas are known from North America, but the stage of evolution of these fusulinids suggests a very late Wolfcampian or very early Leonardian age. This El Paso Mountain fauna has some species, such as S. randensis, which appear related to Asian and eastern European species of late Asselian or early Sakmarian age.
