Abstract
This paper describes the critical Eocene section at Canada de Santa Anita, Santa Barbara County, California. The formation of early workers is subdivided into the Anita shale (new name), Matilija sandstone, Cozy Dell shale, Sacate formation (new name), and Gaviota formation in ascending stratigraphic order. Detailed study was confined to the Eocene strata below the type Gaviota formation. The general east-west trending anticlinal structure is complicated by strike faulting. Foraminifers in the Anita shale, which is disconformable on Cretaceous beds, suggest a middle Eocene age for the formation. The molluscan faunule in the Matilija is believed to belong in Clark and Vokes' (1936) Transition stage below the Tejon and above the Domengine. Of particular sign ficance are faunules from the Cozy Dell; these belong in Laiming's (1940) Zones A-1 and A-2. The upper member of the Sacate formation contains a Turritella related to T. variata, the abundant Gaviota species.
