Abstract:
Vaqueros fossils, including Ostrea vaquerosensis and Pecten magnolia, have recently been found at several localities in a sandstone member occurring in the upper part of the Santos shale. This sandstone member, here referred to as the "Agua sandstone," is traceable from the vicinity of Carneros Creek to the mouth of Cedar Canyon, several miles farther northwest, and, in places, reaches a thickness of more than 300 feet.
Although evidence from other regions had previously suggested it, this discovery proves the Vaqueros age of at least the lower two-thirds of the Santos shale and necessitates its removal from the Temblor. As a result, the present known extent of the Vaqueros sea in the San Joaquin Valley has been considerably increased.
