Stratigraphy
| Formation: | Capay | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: The invertebrate faunas from these localities have been assigned to the Capay stage of the Californian marine Eocene by Merriam and Turner (1937) and are correlative with one another and with faunas from the Cerros shale member of the Lodo formation, north of Coalinga, and from glauconitic shales and sandstones at Marysville Buttes. | |||||
Lithology and environment
| Primary lithology: | sandstone |
| Secondary lithology: | conglomerate |
| Lithology description: gritty sandstones and conglomerates in Smith Canyon | |
| Environment: | deep subtidal indet. |
| Geology comments: in striking contrast to the Winters locality,here the number of molluscs is more than 15 times as great as the number of corals
the presence of Madracis suggests a habitat in tropical or subtropical waters, with a depth somewhat greater than 74 meters, but probably not exceeding 366 meters, the max. range of Balanophyllia. Apparently the Smith Canyon fauna lived at considerably shallower depths than the Winters fauna but under similar thermal conditions. | |
