Geography

Country:	United States	State/province:	California	County:	Fresno
Coordinates:	36.4° North, 120.4° West (view map)
Paleocoordinates:	43.9° North, 93.2° West (Wright 2013)
Basis of coordinate:	estimated from map
Geographic resolution:	outcrop

Time

Period:	Paleogene	Epoch:	Eocene
Stage:	Ypresian	10 m.y. bin:	Cenozoic 2
Key time interval:	Ypresian
Age range of interval:	56 - 48.07 m.y. ago

Stratigraphy

Formation:	Lodo	Member:	Cerros Shale
Stratigraphic resolution:	group of beds
Stratigraphy comments: Assigned to the "Arroyo Hondo" formation (lower part of the "Capay Stage") by Vokes (1939) and Miller & Downs (1950), but the Lodo Formation is now used for this unit. Calcareous nannofossils indicate the CP10 (Tribrachiatus orthostylus) zone of early Eocene age and the transition between the CP10-CP11 (Discoaster lodoensis) zones, according to Squires (1988).

Lithology and environment

Primary lithology:	lithified "shale"
Environment:	deep-water indet.
Geology comments: Foraminifera indicate bathyal depths for the lower part of the Lodo (Stinemeyer, 1974).

Taphonomy

Modes of preservation:	body
Size of fossils:	macrofossils

Collection methods and comments

Collection methods:	survey of museum collection
Reason for describing collection:	taxonomic analysis
Museum repositories:	UCMP
