Summary:

[Pg. 6, 7], correlation chart, structure sections A, B, and C. Antelope shale. Shown on correlation chart (of Rumsey Hills-Capay Valley-Wilbur Springs area) and on structure sections in Colusa County, California. Beds vertical to overturned. Thickness 4,200 to 5,200 feet. Underlies Venado sandstone; overlies Salt Creek conglomerate (new). Age is Late Cretaceous (Delevanian).
[Origin of name not stated. Type locality not designated.] Occurs in Rumsey Hills-Capay Valley-Wilbur Springs area on west side of Sacramento Valley, north-central CA.

Summary:

Pg. 40-47. Description of Upper Cretaceous pelagic Foraminifera from "Antelope shale" of Taliaferro (1954). Considered a provisional name. Kirby (1943, California Div. Mines Bull., no. 118) referred to these strata as Horsetown formation of Shasta group. J. Lawton (Stanford unpub. thesis) has proposed term Fiske Creek formation for "Antelope shale" which is junior homonym of Antelope formation (Miocene) of Kern County, described by Noble (1940, AAPG Bull., v. 27, no. 3). Age is early Late Cretaceous (Cenomanian), based on foraminifers. Comparisons made with fauna of type Calera limestone, Rockaway Beach, San Mateo County, California.

Summary:

Pg. 2287. If it is desirable that Shasta series be restricted to Early Cretaceous, base of conglomerate below so-called Antelope shale of Taliaferro appears to good choice for its upper limit and is so considered in this report.

Summary:

QUINQUECAPSULANIA SPINOSA Pessagno n.sp. has been found in five localities in "Antelope Shale"/"Fiske Creek Formation" in strata ranging in age from early to late Cenomanian (dating based on associated planktonic Foraminifera and Mollusca).
