Stage:Turonian 10 m.y. bin:Cretaceous 6
Key time interval:Turonian
Age range of interval:93.90000 - 89.80000 m.y. ago
Stratigraphy
Formation:Ladd Member:Baker Canyon
Lithology and environment
Primary lithology: sandstone
Lithology description: "fossiliferous sandstone overlaying the gray basal conglomerate"
Environment:shallow subtidal indet.
Geology comments: "The strata...were deposited along a shoreline in warm, very shallow sublittoral water (Saul, 1982). The sedimentological details of the Baker Canyon Member indicate a fluctuating, moderate to high-energy, lower to upper shoreface paleoenvironment associated with a fan-delta setting (Cooper et al.1982)"
