lower pat of subchron C32n
Also assigned to Sedano Fm. or its equivalent
Lithology and environment
Primary lithology:"cross stratification",hardground conglomeratic sandstone
Secondary lithology:black siltstone
Includes fossils?Y
Includes fossils?Y
Lithology description: Multidirectional cross-laminated sands with microconglomerates in the bottom-sets, rarely more than 1m thick. Strata become massive toward the top, and are frequently intersected by abrasion surfaces showing an iron-mineralized crust or hard-ground. The most important bone accumulation is between two of these hardgrounds. The unit is topped by two black silt beds.
Environment:coastal indet.
Glacial or sequence phase:regressive
Geology comments: upper foreshore and backshore environments to a subcontinental, plant-rich perhaps swampy environment. The vertebrate bearing levels indicate a continental depositional environment affected by high-energy episodes, a fluviatile environment.
