Pancake Range (PROXY) (Cretaceous of the United States)

Where: Nye County, Nevada (38.8° N, 115.8° W: paleocoordinates 40.4° N, 67.0° W)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Newark Canyon Formation, Aptian (125.0 - 113.0 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: lacustrine; massive, fine-grained, brown mudstone

• "We interpret the first lithofacies to be both hyperconcentrated-flow- and lacustrine deposits."
• "The first lithofacies is a massive, dark-brown mudrock. There are no pedogenic features or sedimentary structures. These beds can be tens of meters thick. Bones as well as other non-bioclasts are found “floating” in the fine-grained matrix."

Size class: mesofossils
