UO 5141 Lili's Site (Miocene of the United States)

Where: Crook County, Oregon (44.0° N, 120.0° W: paleocoordinates 43.9° N, 114.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Mascall Formation, Hemingfordian (20.4 - 16.0 Ma)

• late Hemingfordian; unconformably capped by the 7.02 Ma Rattlesnake Ashflow Tuff

Environment/lithology: terrestrial; lithology not reported

• Mascall Formation sediments are composed of primarily fluvial and lacustrine deposits, generally of a uniform tan to light yellow color. In the Crooked River Basin, the Mascall has significantly more fluvial sequences than even the lowermost portion of the type area (Bestland, 1998), with thick cross-bedded sandstones and pebble conglomerates common

Size class: macrofossils

Collection methods: surface (float)
