Buckskin Wash (Cretaceous to of the United States)

Where: Emery County, Utah (38.6° N, 110.7° W: paleocoordinates 36.7° N, 60.0° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Buckhorn Conglomerate Member (Cedar Mountain Formation), Berriasian to Berriasian (145.0 - 132.9 Ma)

• "A thick carbonate paleosol locally overlies the Buckhorn and a similar paleosol has been used to define the base of the Cretaceous elsewhere....Well-developed paleosols may occur at a number of stratigraphic positions within the Cedar Mountain Formation...the recent discovery of a possible ankylosaur...suggests a Cretaceous age."

•middle part of member

• bed-level stratigraphic resolution

Environment/lithology: fluvial; paleosol/pedogenic conglomerate and chert

• "a northeast-flowing river system along the west flank of the San Rafael Swell"
• "the Buckhorn consists largely of a chert-pebble to cobble conglomerate up to 25 m thick"

Size class: macrofossils

• possible ankylosaur skeleton

Preservation: mold/impression

Collection methods: surface (in situ),
