Revueltosaurus Quarry (PFV 297) (Triassic of the United States)

Where: Arizona (35.1° N, 109.8° W: paleocoordinates 10.7° N, 48.3° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Petrified Forest Member (Chinle Formation), Norian (228.0 - 208.5 Ma)

• middle part of member (equals Painted Desert Member of Lucas 1993), approx. 25 m below Black Forest Bed. Multiple lines of evidence indicate a Norian (Revueltian) age, including a radiometrically dated tuff (dated at 209Ma), the Black Forest Bed, which lies 25 m above the quarry.

• bed-level stratigraphic resolution

Environment/lithology: "floodplain"; paleosol/pedogenic, blue mudstone

• "proximal floodplain deposits associated with a levee deposit just lateral to one of the prominent local sandstones common in the region."
• "a moderatley pedogenically modified mudstone"

Size class: macrofossils
