Rap Hill (PFV 216) (Triassic of the United States)

Also known as RAP Hill

Where: Arizona (34.8° N, 109.8° W: paleocoordinates 10.5° N, 48.4° W)

• coordinate based on nearby landmark

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

• Also referred to as Painted Desert Member of the Petrified Forest Formation

Environment/lithology: fine channel fill; gray, green, red claystone

• "The Jeremiah’s Perch and RAP Hill sites are developed in two hydromorphic pedofacies that represent zones of groundwater saturation and fluctuation, respectively, associated with floodplain environments. The fossiliferous layers fill localized depressions in the top of a thick succession of fine-grained facies interpreted as of near-channel origin and likely represent shallow floodplain ponds, perhaps associated with abandoned channels"
• "The fossiliferous layers are laminated light greenish gray (5GY 7/1) claystone, grading upward into variegated light greenish gray, gray (N/5 to N/6), and red (10R 5/1 to 10R 5/2) claystone. These colors are typically produced as reduced iron and manganese are removed during prolonged saturation of sediment."
