Also known as PEFO
Where: Apache County, Arizona (35.1° N, 109.8° W: paleocoordinates 10.8° 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)
• "Approximately 54 meters below a prominent tuffaceous sandstone bed known as the Black Forest Bed (Ash 1992). Riggs et al. (2003) have determined a maximum age for this bed, and thus a minimum age for the quarries, of 213 +/- 1.7 based on U-Pb ages of detrital zircons."
• bed-level stratigraphic resolution
Environment/lithology: fine channel fill; gray, green claystone and gray, red, silty claystone
Size class: macrofossils
Collection methods: quarrying, surface (float), surface (in situ), mechanical,
