MNA locality 1645, Kachina Village (Permian of the United States)

Where: Arizona (35.1° N, 111.7° W: paleocoordinates 9.6° N, 36.2° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Fossil Mountain Member (Kaibab Formation), Kungurian (279.3 - 272.3 Ma)

• Lower Fossil Mountain Member

• group of beds-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified limestone

• Characterised by a distinctive chert nodule unit occurring within relatively unconsolidated orange-brown sands and capped by red-orange limestone.

Size class: microfossils

Collection methods: chemical, mechanical, sieve

• The materials for this study were mostly collected from the loosely consolidated sandy limestones, processed in a weak acetic acid solution and screen-washed through graded screens. Sediment residues were then picked under a binocular microscope. Larger specimens from large limestone blocks were prepared mechanically. Repository: Museum of Northern Arizona (MNA).
