Promontory Butte Flora (Carboniferous to of the United States)

Where: Arizona (34.0° N, 111.0° W: paleocoordinates 0.3° N, 41.6° W)

When: Carboniferous to Carboniferous (358.9 - 298.9 Ma)

• Correlates with the lower part of the Abo Formation of central New Mexico.

• bed-level stratigraphic resolution

Environment/lithology: argillaceous shale

• The Coconino Sandstone of teh mid-Permian age is visible at the top of Promnotory Butte and forms white to yellow massive cliffs exhibiting wedges of cross-bedding. This SS grades downward into a continous redbed sequence of siltstone-sandstone, then a limestone interbed, a cross-bedded red siltstone, a calcareous shale that weathers to pebble-sixed fragments with a limonite stain, with the plant horizon 1-3 m thick over a coaly layer.

Size classes: macrofossils, microfossils

Preservation: adpression

Collection methods: surface (in situ),
