Rawley Springs (Devonian of the United States)

Where: Rockingham County, Virginia (38.5° N, 79.1° W: paleocoordinates 35.3° S, 28.5° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Hampshire Formation, Late/Upper Devonian (382.7 - 358.9 Ma)

• bed-level stratigraphic resolution

Environment/lithology: alluvial fan; lithified sandstone and lithified, bioturbated mudstone

• coal bed up to 1.5 m thick rests on a bioturbated and partly rooted mudrock with uneven topography at the top of a fluvial fining upward cycle. Coal is in turn cut by high relief erosion surface of the next cycle above. Within both cycles the erosion surface is overlain by trough cross-stratified hematite cemented sandstones which fine upward into bioturbated and oxidized siltstone and mudstone. Section indicates that plant axes are from base of the sandstone layer.

Size class: macrofossils

Collection methods: surface (in situ),
