Where: Nevada (37.5° N, 115.7° W: paleocoordinates 2.5° S, 95.5° W)
• coordinate estimated from map

• member-level stratigraphic resolution
Environment/lithology: paralic; green shale and brown siltstone
•with brown and maroon siltstone and shale with minor
•amounts of quartzite and limestone.
Size classes: macrofossils, mesofossils, microfossils
