Where: Inyo County, California (36.3° N, 117.0° W: paleocoordinates 27.8° S, 58.5° W)

• coordinate estimated from map

When: Lippincott Member (Lost Burro Formation), Late/Upper Emsian (402.5 - 391.9 Ma)

• The vertebrate-bearing unit was regarded as forming part of the lower part of the Lippincott Member of the Lost Burro Formation by Snow (1990), a correlation also supported by this study... The lithologic and stratigraphic differences between the two units suggest that the vertebrate-bearing unit is a variant of the lower part of the Lippincott Member.

•Elliott 2016: "A late Emsian age (inversus-serotinus Zones) is suggested for this unit based on conodont data and lithostratigraphy (Johnson et al., 1988)."
