Trail Canyon, Panamint Mountains (Loc. 2 of Elliott and Ilyes 1996) (Devonian of the United States)

Where: Inyo County, California (36.3° N, 117.0° W: paleocoordinates 25.9° S, 58.2° W)

• coordinate estimated from map

When: Lippincott Member (Lost Burro Formation), Eifelian (393.3 - 387.7 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.

Environment/lithology: estuary or bay; dolomitic, cherty/siliceous sandstone and dolomitic siltstone

• The vertebrate-bearing unit is characterized by interbedded dolomitic siltstones and sandstones, quartzite, and pebble conglomerates with clasts of dolomite. Some nodular chert is also present.

Size class: macrofossils

Preservation: mold/impression

Reposited in the FMNH
