Also known as Cumulus Hills

Where: Antarctica (85.2° S, 177.0° W: paleocoordinates 81.6° S, 69.5° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Lower Member (Fremouw Formation), Early/Lower Triassic (252.2 - 247.2 Ma)

• "lower portion of the Fremouw Formation, of Early Triassic age" (Colbert & Kitching, 1975);

•"The lowest vertebrate horizon is 13 m above the base. The Permian-Triassic boundary lies at the base or within the lower 13 m of the Fremouw Formation. [...] In the 1970 field season, [...] specimens were collected at 6 levels on bedding-plane surfaces, but exact stratigraphic position of each fossil was not recorded." (Collinson et al., 2006, GSA Bull. 118(5/6) p. 755; see also figs. 4 and 6 in that reference)

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial; medium-grained sandstone and gray, green mudstone

Size class: macrofossils

Preservation: mold/impression

Collected by J. W. Kitching, T. Rich, J. Ruben in 1970-1971; reposited in the AMNH, BPI

Collection methods: surface (in situ),

• "All specimens were collected by J. W. Kitching, except AMNH 9509, collected by Thomas Rich, and AMNH 9510, collected by John Ruben." (Colbert & Kitching, 1975)
