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
