Also known as Grass Ridge, Grassridge

Where: Eastern Cape, South Africa (31.8° S, 25.4° E: paleocoordinates 65.0° S, 23.6° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Katberg Formation (Beaufort Group), Induan (252.2 - 251.2 Ma)

• "lowermost triassic"; see also comments on locality

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; limestone

• "The type of Noteosuchus colletti is preserved in a roughly circular block of waterworn limestone, termed a 'nodule' by early describers"

Size class: macrofossils

Collection methods: mechanical,

• "Because the matrix was exceedingly hard and the bone comparatively soft, it was decided rather to remove the bone mechanically. This resulted in the exposure of extremely high fidelity moulds of both dorsal and ventral surfaces. These were cast with liquid latex."
