Also known as Oliviershoek Pass, Lystrosaurus zone

Where: KwaZulu-Natal, South Africa (28.6° S, 29.1° E: paleocoordinates 66.3° S, 10.8° W)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Lystrosaurus other zone, Verkykerskop/Driekoppen Formation (Beaufort Group), Induan to Induan (252.3 - 247.2 Ma)

• "very high in Lystrosaurus-zone beds";

•Lithostratigraphy original entry was: Group = Karoo; Formation = Beaufort Series; modified according to Catuneanu et al. (2005, Afr. J. Earth Sci. 43) and Claassen (2008, S. Afr. J. Geol. 111(23));

•Note: The locality unquestionably lies within the Tarkastad Subgroup of the Beaufort Group whose outcrop is quite narrow in the area so that it is not divided into formations on the map given in Catuneanu et al. (2005 fig. 24). The Tarkastad Subgroup in northwestern Natal (and northeastern Free State) comprises the Verkykerskop and Driekoppen Formations (Claassen, 2008).

• member-level stratigraphic resolution

Environment/lithology: terrestrial; siliciclastic sediments

Size class: macrofossils

Collected by Kitching in 1957; reposited in the BPI

• Though not specifically stated, the Brink specimens are probably BPI.

•Sigogneau specimen is BPI. Tetracynodon has a different Field Number than that given in Brink 1965, but Brink states that Tetracynodon was found four feet away from Oliviera parringtoni.
