Donnybrook (Queenstown District) (Triassic to of South Africa)

Also known as Donnybrooke; Tafelberg; Swart Kei River

Where: Eastern Cape, South Africa (32.1° S, 26.5° E: paleocoordinates 66.5° S, 21.2° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Katberg Formation (Beaufort Group), Induan to Induan (252.2 - 247.2 Ma)

• Somewhere between the middle part of the Katberg Fm. and the lowermost part of the overlying Burgersdorp Fm. because this is the interval (upper Lystrosaurus Assemblage Zone) to which Procolophon is restricted (see, e.g., Cisneros, 2008, Paleoworld 17(2)).

•Cisneros (2008, Palaeont. Afr. 43), based on Kitching (1977), suspects all Procolophon specimens from Donnybrook to come "from the same localized band of dark red mudstone, approximately one metre thick, within the Katberg Formation."

• bed-level stratigraphic resolution

Environment/lithology: fluvial; red mudstone

• The Katberg Fm. "was deposited under arid climatic conditions within the more distal parts of a sandy, bedload-dominated, ephemeral braided stream complex draining a source area composed predominantly of granitic, metamorphic and alkaline volcanic rocks (Hiller and Stavrakis, 1984; Smith, 1995)." (Catuneanu et al. 2005, J. Afr. Earth Sci. 43(1-3)).

Taxonomic list

• Carroll & Lindsay (1985) list two non-type specimens from Donnybrook, reposited in the BMNH, but do not state whether these are part of the material already mentioned by Broom (1903) and Seeley (1905). Since this cannot be ruled out, these specimens here are are not added to but are regarded as to be included in the material already reported by the latter authors.
