Leeukloof 43 (Permian of South Africa)

Also known as Leeuw Kloof, Leeuwkloof

Where: Western Cape, South Africa (31.9° S, 22.4° E: paleocoordinates 61.0° S, 30.2° W)

• coordinate based on political unit

• small collection-level geographic resolution

When: Tropidostoma Assemblage zone, Hoedemaker Member (Teekloof Formation), Wuchiapingian (259.9 - 254.2 Ma)

• "Tropidostoma Assemblage Zone, middle Tatarian" (Modesto & Smith, 2001); "The new Youngina locality is [...] within a regionally extensive mudrock sequence (informally termed the Hoedemaker member) that forms part of the Teekloof Formation of the lower Beaufort Group (Adelaide Subgroup)." (Smith & Evans, 1995). The Tropidostoma AZ is Wuchiapingian according to Catuneanu et al. (2005, Afr. J. Earth Sci. 43) and is "previously known as the lower Cistecephalus Zone of Kitching (1977)." (Smith & Evans, 1995).

Environment/lithology: dry floodplain; claystone and siltstone

• " [...] semi-arid floodplain. The host sediments are interpreted as having accumulated on the proximal floodplain of a large meandering riverchannel (Smith, 1993)."

Size class: macrofossils

Preservation: permineralized

Collection methods: SAM = South African Museum, Cape Town

Taxonomic list

• In Smith and Evans (1995) only the name "Youngina", always without the specific epithet, is applied to the specimen SAM K7710, but in a later paper (Palaeontology 39(2), 1996), these authors explicitly state that it represents Y. capensis (here not considered to be a true re-identification).
