Coordinates: 31.9° South, 22.4° East (view map)
Paleocoordinates:61.0° South, 30.2° West
Basis of coordinate:based on political unit
Geographic resolution:small collection
Time
Period: Permian Epoch: Lopingian
Stage: Wuchiapingian 10 m.y. bin: Permian 4

Age range of interval: 259.51 - 254.14 m.y. ago
Stratigraphy
Geological group:Beaufort Formation:Teekloof Member:Hoedemaker
Stratigraphy comments: "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).
Lithology and environment
Primary lithology: claystone
Secondary lithology: siltstone
Includes fossils?Y
Includes fossils?Y
Environment:dry floodplain Tectonic setting:foreland basin
Geology comments: " [...] semi-arid floodplain. The host sediments are interpreted as having accumulated on the proximal floodplain of a large meandering riverchannel (Smith, 1993)."
Taphonomy
Modes of preservation:body,permineralized
Size of fossils:macrofossils
Articulated whole bodies:none
Temporal resolution:snapshot
Spatial resolution:autochthonous
Collection methods and comments
Collection methods:field collection
Reason for describing collection:taxonomic analysis
Collection method comments: SAM = South African Museum, Cape Town
Taxonomic list comments: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).
