Stratigraphy
Geological group:Beaufort Formation:Katberg
Stratigraphy comments: "middle-upper Katberg Formation, Beaufort Group, Karoo Supergroup, uppermost
Lystrosaurus AZ (Kitching, 1977), late Early Triassic (Olenekian). [...] Kitchingnathus untabeni was most likely collected in the middle or upper horizons of the Katberg Formation, a stratigraphic assessment that is consistent with the presence of the index genus Procolophon at the locality. The occurrence of Procolophon in South Africa is restricted to the interval between the middle part of the Katberg Formation and the lowermost Burgersdorp Formation (Neveling, 2004; Smith and Botha, 2005; Botha and Smith, 2006)." (Cisneros, 2008).
Lithology and environment
Primary lithology:red sandstone
Lithology description: "bright red sandstone" (Cisneros, 2008)
Environment:fluvial indet. Tectonic setting:foreland basin
Geology comments: "It [the Katberg Formation] 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. African Earth Sci. 43)
Taphonomy
Modes of preservation:body,mold/impression

Museum repositories:BPI
Collectors:J. W. Kitching Collection dates:1952, 1966
Collection method comments: "Besides the holotype of Kitchingnathus untabeni, the locality Hobbs Hill has yielded several Procolophon trigoniceps specimens collected during field trips led by James W. Kitching in 1952 and 1966." (Cisneros, 2008).
