...EMESE M. BORDY; WILLIAM D. KRUMMECK Abstract An Early Triassic continental ichnofossil assemblage dominated by ∼ 4 cm diameter burrow casts was discovered in the transitional zone of the Katberg and Burgersdorp formations in the SE main Karoo Basin (Eastern Cape, South Africa). Analyses...

... (Stormberg Group) and corresponds to the entire Burgersdorp Formation. It is characterised by the presence throughout of the cynodont genus Cynognathus . The biozone reaches a maximum thickness of around 650 m in the southeast part of the basin and thins dramatically to the north, where it is only a maximum...

... been taken in the investigation of pre-boundary, trans-boundary, and post-boundary plant-fossil assemblages in the Karoo Basin, South Africa. Fourteen stratigraphic sections were evaluated in the Balfour and Normandien formations (Lower Beaufort Group), Katberg Formation, and overlying Burgersdorp...

... in the Balfour, Katberg and Burgersdorp formations respectively. This data shows that certain parts of the Beaufort Group stratigraphic succession that are present in the southern part of the Karoo Basin, are absent in the central Free State, indicating either a depositional hiatus or a period of erosion...

...Figure 2. Generalized stratigraphic section showing the litho- and biostratigraphy in the study area in the south of the Karoo Basin. The Katberg Formation is dominated by thick sandstone units, whereas mudstone is predominant in the overlying Burgersdorp Formation. The mandible indicates...

... Smith pers. obs.). Above the Swartberg member the uppermost Katberg Formation fines upwards into the Burgersdorp Formation, which contains the overlying Cynognathus Assemblage Zone ( Neveling, 2004 ). Neveling ( 2004 ) followed du Toit’s (1917 , 1918 ) initial proposal and placed the uppermost...

... ( Duncan et al. , 1997 ) by some sixty million years. The second reference quoted by Turner (1999 , Figure 14, p. 231) in support of laumontite in the Burgersdorp Formation (Beaufort Group) ( Fuller and Moir, 1967 ) at Sterkspruit, actually refers to authigenic analcite from the “Stormberg Red Beds...

...FIGURE 2 —General stratigraphic succession showing details of the Beaufort Group. The lower portion of the Burgersdorp Formation is approximately equivalent to the Driekoppen Formation ( sensu Groenewald, 1984 , 1996 ). Data based on Visser (1991) , Johnson et al. (1997) , and SACS (1995) ...

... unit should be correlated with the middle Katberg Formation because the lowermost and uppermost sections of the Katberg Formation are restricted to the proximal part of the basin. The predominantly argillaceous Burgersdorp Formation ( Johnson and Hiller 1990 ), which overlies the Katberg Formation...

... and lower part of the Burgersdorp Formation, however, are so poorly fossiliferous that prospecting of intraformational conglomerates is an attractive alternative (J. Neveling, personal communication, 2005). Identifiable fragments of temnospondyls and cranial materials of both Procolophon and Lystrosaurus...

... relatively arenaceous character when compared with 23 the adjacent Balfour and Burgersdorp formations (Groenewald 1996). Neveling (2004) 24 recognized an upward-thickening and -coarsening trend in the formation, culminating in stacked 25 cliff-forming sandstones in the middle to upper part. He proposed...

..., that is, similar in age to the Katberg or lower Burgersdorp formations (Early Triassic) of the MKB, as has been suggested for the Kingori Member (Manda Formation, Tanzania; Smith et al . 2018 ). We therefore tentatively consider the oldest potential age for Escarpment Grit sedimentation as Early–Middle Triassic...

... Triassic Burgersdorp Formation of South Africa. Both burrow occurrences have been attributed to cynodont therapsids. Burrows described there are, however, smaller and more circular in cross section than the Holy Cross burrows. The basic question is what organism is responsible for digging the Holy...

... Katberg and argillaceous Burgersdorp formations. The Katberg Formation is traditionally interpreted to represent fluvial systems deposited under more seasonally dry to semiarid conditions (e.g., Ward et al., 2000; Pace et al., 2009). It consists of a monotonous succession of fine- to very finegrained...
