N slopes, Etjo Mtn, below lower arenaceous layer (Triassic of Namibia)

Where: Namibia (21.1° S, 16.5° E: paleocoordinates 53.6° S, 11.7° W)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Cynognathus subzone B other zone, Omingonde Formation (Karoo Group), Anisian (247.2 - 242.0 Ma)

• Referred to as the "Lower Etjo Beds" by Keyser (1973) but now called the Omingonde Formation. "Based on the co-occurrence of Kannemeyeria and Erythrosuchus in subzone B of the Cynognathus Assemblage Zone, the Omingonde Formation may be broadly assigned an Anisian age." (Damiani et al. 2007. Palaeontology 50: 1531-1546)

•Abdala & Smith (2009) suggest the possibility of two different faunas in the upper Omingonde Formation; an older one corresponding to Cynognathus Subzone B and the upper possibly to Cynognathus Subzone C. On the basis of the presence of Chiniquodon in the upper fauna, Abdala & Smith (2009) tentatively suggested that the Omingonde could extend into the early Ladinian. This temnospondyl was suggested by Abdala & Smith (2009) to come from the older fauna, and would therefore be early Anisian in age.
