Mt Etjo, general (Triassic of Namibia)

Where: Namibia (21.1° S, 16.5° E: paleocoordinates 53.7° S, 11.7° W)

• coordinate estimated from map

• local area-level geographic resolution

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

• "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; a younger 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. These specimens of Dolichuranus were probably from the older fauna and would be early Anisian in age

• formation-level stratigraphic resolution

Environment/lithology: terrestrial; shale and conglomerate

Size class: macrofossils
