Etjo Nord, EN-3 (Triassic to of Namibia)

Where: Namibia (21.1° S, 16.4° E: paleocoordinates 54.0° S, 9.9° W)

• coordinate estimated from map

• small collection-level geographic resolution

When: Cynognathus subzone C other zone, Upper Member (Omingonde Formation), Anisian to Anisian (247.2 - 235.0 Ma)

• Locality EN-3 is stratigraphically very high in the upper Omingonde Formation (see Abdala & Smith 2009: fig. 11). 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 collection would therefore be late Anisian or early Ladinian in age.
