• outcrop-level geographic resolution

When: Cynognathus Assemblage Zone Subzone C other zone, Lifua Member (Manda Beds Formation), Anisian (247.2 - 242.0 Ma)

• Lifua Member of the Manda beds is "correlated with Subzone C of the Cynognathus Assemblage Zone. This correlation was based on the shared occurrences of the dicynodont Angonisaurus and the cynodonts Diademodon and Cricodon. Subzone C of the Cynognathus Assemblage Zone is suggested to be late Anisian. The Rio Mendoza Formation of Argentina correlates with Subzone C of the Cynognathus Assemblage Zone(Rubidge 2005), and thus the Lifua Member of the Manda Beds. The top of the Rio Mendoza Formation has been dated at 243 ± 5 Ma (Avila et al. 2006), which is consistent with the Anisian age as predicted by biostratigraphy."
