Fossils 'B1', Lower Bone Bed, Chiweta (Permian of Malawi)

Where: Northern Region, Malawi (10.7° S, 34.2° E: paleocoordinates 55.3° S, 14.7° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Cistecephalus Assemblage other zone, Chiweta Beds Formation, Wuchiapingian (259.9 - 254.2 Ma)

• Correlated to the Cistecephalus Assemblage Zone of South Africa, of early late Permian (Wuchiapingian) age: "the overlapping ranges of Endothiodon and Oudenodon, consistent with the presence of Gorgonops ?dixeyi and Aelurognathus, argue for a lower Cistecephalus Assemblage Zone placement for the Chiweta Beds" (Jacobs et al. 2005)

• group of beds-level stratigraphic resolution

Environment/lithology: terrestrial; lithology not reported

Size class: macrofossils
