Lower Maleri Formation

The Lower Maleri Formation is a sedimentary rock formation found in Andhra Pradesh and Telangana, India. It is the lowermost member of the Pranhita–Godavari Basin. It is of late Carnian to early Norian age (Upper Triassic), and is notable for its fossils of early dinosaurs, including the basal saurischian (possible theropod) Alwalkeria.[1]

Correlations

The formation has been correlated with the Molteno Formation (Karoo Basin) and Pebbly Arkose Formation of Africa, the Santa Maria Formation of the Paraná Basin in Brazil, the Ischigualasto Formation of the Ischigualasto-Villa Unión Basin of Argentina and the lowermost Chinle Formation of North America.[6]
