Lower Maleri Formation

Lower Maleri Formation
Stratigraphic range: Late Triassic (late Carnian – early Norian)
Type Geological formation
Location
Region Asia
Country India

The Lower Maleri Formation is a sedimentary rock formation found in Andhra Pradesh, 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]

Vertebrate fauna

cf. Angistorhinus and cf. Typothorax have also been recovered from it.[2][3]
