Lower Maleri Formation (India) | |
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]
Vertebrate fauna
[edit | edit source]cf. Angistorhinus and cf. Typothorax have also been recovered from it.[2][3]
