The Upper Maleri Formation is a sedimentary rock formation found in Telangana, India. It is one of the formations of the Pranhita–Godavari Basin. It is of late Norian and possibly earliest Rhaetian ages (Late Triassic), and is notable for its fossils of early dinosaurs.

Vertebrate fauna[]

Angistorhinus sp., cf. Leptosuchus, Aetosauria indet., a guaibasaurid ( R277) and 2 basal dinosauriforms (ISI R282, 284) have also been recovered from it.[1]
