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 (ISI R277) and 2 basal dinosauriforms (ISI R282, 284) have also been recovered from it.[1]

Correlations
The formation has been correlated with the Forest Sandstone of Africa, the lower Caturrita Formation of the Paraná Basin in Brazil, the upper Ischigualasto Formation and lower Los Colorados Formation of the Ischigualasto-Villa Unión Basin of Argentina, and the Chinle Formation of North America.[2]
