Geologic formation in India
The Lower Dharmaram Formation is a sedimentary rock formation found in Andhra Pradesh, India. It is one of the formations of the Pranhita–Godavari Basin. It is of latest Norian and Rhaetian ages (Upper Triassic), and is notable for its fossils of early dinosaurs.
Vertebrate fauna
cf. Paratypothorax, cf. Nicrosaurus, fragmentary remains of sauropodomorphs (ISI R279, 280, 281) and neotheropods (ISI R283) have also been recovered from it.[1]
Correlations
The formation has been correlated with the Lower Elliot Formation (Karoo Basin) and Forest Sandstone of Africa, the Caturrita Formation of the Paraná Basin in Brazil, the Laguna Colorada and Los Colorados Formations (Ischigualasto-Villa Unión Basin) of Argentina, the Chinle Formation of North America, the Trossingen Formation of the Keuper of Germany, and the Nam Phong Formation of Thailand.[3]
