Abstract

The lithostratigraphy, depositional environment and age of the Marwar Supergroup have been reviewed in the light of report of δ 13C depletion recorded in the carbonates of the Bilara Group (middle part of Marwar Supergroup) and discovery of trilobite-like trace fossils from the "Red beds" of Nagaur Group (upper part of Marwar Supergroup). The δ 13C depletion observed in Bilara carbonates is not a result of glaciation rather due to rapid burial and poor water circulation in the low energy water of the protected basin. Secondly, the trace fossils are, in fact, traces of notostracan crustaceans found in shallow fluvial and shallow lacustrine environment. The present paper also records a spiral, burrowing trace-fossil, possibly Gyrolithes, from a cross-bedded sandstone of the Jodhpur Group.
