This paper explains the provenance of Upper Jurassic (Kimmeridgian sediments) exposed in the Eastern part of the Kachchh Basin (Tapkeshwari temple section) western India, on the basis of petrographic study of rock samples and fossils (Trace fossils) found in the field. This study also investigates the compositional variation of the sandstone with reference to the evolution of the Kachchh Basin, which commenced as a rift basin during the Late Triassic and emerge into a passive margin basin in the end of Cretaceous. This study analyzes sandstone samples of Tapkeshwari temple section, trace fossils and other structures found in the field. According to petrography study of Tapkeshwari temple section it has been observed that sandstone is mostly medium grained and laminated, shale beds also present with intercalations, quartz grains are mostly subrounded to subangular, packing of grains is generally moderately to well packed, trace fossils found in lower beds of the section. Cementing material is mostly Ferruginous. Ripple marks present and Ophiomorpha trace fossils found. Ophiomorpha trace fossil assemblages is characterised by moderate bioturbation and low trace fossil diversity. Ophiomorpha ichnofossil indicates continent to sea shore environment.
