Abstract
Previous work on the fauna and flora of the Cambay shale underlying as well as inter-bedded within the lignite seams of Vastan lignite mine, Gujarat allows the shale to be assigned a Lower Eocene age. However, there is no record of occurrence of any fossil from the sedimentary beds succeeding the shale-lignite sequence that might fix upper age limit of the Cambay shale. We record a characteristic Middle Eocene ostracod assemblage from the Nummulitic marl/limestone, immediately overlying the shale-lignite sequence from the Tadkeshwar lignite mine close to the Vastan lignite mine. The assemblage comprises 22 species, many of which widely occur in the Middle Eocene beds of Kachchh, Rajasthan and adjacent areas of Pakistan.
