Two tiny carapaces having strong resemblance to Ostracoda are reported from the basal part of the upper Krol Formation occurring in the Nainital Synform of U. P. Himalaya. These ostracode forms are present in close association with several forms of shelly microfauna distinctive of Tommotian (early Cambrian) time. The characteristic features of these two forms representing the oldest ostracodes of the Indian subcontinent are described.Keywords

This paper reports the find of a new non-mammalian cynodont from the Lower Triassic Panchet Formation of the Damodar valley, West Bengal, India. The fossil, recovered from a clay pellet rich calcareous sandstone bed, is a part of left lower jaw having five post canines that are damaged to various extents. A combination of mammal-like advanced characters such as much enlarged dentary, reduced post dentary bones, high coronoid process, large masseteric fossa, each post canine with a large central cusp flanked by a distal and a mesial accessory cusps with two additional lingually positioned cingular cusps, incipient ischolar_main division and clearly demarcated crown-ischolar_main juncture prompted to erect a new taxon Panchetocynodon damodarensis gen. et sp. nov.Keywords
