Gymnosperm fossil woods from gangta bet, Eastern Kachchh, Western India

Two gymnospermous fossil woods Araucarioxylon wagadensis n. sp. and Podocarpoxylon gangtaensis n. sp. have been described for the first time from the younger part of the Gadhada formation exposed around the core of the central dome of the Gangta Bet. The ammonites recorded from the Gangta Bet by earlier workers suggest that these fossil woods come from Callovian sediments forming the basal part of the succession. These fossil woods are characterized by the presence of early and late secondary wood with small resin canals, tracheidal cells, aurocaroid or podocarpoid pits in cross field area. Dendrological data indicate that the climate was characterized by cycles of tropical wet and dry savanna climate.
