Abstract

The present paper deals with a detailed study of the petrified woods belonging to Polyalthia, Anisoptera, Dipterocarpus, Cynometra, Cassia and Diospyros collected from the Lower Siwalik beds of Kalagarh, district Bijnor in Uttar Pradesh. These are Polyalthioxylon indicum sp. nov., Anisopteroxylon kalagarhensis sp. nov., Dipterocarpoxylon parabaudii sp. nov., Cynometroxylon sp. cf. C. indicum Chowdhury & Ghosh, Cassinium borooahii (Prakash) Prakash, and Ebenoxylon miocenicum sp. nov. Present distribution of the modern equivalents of these fossil species indicates a more humid climate in this region during the Lower Siwalik period.
