Abstract

The fossil i.e. Leaves impression of Michelia butanensis (Magnoliaceae), Gyocardia mio-odorata (Flacourtiaceae), Zizyphus aenoplica (Rhamnaceae) and Butea siwalicus (Fabaceae)were collected from the Siwalik Sediments (Formation-II) near Darranga and Lakshmi river section in Bhutan for detailed systemic study. The habit, habitat and present day distribution of the comparable extant taxa indicates the existence of tropical to sub-tropical evergreen to semi evergreen forest with humid climate in the area during the deposition of the Siwalik sediments.
