We report here, a fossil palm leaf from Lower Siwalik sediments, tied to nearby palaeomagnetically dated 11.2 Ma old beds exposed in the Baner Khad, near Ranital, Himachal Pradesh. The palm fossil leaf impression has been placed in the genus Palmacites sp. (Family: Arecaceae) based on its diagnostic features such as large palmate leaf without hastula and costa (midrib), showing coriaceous texture, leaflets diverging from the base of the lamina with prominent midrib and parallel venation. This finding may indicate presence of tropical to subtropical climatic conditions in the Himalayan foothills around Kangra Valley in the Middle Miocene time.Keywords
Palm Leaf, Siwaliks, Kangra, Himachal Pradesh.
