Fossils

Plant fossils are: Glossopteris longicaulis, Gangamopteris sp., Glossopteris sp., and G. indica Schimp. Maithy et al., (2006) reported Gangamopteris cyclopteroides , G. intermedia, Glossopteris augustifolia, G. communis, G. damudica, G. intermittens, Scutum cf. stowmanum, Vertebria indica, etc from the Bhareli Formation exposed between Pinjoli Nala and Sessa along the Bhalukpong-Bomdila Road, West Kameng district, Arunachal Pradesh.


Age 

Based on the Lower Gondwana plant fossils assemblage, Maithy et al., (2006) suggested Early Permian age.
