Occurrence of anonidium-like pollen in the tura formation (palaeocene) of Meghalaya, India

Abstract

Anonidium-like pollen of the family Annonaceae was recovered from the Nangwalbibra section of Tura Formation (Palaeocene), Meghalaya. LM and SEM studies of living and fossil pollen reveal that they are closely similar in apertural disposition and ornamentation pattern. Anonidium is confined to West Africa at present. The probable route of migration of this genus to India from elsewhere is discussed.
