We report the occurrence of a mammalian lumbar vertebra and several associated fish teeth from Dillai Parbat, in the southeastern part of the Mikir Hills of Assam, in northeastern India. The specimens were recovered from a shallow marine limestone unit of upper middle Eocene age (40-37 Ma). The vertebra is tentatively described as that of an archaeocete cetacean. This is the first report of Eocene vertebrates from the northeastern part of India, and it significantly expands the geographical distribution of Eocene marine mammals of India. Further fieldwork is required to assess the potential of this new locality.

Thirty species of planktic foraminifera encompassing the Campanian-Maastrichtian stages to Paleocene epoch are reported and briefly described for the first time from the vicinity of the 85° East Ridge in the Mahanadi offshore. These include the Late Cretaceous (Campanian-Maastrichtian) forms such as Abathomphalus mayaroensis, Globotruncanita stuarti, Globotruncana aegyptica, Racemeguembelina fructicosa, Rosita contusa, Pseudotextularia elegans and early-middle Paleocene age markers such as Globoconusa daubjergensis, Morozovella pseudobulloides, M. uncinata and Planorotalites compressa. Two planktic biozones- the Abathomaphalus mayaroensis zone and Guembelitria cretacea (P0) zone and two subzones- Subbotina triloculinoides - Globanomalina compressa (P1b) and Praemurica inconstans - Praemurica uncinata (P1c) are identified for the first time in the basin. Planktic foraminiferal assemblage and range suggest possible hiatuses of Pα and P1a (early Danain) and late Paleocene (P3-P4) in the area.
