The paper outlines the preliminary results of a palynological study of a carbonaceous phyllite sample from the B Member of the Jutogh Formation of Simla hills. Systematic descriptions are given for 5 genera and 6 species of acritarch assemblage recovered. Among the species described, five are new. Microfloral evidence favours a Lower Cambrian age for the bed.- Mesozoic-Cainozoic Boundary in Assam

The vertical distribution of significant phytoplankton, spore-pollen and foraminiferal guide fossils are detailed with special reference to palyno-stratigraphic investigations in the South Shillong Plateau. The diagnostic features of the Maestrichtian-Danian-Palaeocene intervals are summarised. Biostratigraphic evidences favour the placing of the Mesozoic-Cainozoic boundary between the Mahadeo Formation (Maestrichtian) and the overlying Langpar Formation (Danian).- Yong Limestone of Tethys Himalaya- Its Stratigraphic Status and Palynological Fossils

Stratigraphic status of Yong Limestone has been formally instituted following the Code of Stratigraphic Nomenclature of India. A reasonably rich palynological assembIage, consisting of 11 Chitinozoan and 9 scolecodont forms, have been recorded from this stratal sequence. Chitinozoan evidence indicates that Yong Limestone may be a time transgressive unit. The Ordovician-Silurian boundary perhaps lies within the lower part of this formation.- Fundamentals of Historical Geology and Stratigraphy of India
