1996-97 - Birbal Sahni Institute of Palaeobotany

BSIP
(FET-replacement, etc.) was carried out. Residual spectra were recorded with
Quadropole and the 180' mass spectrometer.
Visited Mandla area in Madhya Pradesh and collected a number of trap and
fossil wood specimens including a fossil stem with roots as well as one with attached
branch.
PROJECT 9 ANNOTATED ATLASES, CATALOGUES, MONOGRAPHS
AND BOOKS AND RESEARCH PROGRAMMES AD
F1NUM
Programme 9.1 Data bank for Palaeozoic-Mesozoic palynology, using expert
system and compilation of catalogues, atlases and
other palynological information
Archana Tripathi, Vijaya & Ram-Awatar
The FADs of certain significant palynotaxa have been evaluated in the
delimitation of stratigraphic units through Permian sequence on peninsular India. FADs
of Jayantisporites eonatus and Parasaeeites dellsicorptls delimit the base level of Talchir
Formation. The coal deposits of Permian Period are classified as Karharbari and Barakar
Formations. The initiation of these deposits can be easily identified by the LAD of
Parasaeeites densicorptls at the beginning of Karharbari and FAD of Dellsipollenites
magnieorptls at the top of Kulti Formation. The FADs of the Index species
Arcuatipollenites pellueidtls, Kamthisaecites kamthiellsis, Ltllldbladispora brevietlla
and Playfordiaspora ealleellosa gradually herald the transition from Late Permian
carbonaceous sediments into khaki-green facies of Early Triassic (Panchet Formation)
demarcating the Raniganj-Panchet formational boundary vis-a-vis P/Tr.
Programme 9.2 : A catalogue of fossil dinoflagellates from India
Khowaja-Ateequzzaman & Rahul Garg
Stratigraphic distribution of dinoflagellate cyst taxa from Cretaceous-Tertiary
sedimentary sequences of India is being compiled for preparation of computer data
base.
Programme 9.6 Patterns of leaf architecture and cuticle in some tropical
dicotyledonous families
D.C. Saini
Leaves of Ficus religiosa, F benghalensis, F rettlsa, F glomerata, F illfeelOria,
F hispida, F benjamina, F eomosa, F mysorensis, F tsiela, F trigona and F elastica
were collected and identified. Herbarium sheets of these species were prepared.
Duplicate specimens were treated with chemicals and prepared the slides of cuticle
and laminated mount of leaf venation patterns. An atlas of leaf print was also prepared.
