To coordinate with other knowledge centres in areas of mutual interest, suchas early life, exploration of fossil fuels, vegetation dynamics, climatic modelling,conservation of forests, etc; andDssemination of palaeobotanical knowledge.During the early phase the research activities of the Institute laid emphasis oncomposition of the Indian fossil floras, the form and structure of different taxa, andtheir distribution in time and space. Gradually, the research activities diversifiedtoencompass palynological and biopetrological studies for building past history ofvegetation and also to understand the genesis and palaeoecology of coal basins.Attention was also paid to phylogeny and evolution. Biostratigraphic dating ofsediments, correlation of surface and subsurface sections and location of favourableareas for oil prospecting assumed added importance. Ultrastructural studies formorph;>taxonomy have recently been introduced with the availability of a scanningelectron microscope. Investigations on biodiagenesis have been given due importanceto undcrstand factors responsible for the degradation of dispersed organicmatter. Keeping in view the importance of absolute dating of palaeobotanical andarchaeological samples geochronological studies also have been taken up.In order to attain wider interaction among scientists at the Institute as well asto increase inter-institutional collaboration, increasingly more emphasis has beenlaid on multidisciplinary approaches. It has also been made a guideline for futureplanning. The application of this concept has substantially increascd the precisionand accuracy of results.Current research activitics are organised under the following projects withmany programmes under each projects:1. Antiquity, radiation and evolutionary patterns of early biota2. Gondwana coal and associated sediments: genesis, floral evolution andbiostratigraphy3. Cenozoic plant biogeography of peninsular India4. Phytoplankton biostratigraphy of marine sedimentaries of India5. Palaeo floristic diversification in the Himalayan region6. Biostratigraphy and palynofacies of petroliferous basins of east India7. Reconstruction of Quaternary vegetational patterns8. Geochronometry of Indian rocks9. Annotatcd atlascs, catalogues, monographs, and booksClose in teraction with other cen tres of learning in the country helped to achievetangible results. Some of the research findings during the year 1991-1992 include:Early to Middle Riphean stromatolite morphotypes Conophyton, Strati/era undosa,Gym n osolen, Strati[era undata, Kussiella, Jacutophyton, Tungussia, etc. have(ii)

een recorded from the Cudapah Basin. Digitate stromatolites show varicd types ofmicrostructures from filamentous to rugged nature indicating the role of coccoidand filamentous cyanobacteria in development of the respective microstructure.The ginkgopsid and glossopterid association in the flora from the Datum fircclayquarry of Auranga Coalfield suggests similarity with the ginkgopsid richassemblage of the Lower Permian sediments of Rajmahal Hills, Bihar. Studies onevolutionary lineages in various leaf forms and fructifications of glossopterid indicatedevelopment of glossopterid group of plants along two different lineages. Anew tripinnately branched fern-like foliage Maheshwariopteris digitata is reportedfrom shales associated with Lalmatia coal seam in the Hura Coalfield, RajmahalBasin. Megafloristic investigation of Khutnashi assemblage has revealed that it isolder than Gilamari and Chunakhal floras. It resembles the flora of 2nd intertrappeanbed at Bhutahapahar, Rajmahal Hills. The Mamal Formation, of thePanjal Group in Kashmir has been redefined.Palynological analysis of bore-hole SPB-18 from Middle Pali sequcnce ncarBurhar arca, Sohagpur Coalfield shows a Late Permian palynoassemblage whichrcveals a closer relation with the assemblage from Raniganj Formation. Presenceof Leiosphaeridia in few samples indicates a probable marine influence in this area.The palynological analysis of samples from 450 m deep bore-hole TCW-25 in thenorthern part of the Talcher Coalfield has revealed the presence of three distinctpalynoassemblages based on FADs, LADs and pattern of species distribution.They are comparable to the marker Assemblage zones identified in Damodar­Rajmahal area. The lowermost assemblage - Parasaccites korbaensis AssemblageZone represents the Upper Talchir, and Scheuringipollenites barakarensis AssemblageZone and Faunipollenites varius Assemblage Zone represent Lower andUpper Barakar, respectively. Based on evolutionary changes in the morphology ofthe pollcn groups, their FADs and LADs, eleven Biohorizons and ten lnvcrval zoneshave been identified through the span of Gondwana sequence. Analysis of data onPermo- Triassic boundary has revealed that there had bcen no mass extinction at thisboundary. It was an cpisode of high turnover. The climatic changes and alterationin geomorphology due to new tectonic-setup at the boundary wcre responsible fora major shift in evolution of palynomorphs. Eight palynoevents h~ve been identifiedalong the latest Permian-earliest Triassic transition and they have been tagged withcomparable palynoevents in various basins of the peninsula. Palynoflora I patternsstudied in bore-holes GS-l,2,3 and 4 from Sattupalli area have shown the presenceof Late Permian palynoassemblages. The assemblage is characterised by the presenceof slriate disaccates.Microconstiluents of the coals from Lalmatia colliery have been estimated tounderstand the ratios between various reactive and non- reactive contents. It hasbeen observed that the coals are rich in trimaccrite and of (mixed) type, indicatinginferior quality for selective utilization. A detailed megascopic study of various coalbands indicates that the Talchir coals are mostly composed of hard dull bands. Theyalso soil the finger due to the presence of fusion at various levels, suggestingfluctuating hydrological conditions in the basin. First authentic record of Botryococcusalga (alginite) from Singrauli coals has been made. A scheme for indexingspontaneous combustion susceptibility of Indian coals and lignites has been pro-(iii)

posed, which incorporates most of physical, chemical and petrological factorsrecognized to have induced spontaneous heating process.A rich assemblage of leaf-impressions from Arjun Khola were identified andassigned to the genera, viz., Ag/aia, Alstonia, Alsodeia, Anacolosa, Artocarpus,Bridelia, Diospyros, Dracontomelum, Euphoria, Evadea, Filicium, Garcinia, Grewia,Gynocardia, Lagerslroemio, Lepionurus, Miliusa, Mil/ellia, Phyllanthus, Unona, Vitis,etc. of the dicotyledonous families. Two fabaceous fruits have been identified wilhthose of Butea superb a and Sindora velutina. Fossil woods of Dipterocarpus(Dipterocarpaceae), Canarium (Burseraceae), Euphoria, (Sapindaceae), Julbernardia,(Fabaceae), Barringtonia (Leeythidaeeae), Madhuca and Manilkara(Sapotaceae) have been identified from Namsang beds near Deomali, ArunachalPradesh. Of these, Julbernardia is an African genus and suggests phytogeographicallinkage of Africa with the Indian subcontinent during Neogene. A leaf of Mangi[erarecovered from the Upper Palaeocene sediments near Laitryngew, Khasi Hillssupports the view that the genus Mangi[era appeared first in the Upper Palaeocenein the Indian subcontinent. A fossil wood similar to Grewia (Tiliaceae) with tilecells and radial gum canals has been identified. Woods similar to African generaTrichilia (Meliaceae), Blighia (Sapindaceae) and Erythr01ylon (Erythroxylaceae)were also identified from Nawargaon. The genus Chlorophora of the familyMoraceae, a typical African genus, has been recorded for the first time in the IndianNeogene flora of western India.Morphotaxonomic study of the palynoflora obtained from the Neyveli Mine-lhas been partly done. The assemblage is correia table to the upper zone of theNeyveli Formation, viz., Trilatiporites sellingii Cenozone of Jayamkondacholapuramarea. Latest Maastrichtian, low latitude calcareous nannoplankton marker speciesMicula prinsii has been reported in this section, terminating in stratigraphic orderat the base of the clay layer. An in tegra ted scheme, incorporating dinoflagellate cyst,calcareous nannoplankton, planktonic foraminifera and geochemical data, is proposedfrom the Langpar Formation exposed along the western bank of the UrnSohrengkew River, on the southern slope of Cherrapunji Plateau, Khasi Hills.Three new species of the genus TrichodiniunJ, viz., T. minulum, T. brevispinosum, T.jainii and a new combination Acanlhaulax magnum (Jain) are described from theGrey Shale Member of Dalmiapuram Formation (Lower Albian) together with anew genus Ectodinium and a new species, Callaiosphaeridium tapeum fromTrichinopoly Formation (Turonian-Santonian) of Cauvery Basin. A rich dinoflagellatecyst and acritarch assemblage has been recovered from selected core andcUlling samples of a 764.9 meter deep bore hole drilled in Puduvoyal, ChingleputDistrict, Palar Basin, southern India and assigned an Early Cretaceous (Hauterivian-Barremian)age. Middle Miocene diatoms from the 75 meter thick South CoastCliff Seclion of Kamorta Island have been detailed out. Palynoassemblages of fourmeasured sections, viz., Dali, Khargala, Sair and Kalakot of Jammu depict theirclose similarity with those recorded from Kalka-Simla and Banethi-Bagthan areasof Himachal Pradesh. Based on this observation a possible sea-link between thesetwo widely separated areas is envisaged during Eocene time. Palynological investigationon the Cretaceous-Tertiary transition in the bore hole core no. CM5 drilledin the Atlantic occan off Senegal Coast, West Africa suggcsts a major change infloral composition marking Krr boundary, characterized by the disappearance of(iv)

Maastrichtian marker taxa and presence of a fern spike.••Pollen analytical investigation of 12 glacier dust samples from Dunagiri Glacier,Garhwal Himalaya revealed presence of broad-leaved Quercus, Betula, Alnus, Carpinus,Ulmus and Celtis, Pinus, Abies, Picea and Cedrus in low values. Poaceae,alongwith Cheno/Ams, Ranunculaceae, Asteraceae, Rosaceae, etc. are the prominentherbaceous elements. Palynology of 4.30 meter deep profile dated 3800 yearsB.P. from Rambha on south east flank of Chilka Lake enabled to divide whole timespan into two phases, between 3,800 - 2,000 yrs. B.P. records the existence of welldeveloped core-mangrove forest and from 2,000 yrs. B.P. till date records the overalldegradation of core- mangrove vis-a-vis uprise in the values of hinterland taxa. Treesamples of Cedrus deodara from Harshil in Uttarka'shi have been dated and a 745yrs long (1243-1987) chronology has been prepared. Another chronology of Pinuswallichiana growing in sub-alpine mesic site in Gangotri ranges from 1694 - 1988AD. The occurrence of hemplbhang (Cannabis sativa) charcoals from Neolithic­Chalcolithic site at Senuwar, Rohtas, Bihar (Ca 2000-600 B.C.) suggests the exploitationof narcotic properties of this plant. The occurrence of pomegranate (Punicagranatum) from Rohira, Punjab (ca. 2000 - 1700 B.C.) suggests the cultivation ofpomegranate in the orchard husbandry of Harappans.A core of lake deposit from Orissa relating to the study on the evolution ofmangrove vegetation was dated to 3470 ± 170 yrs at a depth of 3.5 m. A carbonaceousocean-sediment core from Andaman Sea was dated using the organic fractionof the sediment. The C-14 age at a depth of 33 cm is 11850 yrs and at 1.0 m it is­21000 yrs. Charcoal samples relating 10 archaeological studies from Mesolithicculture of Kerala has been dated for the first time at 2850 ± 80 yrs B.P. Petrifiedwood samples collected from Deccan Intertrappean beds have been dated using theAuto Scan system; the F-T ages of petrified woods from different localities nearShahpura in Mandla district, Madhya Pradesh are Ghghua: 57 ± 8 ma, Umaria: 56±7 ma, Silther: 53 ± 9 ma, Parapani: 54 ± 7 ma and Mehdwani: 58 ± 8 ma.The Research Programming and Planning Group consisting of Drs H.P.

The Symposium inaugurated by Professor Alfred Traverse of PennsylvaniaState University, had an International participation. Professor Traverse remarkedthat pal- aeobotanists are sort of historians. St udy of plant fossils in co-ordinationwith other sciences, such as organic geochemistry, animal/plant interaction, etc.,can give us a new insight into evolutionary biology. 1\venty- three oral presentationswere made at this symposium. As of today, typescripts of 19 papers havealready been received. Nine more are promised, that include papers that wereinvited but could not be presented. Editing of the papers is in progress. We hopeto release the volume on 14 November 1992.Symposium on Four Decades orIndian PalaeobotanyThe Symposium was organized with the objective to critically analyse andevaluate palaeobotanical and palynological data generated during the period 1950­1990 and to prepare state-of-the-art reports. These reports may help in designingfuture plans of research at the Institute.6

BSlPin Proterozoic succession of Cuddapah, KaJadgiand Bhima basinsSerial sectioning of stromatolites and thin sectioning of associated chert fromCuddapah Basin was completed. Preliminary identification of stromatolitemorphotypes - morpho generic and morphospecific - based on three dimensionalreconstruction revealed the presence of Conophyton, Stratifera undosa, Gymnosolen,Stratifera undata, Kussiella, Jacutophyton, Tungussia, etc. Most of theseforms are characteristic of Early to Middle Riphean age. Thin section study ofassociated cherts revealed low diversity of microbial assemblage, which is mainlydominated by unicellular coccoides with still low frequency of filamentous hollowsheaths comparable to Eomycetopsis sp. It has also been noted that most ofstromatolites are silicified which is a secondary phenomenon. Microstructures aretypical tussocky in nature. Digitate stromatolites show varied types of microstructuresfrom filamentous to rugged nature indicating the role of coccoid and filamentouscyanobacteria in development of the respective microstructure.Samples of Kaladgi stromatolites were also sectioned. The silicified stromatolitesare mostly digitate in nature and may be termed microstromatolites. Theirmicrostructure studies indicate that they were mainly formed by filamentousforms.PROJECT 2Manoj Shukla and Mukund Sharma,GONDWANA COAL AND ASSOCIATEDSEDMENTS : GENESIS, FLORAL EVOLUTIONAND BIOSTRATIGRAPHYProgramme 2.t : Morphotaxonomy, floristics, evolution and strati·graphic significance of plant fossils in KoelValley and Jharia CoalfieldsObjective, To collect plant fossils from different localities: To study morphotaxonomy, evolution, stratigraphicaldistribution of the flora and its significance, To decipher ecological and climatological regimesInvestigation of plant fossils from Datum fireclay quarry of Auranga Coalfieldwas carried out. The assemblage is represented by species of Glossopteris,Noeggerathiopsis, Neomariopteris, Psygmophyllum, Ginkgoites and Saportaea. Theginkgopsid and glossopterid association in the nora suggests similarity with theginkgopsid rich assemblage of the Lower Permian sediments of Rajmahal Hills,Bihar. Plant fossils of Daltonganj and Hutar coalfiel\ls available in the museumwere studied. The fossils are represented by species of Gangamopteris,Glossopteris, Noeggerathiopsis and Vertebraria.

The fossil assemblage mainly consists of leaf impressions,carbonised woods, seeds, fruits, pollen and spores representing all majorplant groups.The palaeobotanical evidences suggest existence of a lowland mixed mesophytieforest communities of broad leaved semi- evergreen to evergreen trees. Anincrease in the "deciduous elements is also noticed. A fresh water swampy environmentof deposition is interpreted for the older horizons due to the presence ofalgal and other aquatic plants, viz., Azolla, Cera/opteris, Typha, Nymphea, etc.Gradually swampy conditions seem to have changed to a bottomland habitat whichis depicted by the presence of a number of ferns and other herbaceous clements inthe subsequent younger horizons.S.

RaoCritical morphotaxonomic evaluation of selected porate pollen grains, viz.,Cryptopolyporites, Varispinitriporites, Thymelaepollis, Rarispinitriporites, Semitecto/riporf/es,Myricipites, and Polyporina was carried out.SamirSarkarMore than 400 gencra and 1000 species of angiosperm pollen have beendescribed from the Tertiary sediments of India. A large number of these taxa havebeen proposed and described on the basis of one or few specimens and meagremorphological differentiation based on insignificant criteria. Thus their usefulnessis limited. The holotypes, para types and other specimens available at therepository of the Birbal Sahni Institute of Palaeobotany, have been restudied,critically evaluated and their morphological limits circumscribed to make themmore useful and applicable for age determination and stratigraphic correlation aswell as for palaeoenvironmental interpretations with emphasis on their affinitywith extant taxa.B.S.

The study has revealed the dominanceof non-arboreals over arboreals. The sparse arboreal vegetation mainly consists ofQuercus followed by Alnus, Betula, Salix and Rhododendron. The herbaceous vegetationis dominated by grasses. Cheno/Ams, sedges, Asteraceae, etc. are alsoprominent constituents.Pollen analytical investigation of a 1.5 meter deep profile from Jore·Pokhari,Darjeeling has depicted equal representation of arboreals as well as non-arboreals.The good representation of Quercus followed by Corylus, Betula, Alnus, Rhododendron,etc. indicates the presence of mixed Oak forest in the region. Grasses togetherwith sedges, Asteraceae, Cheno/Ams, Caryophyllaceae and Ranunculaceaearc the chief representatives of non-arboreal vegetation. Fern spores are in abundancethroughout the sequence.Pollen analysis of 18 samples from BMT/GJR-Il Quaternary Section, Bilaspurhas revealed the dominance of non-arboreals over arborcals. Arboreals are few andscantily represen ted by Quercus, Alnus, Betula, Celtis, Ulmus, etc. The non-arborealvegetation is characterised by the frequent OCCUrrence of Poaceae, Cyperaceae,Ranunculaceae, Polygonum and Asteraceae.Chhaya Sharma, M.S.

1991-92Work other than ProgrammesOrganic petrology and spontaneous combustion susceptibility of coals / lignitesLiptinite macerals in the coals, generally masked by the mineral (inorganic)matter, are most significant in relation to the economical and depositional aspectsof the Permian coals. Under blue light excitation, these macerals (up to 57 %) inSingrauli coals show manifold increase. Also made first authentic record ofBotryococcus algae (alginite) from the coals. A paper on these features has beenpresented at the Palaeobotanical Conference, Lucknow.A scheme for indexing spontaneous combustion susceptibility of Indian coalsand lignites has been proposed, which incorporates most of physical, chemical andpetrological factors recognized to have induced spontaneous heating process. It isalso realized that these factors have only relative significance in their complexinter-relationships, not presently understood, and there may be some other potentfactors not identified, as yet, in Indian conditions.B.K. Misra and B.D. SinghThe coal fire data and its various implications have been studied from India,Canada, Germany, Netherlands and western U.S.A. It has shown that this problemis more prevalent in most of the coalfields having low rank coals in the world. Thevarious facets of this problem particularly the role of resin material and fluorescingvitrinite, besides other factors were dealt in a keynote address' Coal fire - a globalchallenging frontier " delivered at XII International Congress on Carboniferousand Permian Stratigraphy and Geology (ICCP), Buenos Aires, Argentina. Manuscripthas been finalized and submitted for publication.A biopetrological study of some resin samples from U.S.A. is being carried out.It has indicated that the kauri resin is more brittle in nature as compared to theresinous material of Eocene age. The fluorimetric study is in progress.RakeshSaxenaMorphological evolution of pteridophytic spores in relation to aquatic environmentwas analysed. It was observed that the aquatic ferns are mostlyheterosporus with trilete mark. They evolved in Lower Cretaceous and exceptAzolla and Salvinia all of them became extinc~ in Late Maastrichtian. The commongenera are: Arecellites, Molaspora, Balmeisporites, Ariadnaesporites, Glomerisporites,Parazolla, Azolloposis, Azolla and Salvinia. The morphological evolution andadaptation of these genera in relation to aquatic environment is discussed.Studied the pollen morphology (L.M. and SEM) of coryphoid palm genusLicuala Wurmb (9 species) and its phylogenetic relationship with other palmgenera.R.K.Kar55

BSIPStudied the pollen morphology (SEM only) of Pseudophoenix -P. ekmanii, P.sargentii and P. vinifer.Studied the pollen morphology and aperture evolution in Agave Linn.(Agavaceae). It is observed that the transition of developmental stages in aperture,e.g., monosulcate, bisculate, pont-operculate and anazonosulculate are exhibitedby this single genus.K. Ambwani and Madhav Kumar0, e meter deep sediments from Kathuta Thl, ranging in age between ca 200·400 years B.P., were pollen analysed. The study has exhibited good pollen assemblagealbeit non-arboreals predominated. The arboreal taxa encountered fromsedimcnls are Holoptelea, Acacia, Capparis, Combrctaceac, Myrtaccac, Malvaceac,etc. and their collective frequencies range between 3-15 per cent of the totalassemblage. The ground vegetation is largely dominated by grasses and followedby Chenopodiaceae, Asteraceae, Afteman/hera, etc. Polygonum plebejum,Eriocaulon, Cyperaceae, Apiaceae, etc. inhabited the marshy!and along the lakemargins and Lemna, Po/amoge/on, Eichomia, Nymphoea, Nymphoides, etc. inhabitedthe lake water. The study has revealed that tree-less conditions prevailedaround the lake and crop cultivation was on its peak. The lake had wider spread inthe past which was congenial for aquatic and marshy life.M.S. Chauhan, Asha Khandelwal, S.K. Bera and H.P. GuptaThe study reveals high pollen production in Shorea robus/a whereas low percentageof sa! pollen is recorded in surface soils within the forest and graduallydeclines across the open land.Yellow spots colle.;ted from plant leaves in Vikas Nagar, Lucknow duringFebruary, 1992 were pollen ana lysed and found more or less similar pollen compositionas during the previous year. However, several additional taxa belonging toApiaceae and Asteraceae were reported.S.K.BeraAsha Khandelwal and H.P. GuptaOne meter core from Andman Island has been palynologically investigated.Pollen, spores, diatoms and dinoflagellate cysts have been recorded.H.P. Gupta and Asha KhandelwalSubathu Formation exposed in Koshalia Nala Section of Shim!a lesser Himalayahas been studied. Detailed documentation of Early Eocene taxa including Krrboundary nannofossil species are recorded.S.A. Jafar and O.P. SinghWorked out 35 rock samples of Nupra Shale sequence (Jurassic), Thakkolaarea, Nepal, for dinoflagellate contents, under the "International Earth ScienceExpedition Lost Ocean]] in the Plate Tectonic suture zone between Nepal andTibet"56

1991-92K.P. Jain, Rahul Garg and Khowaja-AteequzzamanA well preserved and datable Palaeocene dinonagellate cyst assemblage isdiscovered from an outcropping carbonaceous shale sequence overlying theDeccan Traps near Nareda, south-western Kutch as well as from Lakhpat subcrop.This is extremely significant as age of the earliest Palaeogene clastic sequence inKutch has generated much controversy in recenl years because existence of Palaeocene- Early Eocene rocks dated earlier on foraminiferal and bivalve evidencehas often been denied based mainly on a "false identification" criteria.RahulGargThe distribution of pteridophytic spores in the Tertiary sediments of India hasbeen critically analysed. One hundred and fifty fossil spore genera have beenstudied to understand their morphological range of variation. They have beencompared with the spores of extant taxa. A range chart of pteridophytic sporesincorporating data from the Tertiary strata of India has been prepared.SamirSarkarPalynological and palaeoecological study of the Kundlu and Nalagarh formationspertaining to Lower Siwalik sediments (Mid- Miocene) exposed in andaround Kundlu has been made. Palynological evidences coupled with plantmegafossil records have been used to reconstruct the history of the vegetation ofthis area. Tho distinct palynoassociations have been identified. PalynoassociationI characterises the entire Kundlu Formation which extends into the lower part ofthe younger Nalagarh Formation. It exhibits the excl usive presence of Cosmarium,Pediastrum along with high incidence of Ceratopteris, Lycopodium and Polypodium.Palynoassociation II is characterised by the presence of Pinus, Podocarpus, Acacia,Dipterocarpus, etc. and is confined to the upper part of Nalagarh Formation.Angiospcrmous pollen register a dominant position in this assemblage whereas thealgal elements sharply decline. The present palynonora augumented by megafossilevidences brings to ligh t a broad leaf type of vegetation conforming to warm humidclimate with tropical to subtropical distribution.Samir Sarkar and H.P. SinghDuring noristic survey of Mahuadanr Valley (Chhechari Valley) which is situatedin Chotanagpur plateau region of south Bihar in Palamau District, someangiospermic plants have been collected from different localities in the area forreference collection. 94 species have been identified. Leaf impressions of eachspecies have been prepared in order to understand the morphology of fossil plantleaves. The vegetation of the area is tropical deciduous type. Sal is the dominantspecies in the forest.The study of sedge nora has long been neglected possibly because of its minutegrass-like appearance and complicated noral morphology. There are some membersin the family Cyperaceae which play major role in soil reclamation andprevention of soil erosion. 96 species belonging to 8 genera of Cyperaceae familyhave been collected from eastern Uttar Pradesh. The area includes the districts ofBahraich, Gonda, Basti, Gorakhpur and Deoria. A key for identification of plant57

1991-92MuseumThe Museum of the Institute was actively engaged in executing multifariousactivities particularly relevant to the Professor Birbal Sahni Birth CentenaryCelebrations. The gallery of the institute was adorned with several mounted photographsof Professor Birbal Sahni and his family members. The photographs alsocover important events of Professor Sahni's life as well as those of the institute.Personal belongings of Professor Sahni, like his music book, address book, loanregister and hand-written biography were suitably displayed in the museum. TheSahni Centenary logo was prominently displayed on the multistorey building of theinstitute.Three paintings depicting the Earliest Biosphere and Deccan IntertrappeanVegetational Scenarios were added to the Museum. Another attractive additionwas of a model of the geological clock (Kal Chakra). Black and white photographsof the palynofloral assemblages were replaced by the co loured ones. The legendswere updated and changed. Inventory (part I) of the "lYpe and Figured specimens/slides(megafossils) was also published.The museum collaborated in organising an exhibition on 'The Past oC theGreen World' with National Council of Science Museum at the Regional ScienceCentre, Lucknow. Various aspects of palaeobotany, arranged thematically, wereprojected through specimens, slides, photographs, paintings, transparencies andvegetational scenarios. Important events of the institute, its frame work of investigationsand work culture were shown with the help of audio-visual system. Theroom of Professor Birbal Sahni was recreated mostly with his personal belongings.So far, exhibition has been visited by about 95,000 persons including representationfrom 140 institutions. Besides, an archive has been established to preserveimportant documents, photographs, films, audio and video-tapes, etc.Exhibitions were also organized at the Wadia Institute of Himalayan Geology,Dehradun, coinciding with the symposium on the Siwalik Basin dedicated toProfessor Sahni's memory, and at the Indian Science Congress, Baroda. Someexhibits were sent to the Department of Geology, Jammu University, Jammu alongwith a set of publications released during the Sahni Centenary Celebrations.Several photographs/specimens were gifted to other institutions who had plannedexhibitions on the life and work of Professor Birbal Sahnl. On the same theme, amobile exhibition has been designed. Several fossil specimens mounted on woodenpedestals or embedded in transparent plastic resin were presented as gifts to theguests/delegates during the Sahni celebrations.The National Science Day was celebrated on February 28, 1991. This day wasobserved as an open house.Delegates from the country and overseas, viz., citizens from Argentina, Australia,Hungary, Holland, Madagascar, China, Japan, Poland, Germany, Italy,France, Sweden, Switzerland, U.K. and U.S.A. visited the Museum.111
