1996-97 - Birbal Sahni Institute of Palaeobotany

1996·97
Fifteen genera belonging to fungi, pteridophytes, gymnosperms and angiosperms have
been identified. The generated data base is not sufficient for any tangible interpretation.
Visited Kalakot, Uttarbaini and Jammu areas of Jammu and Kashmir.
Stratigraphically located samples from Subathu Formation as well as Siwalik Group
of rocks were collected. Reconnaissance survey was also made at several places of
Jammu as well as Himachal Pradesh and Haryana.

climate

Leaf-impressions collected from Kasauli, Dagshai and Dharmshala were studied.
Leaveslleaflets belong to Amoora, Bambusa, Bauhinia, Dipterocarpus, Ficus, palmate
palm and legumes.

The work on plant megafossils from Siwalik sediments of Surai Khola, Nepal
was completed and submitted for publication. Its palaeoecological and
phytogeographical implications have been discussed.

The leaf-impressions, collected from Arjunkhola, Koilabas, Seria Naka,
Tanakpur and Hardwar were investigated. The assemblage reveals the presence of about
35 new taxa. Out of which, 9 taxa are from Arjunkhola (Securidaca inappendiculata,
Dipterocarpus bourdillonii, D. incans, Anisoptera scaphula, /soptera bomiellsis,
Drim.ycarpus racemosus, Flemillgia wightiana. Sapindus al1elluotus, TerminGLio
tomelltosa), II from Seria Naka (Fissistigma wallichii, Mitrephora macrophylla,
Phaeallthus sp., GOlliothalamus sp., Flacourtia cala/racta, Mallgi/era illdica,
Dracontomelon sylvestre, Dalbergia volubilis, Nephelium glabrum, Diospyros pruriens,
Diospyros sp.), 10 from Koilabas (Brucea mollis, Shorea trapizi/olia, Miliusa thoretii,
Fissistigma elegans, Popowia nitida, Berchemia rhamosa, Dalbergia cultrata,
Cynometra eripa, Phyllanthus reticulatus, P columllaris), 3 from Hardwar (Vatica
mallgachapoi, Eugellia occidelltalis, Bassia longi/olia) and 2 from Tanakpur
(Mitrephora maillgayi, Oxymitra biglandulosa).
Fossil woods collected from Siwalik sediments of Kalagarh and Tanakpur have
been cut and studied. Most of them are found duplicate resembling Hopea, Shorea,
Dipterocarpus, Bauhinia, Millettia and Diospyros, besides 3 new taxa which are under
