“…Total of 60 samples were collected at random intervals (20 from each peat layer) for palynological study and six samples (two from each peat layer, from topmost and from bottom of the layers) were collected for 14 C dating. The radiocarbon dating of the collected samples was determined following RAJAGOPALAN et al (1978) at Birbal Sahni Institute of Palaeobotany, Lucknow, India. For palynological study, samples were prepared by standard acetolysis process (FAE- GRI & IVERSEN 1975).…”

Palynological analysis was conducted in view of past ecological reconstruction trends of Calcutta, the Lower Bengal Basin (West Bengal), India. Floristic compositions were derived from peat samples collected from Garia, located at the southern extremity of the city. Garia, being one of the oldest settlements in this region, is situated by the ‘Tolly Nullah’ connecting Calcutta to the Vidhyadhari River at the east. Bore hole samples were radiocarbon dated and three successive peat layers of 7000 (+170) y. B.P. to 2650 (+150) y. B.P. were analyzed for their pollen composition. Pollen data indicates the existance of typical swampy vegetation of mangrove plant community in and around Calcutta, which are presently confined to the Sundarbans forest, the further south of the studied area. The lower most peat layer (ca. 7000–6500 y. B.P.) reveals that the vegetational sequence was comparatively uniform and mainly comprised of Heritiera, Rhizophora, Sonneratia, Excoecaria, Phoenix paludosa and grasses, implying insignificant fluctuations in climatic conditions. The middle layer indicates a mixed vegetational type of fern spores, mangroves and some terrestrial plants (e.g. Acanthus, Cynometra, Suaeda, and grasses). The lower part of the middle peat layer (ca. 6450–6100 y. B.P.) consisted of marshy habitat as evidenced by fern spores, whereas their absence in the upper part implies relatively dry environmental conditions. The upper peat layer (ca. 2600 y. B.P.) is dominated by grass, pollen grains terrestrial habitats (Typha, Cassia, Eucalyptus, Desmodium, Salicornia, and Rhamnaceae) and some of typical mangroves (Heritiera and Excoecaria). Low amounts of fern spores indicating Lower Bengal change towards the terrestrial habitats. The pollen/spore assemblages in the three successive peat layers indicate the presence of typical mangrove vegetation, of the type currently observed in the Sundarbans region. Frequent sea water inundation mixed with fresh water flow from the northern upstream at the low lying topography of Basin seems to have led to the formation of peat by deposition rather than by drifting.

“…Charcoal present in the samples was collected and radiocarbon dated. We have so far 9 14 C dates carried out at BSIP, Lucknow, India (lab code BS-), using liquid scintillation counting (Rajagopalan et al 1978) and 17 accelerator mass spectrometry (AMS) dates of charcoal and grain samples done at Paleo-Labo, Co. Ltd, Japan (Tables 1 and 2). Pretreatment was performed at Paleo-Labo (lab code PLD-) and 14 C concentrations were measured with the Paleo-Labo AMS system (NEC, 1.5SDH).…”

This article presents the results of 4 excavation seasons in which botanical and animal remains were collected at the Harappan site of Kanmer in the Kachchh District of Gujarat, India. The findings revealed a subsistence economy consisting of food production with domesticated plants and animals, hunting, fishing, and wild plant gathering. Cultural relics and radiocarbon dating support our identification of different cultural periods at the site. This study provides new insights into the subsistence strategies during different phases of occupation and offers the potential for new subsistence models to be applied at nearby sites, particularly in this peripheral zone of the Indus civilization.
