Widely distributed in central, western and southern regions of India; grown in deciduous and evergreen forests of central, western and southern regions of India. The record of this marine inundation is preserved in the landward extension of the offshore basin since a major part of it was subsiding. Preservation of fossil wood and sub fossil logs is directly related to the sediments in which they are found. Archived from the original on 21 May Vembanad Kottayam Wood 1.

Packing cases and boxes; match splints [45]. The occurrence of subfossil logs and carbonized woods in the sediments associated with the wetlands and river bank deposits, demonstrates clearly that the forest vegetation succumbed almost entirely to the coastal dynamics of the Early Holocene 9—7. Port-related activity is low mainly due to the underdevelopment of ports. Most of the genera occur in forest under storey where their fruits, leaves etc. College for Women, Our History”.

The studied wood samples have yielded ages that fall mainly into two groups. Subsequently it would have risen further by 2—4 m until about yrs BP, and then receded to the present level.

The combination of all these characters indicates that the fossil belongs to genus Dipterocarpus Gaertn. Besides acting as a carbon sink, the wetlands can also serve as a source of carbon, in that they may supply significant amounts of carbon to adjacent coastal ecosystems. Such evidence indicates that these fossils did not drift too far from their place of origin, and hence are of considerable significance in determining vegetation characteristics in the catchments.

Grows well in full sun in clay, loam, sandy, and acidic soil types, with a high drought and aerosol salt wind-borne salt as found in coastal area resistance.

Cambridge University Press, Cambridge. In India, the fossil history of genus Dipterocarpus traces back to Lower Miocene, and a large number of fossils of different plant parts are recorded from different Neogene exposures. This is particularly seen in the seasonal wetlands peripheral to the two main lagoonal water bodies namely thseis Vembanad and Kayamkulam lagoons [60][64]. This article is about the city.
