MORPHOLOGICAL ANALYSES AND ECOLOGICAL INFERENCES OF POLLEN GRAINS AND SPORES (LAST ~8.000 YEARS) OF THE FERRADURA LAGOON, ARMAÇÃO DOS BÚZIOS, RJ, BRAZIL. This work presents descriptions of spores and pollen grains taken from a Holocene sediment core (22º48'45"S, 41º54'13"W) collected in the Ferradura Lagoon, Armação dos Búzios peninsula, Rio de Janeiro State, Brazil, during the last 8,060-7,770 14 C cal. years BP. The chemical treatment of the sediments and palynological analyses made possible to identify, based on morphological criteria, 119 pollinic types. These types corresponded two families and two genera of bryophyte, six families and seven genera of pteridophyte, one genus of gymnosperm pollen (Podocarpus) and 107 types of angiosperms pollen that consisted of seven families and five genus of monocotyledoneae and 47 families and 66 genus of dicotyledoneae. The most common angiosperm types were: Fabaceae (20), Euphorbiaceae (7), Anacardiaceae (5), Malvaceae (5), Bignoniaceae (4), Sapindaceae (3),
