Non-pollen microfossils as indicators of environmental changes in the middle Holocene of the Lagoa Comprida, Parque Nacional da Restinga de Jurubatiba, Rio de Janeiro State, Brazil

ABSTRACT The aim of this work was to identify and describe the morphology of non-pollen microfossils present in the sediments of a core collected near the Lagoa Comprida barrier, Rio de Janeiro State, Brazil. Eight forms of fungi, two types of Chlorococcales algae at the colonial stage, one zygospore of Zygnematales, four of diatoms, one of microforaminifer, two cysts of dinoflagellates, one spicule of Porifera, one spore of bryophyte, and nine spores of ferns and lycophytes were identified. Ecological information on the organisms of origin was given to provide reference material for paleoenvironmental reconstruction along the Holocene in restinga areas.
