“…The presence of these species in the T_D core suggests an environment more strongly influenced by the marine environment (Ekdale 1974). In the coastal region of Espírito Santo State, these species of benthic organisms have been reported in sandy and sandy mud sediments (Castro and Santos 1989), corroborating the data in our study. According to Le Roux and Rojas (2007), both the degree of selection and the diameter of the sediment grains provide important indicators for palaeoenvironmental characterization of past environments, supplying information on the energy in the environment, and the distance and duration taken for the sediment to be transported (e.g.…”

Dinocysts as a Tool for Palaeoenvironmental Reconstruction in Vitória Bay, Brazil

et al. 2020

Micropaleontological and geochemical data were applied to sediments from southeastern Brazil to study the hydrodynamics associated with the Holocene sea level rise. Sediment cores were taken around Vitória Bay, examined for dinoflagellate cysts and subjected to isotopic analysis. The cyst assemblage mainly dominated by autotrophic species most notably O. centrocarpum, L. machaerophorum and T. vancampoae. The influence of the marine transgression and subsequent regression observed during the Holocene along the coast of Brazil could have initially favored the establishment of an oligotrophic and higher energy environment. The inflow of continental water from tributaries combined with a higher inflow of saline water into the estuarine system could have favored the establishment and subsequent deposition of the dinocysts.
