This chapter summarizes the abundant marine paleobiological markers recorded in theVaca Muerta Formation illustrating their richness, biodiversity, and application for age datingand paleobiogeographical global correlation. The markers described include ammonites, calcareous nannofossils, calcisphaeres (calcareous dinoflagellate cysts), calpionellids, coprolites,dinoflagellates, radiolarians, saccocomid microcrinoids, and trace fossils. Traditionally,the ammonites have been the best known and most relevant macroinvertebrate fossil group.Nevertheless, in the past decade, the exploration of the Vaca Muerta unconventional play hasboosted the research on the micropaleontology of the area determining an extensive growthin knowledge, reported here
