The main palaeobiological markers recorded in the Vaca Muerta Formation are presented, including ammonites, calcareous nannofossils, calcisphaeres (calcareousdinoflagellate cysts), calpionellids, coprolites, dinoflagellates, radiolarians, saccocomid microcrinoids, and trace fossils. Traditionally, the ammonites were the most well-known and relevant macroinvertebrate fossil group. Nevertheless, in the past few years, thanks to industrial requirements corresponding with the importance of Vaca Muerta as an unconventional reservoir, the micropaleontology of the area has derived extensive growth in its knowledge.
