Short summary
We present a deep systematic and taxonomic revision of the Early Jurassic calcareous nannofossils from the Neuquén Basin. The study focuses on characterizing the assemblages and identifying bioevents. The Pliensbachian associations from the Los Molles Formation are ilustrated for the first time, along with new biostratigraphic data from the area. Similarities found with locaties from the proto-Atlantic region suggest a connection between the Pacific and Tethys oceans during the Early Jurassic.
