This paper examines the role played by palaeoceanographic and climatic conditions on the palaeobiogeography of the
Pliensbachian–Toarcian ostracods (Early Jurassic) in the European Epicontinental Sea (EES). The influence of the
palaeogeography, ocean currents and sea level, temperature and salinity variations on ostracod abundance, diversity and migration
patterns is reconstructed. Ostracod migration follows an anticlockwise circulation in the eastern side of the EES, with a leading
northeast–southwest movement, and the frequent arrival of Tethyan faunas into the central and western parts of the EES during the
Pliensbachian. A three-fold classification of water masses based on salinity, temperature, lithological and fossil data is proposed.
The repeated inflow of Tethyan ostracods into the EES ended by the earliest Toarcian. This ostracod event is related to the opening
of the Hispanic Corridor and to the reorganization of the surface and deep circulations that may have generated a cold episode at the
beginning of the Toarcian.
