Short summary
During the early Toarcian (Jurassic, 180 Ma) a hyperthermal event, the Jenkyns Event, occurred, affecting the oxygenation of the sea bottom. The integrated study of foraminiferal and ostracod assemblages with geochemical proxies allows us to interpret the incidence of this event in the Western Tethys, more exactly in the South Iberian Palaeomargin. Diminution of diversity, changes in abundance, and opportunist vs. specialist are coincident with the event.
