Marine reptiles from Late Cretaceous (early Maastrichtian) deposits in Algarrobo, central Chile

► We report new marine reptiles of early Maastrichtian age from central Chile. ► This record adds an emerging picture of the marine reptile faunas of the Weddellian Biogeographic Province during the latest Cretaceous, shedding light on the vertebrate diversity in the northern limits of this Province. ► The tentative presence of cf. Dermochelyidae may reaffirm a connection between Weddellian and North Pacific marine reptile assemblages since Campanian time.
