Cueva Victoria has provided remains of more than 90 species of fossil vertebrates, including
a hominin phalanx, and the only specimens of the African cercopithecid Theropithecus
oswaldi in Europe. To constrain the age of the vertebrate remains we used paleomagnetism,
vertebrate biostratigraphy and 230 Th/U dating. Normal polarity was identified in the non-
fossiliferous lowest and highest stratigraphic units (red clay and capping flowstones) while
reverse polarity was found in the intermediate stratigraphic unit (fossiliferous breccia). A …
