A1 Agustí, J. A1 Parés, J. M. AB The magnetostràtigraphic study of vallesian sites in the Vallès-Penedès Basin (NE Spain) provides a reliable dating of the earliest appearance of Hipparion at 11.1 Ma. Good agreement with radiometric ages from other sites in Central Europe and Turkey suggests an isochronous dispersal o f this eq uid throughout the Mediterranean region. A possible isochrony at a larger geographical scale (Eurasia and Mesogea) is not ruled out, but must await more reliable ages of other Hipparion first appearance records in Asia and Africa PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/12820 UL http://hdl.handle.net/10272/12820 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 19 jun 2026
