The Kiputz IX site has provided one of the best-preserved late Pleistocene bison populations in the southern Pyrenees and has yielded the first almost complete skull of a steppe bison (Bison priscus) in the Iberian Peninsula. This Bison priscus skull is compared on morphological and osteometric grounds with other specimens of steppe bison from Europe and North America. The skull from Kiputz IX falls within the range of the extinct subspecies Bison priscus mediator. Available data support the evidence of three chronological subspecies of Bison priscus (Bison priscus gigas, Bison priscus priscus, and Bison priscus mediator) during the Middle and late Pleistocene. Resumen. PRIMER CRÁNEO COMPLETO DE BISONTE ESTEPARIO (BISON PRISCUS) EN EL PLEISTOCENO TARDÍO DE LA PENÍNSULA IBÉRICA. El yacimiento de Kiputz IX ha proporcionado una de las colecciones de bisonte mejor preservadas al sur de los Pirineos durante el Pleistoceno tardío, además de aportar el primer cráneo completo de bisonte estepario (Bison priscus) encontrado en la Península Ibérica. Este trabajo presenta los resultados del estudio morfológico y osteométrico del cráneo de Bison priscus y compara las medidas con otros ejemplares de bisonte estepario de Europa y América del Norte. El cráneo de Kiputz IX ha dado valores cercanos a los de la subespecie extinguida Bison priscus mediator y proporciona datos que respaldan la evidencia de cronologías de tres subespecies sucesivas de Bison priscus (Bison priscus gigas, Bison priscus priscus y Bison priscus mediator) durante el Pleistoceno medio y tardío.Downloads
