MAnE- RESUMEN ABSTRACT En este trabajo se presenta una sintesis de los Suoidea There is a good record of Suoidea (- Suidae + de la Peninsula Ibérica. Tayassuidae; Mammalia, Artiodactyla) from the Miocene Los Suoidea ibérioos están compuestos por treinta of the Iberian península, besides Suidae are siso known especies y subespecies. Para cada taxón se presenta from the IberianPliocene and Pleistocene. una lista de localidades y se presenta una distribución The lberian Suoidea (30 species and subspecies) are temporal. briefly described or reference is made to a recent description. For eacn taxon a Ilst of localities where it is found is presented and a range-cnart has been compiled. The Suoidea of the lberian penlnsula are compared to those of the rest of Europe. Some of the differences are the absence of Taucanamo, Sanitherium and Mlcrostonyx antiquus In Spain and Portugal and the presence or abundance in Spain of SdJizochoerus and Parachleuastochoerus. Further differences are in sorne ranges: Bunolistriodon, K. provincialis and S. arvemensis are known from older localities in Spain than in France; K. provincialis also enters early in ltaly. Species diversity was high during the Eany Aragonian and near the transition from the Aragonian to the Vallesian. Uke in other parts of Europe, speciesdiversity became very Iow alter the Vallesian. K. palaeochoerus is the only species crossing the MN 9 - MN 10 limit for a substantial periodo The cause of this change must be an important ecological event because in Africa and the Indian Subcontinent suoid species diversity remained high. INTRODUCTION lberian Suoidea and to study the changas in the suoid fauna. A last goal is to compare the lberian Suoidea This paper has several goals. One is to give a list to the rest of Europe aoo to study the changas in the of the lberian species and the localities where they Suoid record. In soma cases it was necessary to occur.
