Early Cretaceous The multituberculate fossil assemblage from Galve comprises at least four taxa: the paulchoffatiid Gal- Multituberculata Galve veodon nannothus, the eobaatarid Eobaatar hispanicus, another eobaatarid or a possible plagiaulacid, Iberian Peninsula Iberica hahni gen. et sp. nov., and the pinheirodontid Lavocatia alfambrensis. The species Parendotherium Systematic Review herreroi has been removed from the multituberculate faunal list of Galve. Another two different taxa, Iberica hahni gen. et sp. nov provisionally classified as Paulchoffatiidae indet. and Plagiaulacidae or Eobaataridae indet. could be added to the list if their validity can be assessed once more specimen are found. The presence of more than four different “plagiaulacidan” multituberculate taxa in the late Hauterivianeearly Barremian of the Galve area suggests a high biodiversity of these mammal faunas in the Early Cretaceous age of the Iberian Peninsula.

Introduction “plagiaulacidan” multituberculates constitute the most abundant and diverse remains in the mammal fossil assemblages, although other The village of Galve (Central Iberian Range), province of Teruel taxa have also been found, such as “eupantotherian” (dryolestoid, (northeastern Spain), and its surroundings are becoming one of the peramurid) and “symmetrodontan” (spalacotheriid) mammals most important areas of the Iberian Peninsula in the study of Early (Krebs, 1993; Canudo and Cuenca, 1996; Hahn and Hahn, 2002; Cretaceous vertebrate faunas.
