Materials from the localities of Araia d'Alcora in the Ribesalbes-Alcora Basin (Spain, early Miocene, Biozone C, MN4) have yielded an assemblage of erinaceids and metatherians, relatively rich for an Iberian site. The most common erinaceid is the gymnure Galerix symeonidisi Doukas, 1986, present in almost all of the studied sites. Other erinaceids in the faunal list are possibly an indeterminate species of the genera Lantanotherium Filhol, 1888 and Atelerix Pomel, 1848, in what constitutes one of their oldest occurrences in Europe. Metatherians are represented by the herpetotheriid Amphiperatherium frequens erkertshofense (Koenigswald, 1970). The material described here was partially published by Furió and colleagues in 2012. We complete it with new material from the known localities and with material from new sites. We describe for the first time the lower dentition of this taxon in this basin, thus increasing knowledge of the high variability of its decidual molars. In addition, the climatic preferences of the species A. frequens (von Meyer, 1846), which was probably less strict in its humidity requirements than previously thought, are also discussed.

来自 Ribesalbes-Alcora 盆地（西班牙）的早中新世有袋动物、裸鼠和刺猬

来自 Ribesalbes-Alcora 盆地（西班牙，早中新世，Biozone C，MN4）的 Araia d'Alcora 地区的材料已经产生了一个组合的 erinaceids 和 metatherians，对于伊比利亚遗址来说相对丰富。最常见的erinaceid是gymnure番石榴Doukas, 1986，几乎所有的研究地点都有。动物区系列表中的其他 erinaceids 可能是该属的不确定物种镧属菲尔霍尔，1888 年和阿泰莱克斯Pomel，1848 年，这是他们在欧洲最古老的事件之一。Metatherians由herpetotheriid代表两栖动物 erkertshofense（柯尼希斯瓦尔德，1970 年）。此处描述的材料部分由 Furió 及其同事于 2012 年出版。我们使用来自已知地区的新材料和来自新站点的材料来完成它。我们首次描述了该盆地中该分类单元的下齿列，从而增加了对其乳磨牙高变异性的认识。此外，物种的气候偏好A. 频率(von Meyer, 1846)，它的湿度要求可能没有以前想象的那么严格，也被讨论了。
