Abstract Classifying fossil teeth of Erinaceinae (spiny hedgehogs) is a challenging task, because of their scanty record and systematic treatment that heavily relies on skull characteristics. In this paper we describe the complete set of isolated dental elements of Erinaceinae from the upper Miocene sediments of the Teruel Basin (eastern Central Spain). Four different species were recognized: Postpalerinaceus cf. vireti, Atelerix aff. depereti, Atelerix steensmai nov. sp., and a form classified as Erinaceinae genus and species indet. All four are relatively derived in showing multi-purpose dentitions, not showing only adaptations to insectivory, but also to carnivory, herbivory and possibly durophagy/malacophagy. The temporal occurrence of spiny hedgehogs during the middle to late Miocene in the Teruel Basin and neighboring Calatayud-Montalban Basin peaks within periods of relative aridity, a correlation consistent with modern geographic distribution. Messinian cooling is the best candidate for explaining a remarkable demise of Erinaceinae at 7 Ma.

来自特鲁埃尔盆地（西班牙）的晚中新世 Erinaceinae

摘要 对刺猬亚科（刺猬）的牙齿化石进行分类是一项具有挑战性的任务，因为它们的记录很少，而且系统处理严重依赖于头骨特征。在本文中，我们描述了来自特鲁埃尔盆地（西班牙中东部）的上中新世沉积物的完整的一组独立的刺猬亚科牙齿元素。识别出四种不同的物种： Postpalerinaceus cf. vireti，Atelerix aff。德佩雷蒂，Atelerix steensmai 11 月 sp.，以及归类为 Erinaceinae 属和种 indet 的一种形式。所有四种都相对衍生出多用途牙列，不仅表现出对食虫的适应，而且还表现出对食肉、食草和可能的硬食性/恶食性的适应。特鲁埃尔盆地和邻近的卡拉塔尤德-蒙塔尔班盆地在中新世中晚期刺猬的时间出现在相对干旱时期达到顶峰，这种相关性与现代地理分布一致。墨西拿冷却是解释 7 Ma 时Erinaceinae 显着死亡的最佳候选者。
