ABSTRACT

The Galericinae are a group of Erinaceidae that are currently distributed in Southeast and Eastern Asia. Although galericines have an Asian origin, their fossil record in this region is scarce, which greatly limits the knowledge of the evolutionary history of this group. We describe here the first fossils of Eulipotyphla from the middle Miocene (13.4–13.2 Ma) of the Mae Moh Basin of northern Thailand, and assign the material to three taxa of Erinaceidae attributable to the Galericinae (Galerix rutlandae, Lantanotherium anthrace, sp. nov., and Lantanotherium sp.). The Mae Moh erinaceids present a Lantanotherium-Galerix association that is uncommon in the Miocene of Asia. Galerix rutlandae is a species formerly described in the Siwaliks of Pakistan and India, which reaffirms the strong affinities during the middle Miocene between the mammalian faunas of Southeast and Southern Asia. The discovery of two species of Lantanotherium in Mae Moh provides additional knowledge about the evolution in Asia of this widespread Miocene genus that had never been recorded in Southeast Asia. The presence of three Galericinae in Mae Moh Basin reinforces the hypothesis of a mainly closed and wet environment during the deposition of the K and Q lignite layers.

摘要

Galericinae是一群Erinaceidae，目前分布在东南亚和东亚。尽管半胱氨酸起源于亚洲，但在该地区的化石记录却很少，这极大地限制了该群体的进化史知识。我们在这里描述了泰国北部Mae Moh盆地中新世中期（13.4-13.2 Ma）的第一类Eulipotyphla化石，并将其归因于Galericinae的Erinaceidae的三个分类群（Galerix rutlandae，Lantanotherium anthrace，sp。nov）。以及Lantanotherium sp。）。Mae Moh erinaceidids呈现出Lantanotherium - Galerix协会，在亚洲中新世罕见。芸香是先前在巴基斯坦和印度的锡瓦利克人中描述的一种物种，它重申了中新世中期东南亚和南亚哺乳动物区系之间的强烈亲和力。在湄茂（Mae Moh）发现了两种Lantanotherium，提供了有关该中新世属在亚洲从未有过记录的亚洲演化的更多知识。湄茂盆地三个Galericinae的存在强化了在K和Q褐煤层沉积过程中主要封闭和潮湿环境的假说。
