Amphilagus plicadentis (Lagomorpha, Mammalia) from the Tagay locality (Olkhon Island, Baikal region, Eastern Siberia)

New excavations in the Tagay locality have revealed the presence of Amphilagus plicadentis Erbajeva, 2013 , which belongs to the palaeolagine Lagomorpha rather than leporids, previously referred to Procaprolagus sp. (Logachev et al., 1964 ). Herein, we report a comprehensive morphological descriptio...

Description
Summary:New excavations in the Tagay locality have revealed the presence of Amphilagus plicadentis Erbajeva, 2013 , which belongs to the palaeolagine Lagomorpha rather than leporids, previously referred to Procaprolagus sp. (Logachev et al., 1964 ). Herein, we report a comprehensive morphological description of this species and compare it with the other known species of the genus Amphilagus . The Tagay lagomorph is conspecific with the Early Miocene species Amphilagus plicadentis found at locality Unkheltseg (UNCH-A) (biozone D; Early Miocene) in the Valley of Lakes, Central Mongolia. The Tagay specimens suggest a more advanced evolutionary stage of A. plicadentis and an age around Early/Middle Miocene transition.
