The Erinaceidae from the late Oligocene of Coderet-Bransat and Peublanc (Allier, France; MP 30): new data on Amphechinus pomeli (Schlosser, 1925-26) and Galerix minor (Filhol, 1880)

Description

The late Oligocene faunas from central France are often rich and provide crucial information for understanding the evolution of mammals during the Oligocene-Miocene transition. The locality of Coderet-Bransat, where Amphechinus arvernensis was so far the only known hedgehog, yielded new specimens hitherto identified as Galerix minor and Amphechinus pomeli. The new specimen of Amphechinus pomeli, together with a new study of the type specimens from Peublanc, confirm the previously questioned validity of this species, the smallest of all hedgehogs. The similarities between the faunal lists of Coderet-Bransat and Peublanc indicate a very close age (MP30), whereas some aquatic taxa only found in Peublanc suggest a slightly different palaeoenvironmental context compared to Coderet-Bransat.
