New data on the Early Villafranchian fauna from Vialette (Haute-Loire, France) based on the collection of the Crozatier Museum (Le Puy-en-Velay, Haute-Loire, France)

Vialette (3.14 Ma), like Seneze, Chilhac, Sainzelles, Ceyssaguet or Soleilhac, is one of the historical sites located in Haute-Loire (France). The lacustrine sediments of Vialette are the result of a dammed lake formed by a basalt flow above Oligocene layers, and show a geological setting typical for this area, where many localities are connected with maar structures that have allowed intra-crateric lacustrine deposits to accumulate. Based on previous studies and this work, a faunal list of 17 species of large mammals has been established. Eight species, typical of this time period and well known, occur in the collection of the Crozatier Museum of Le Puy-en-Velay: Pliocrocuta perrieri, Lynx issiodorensis, Mammut borsoni, Anancus arvernensis, Stephanorhinus jeanvireti, Tapirus arvernensis, 'Cervus' pardinensis and Croizetoceros ramosus. The presence of Gazella cf. G. borbonica is newly established, in addition to which the oldest known occurrences of Canis sp., cf. Eucladoceros sp. and of the genus Equus in Western Europe are also described. These are the new data which pushed back the age of the arrival of the genus Equus, cf. Eucladoceros and Canis in Western Europe. Five taxa are not found in the Crozatier collection: Primates indet., Agriotherium sp., Ursus gr. minimus-thibetanus, Bovidae middle-sized (?Pliotragus ardei or ?Gallogoral meneghinii), ?Procapreolus cf. cusanus.
