Villafranchian

Villafranchian age (

European Land Mammal Ages. Named by Italian geologist Lorenzo Pareto[3] for a sequence of terrestrial sediments studied near Villafranca d'Asti, a town near Turin,[4] it succeeds the Ruscinian age, and is followed by the Galerian
.

The Villafranchian is sub-divided into six faunal units based on the localities of Triversa, Montopoli, Saint-Vallier, Olivola, Tasso and Farnetta.[2]: 149 

A major division of both geological deposits and time, the Villafranchian is significant because the earliest hominids that clearly evolved into modern man (the

australopithecines) appeared within it.[4] The Villafranchian is partially contemporaneous with the Blancan Stage of North America.[4]

Many animals and their extinct ancestors evolved during the Villafranchian, including the Red fox, Least weasel, Moorhen, Etruscan bear, and Panthera gombaszoegensis.

The beginning of the Villafranchian is typically defined by the first appearance of the bovid genus

Pachycrocuta brevirostris approximately 1.8 mya.[5]
