Upper Valdarno is the name given to that part of the Arno valley situated in the provinces of Florence and Arezzo, Italy.
The region is bounded by the Pratomagno mountain range to the north and east and by the Chianti mountains to the south and west.
The Upper Valdarno Basin has provided the remains of three fossil canid species dated to the Late Villafranchian era of Europe 1.9-1.8 million years ago that arrived with a faunal turnover around that time (Early Pleistocene).
It is here that the Swiss paleontologist Charles Immanuel Forsyth Major discovered Falconer's wolf (Canis falconeri) (Forsyth Major 1877).
The species was later reassigned as Canis (Xenocyon) falconeri, but was later regarded as the European arrival of Canis (Xenocyon) antonii.
The species gave rise to Canis (Xenocyon) lycanoides.
