What is "vetulonia"

Vetulonia, formerly called Vetulonium ( Etruscan Vatluna), was an ancient town of Etruria, Italy, the site of which is probably occupied by the modern village of Vetulonia, which up to 1887 bore the name of Colonnata and Colonna di Buriano: the site is currently a frazione of the comune of Castiglione della Pescaia, with some 400 inhabitants.

It lies 300m above sea level, about ten miles directly northwest of Grosseto, on the northeast side of the hills which project from the flat Maremma and form the promontory of Castiglione.

Vetulonia is a genus of sea snails, marine gastropod mollusks, unassigned in the superfamily Seguenzioidea.
