This canid is very important because it signals the advent of the so-called wolf-event, that is the modification of the groups of European carnivores which occurred about 2.5-2.4 million years ago following the onset of climatic changes typical of the Quaternary, characterized by fluctuations of temperature and progressive increase of aridity during the colder phases. This involves the arrival in Europe of representatives of the genus Canis: Canis etruscus is in fact the oldest representative of these animals. It reached dimensions comparable to that of a current wolf, it may be that it was a social animal like the latter and therefore that it hunted in packs. Among the favorite prey of the canids of the time are the "false" fallow deer of Nesti and the deer with comb-shaped antlers.
