Systematic paleologic research and excavations have been carried out for the last 17 years by the Aristotle University of Thessaloniki in the region of Grevena. In 1997 the excavation team discovered the first pair of impressively sized tusks (4.39 m. long), the biggest ones belonging to that particular species to be found in Greece, Europe and possibly the world. In 2007, the second discovery of yet another fossilized animal highlighted the importance of the area near the village of Milia. Its geological age is estimated at 1.5 - 3 million years! The region has been a battlefield in the 40’s for the violent clashes of the Mussolini’s Italian army against Greece.
