Thessaloniki, Greece ? Greek researchers have discovered a well-preserved skull of the 5-million-year-old primate. The monkey-like animal was a little more than 3 feet long and had a tail.

Scientists found the skull in the northern Halkidiki peninsula, outside the city of Thessaloniki.

“It’s an important find because it’s in such good condition,” Evangelia Tsoukala, a professor of geology at Thessaloniki University who is heading the excavation, told state-run NET television.
