A team of Greek paleontologists have discovered the tusks and fossilized remains of a 3-million-year-old mammoth-like mammal in Grevena, northern Greece. The tusks of the mastodon weigh a ton each and are 5 meters in length, the longest ever found. The mammal, believed to have been a male aged around 25, was 3.5 meters tall and weighed over 6 tons, according to experts. «This is a rare and unique find for Greece and is useful for studies of the period,» said Evangelia Tsoukala, the head of a team of Greek and Dutch experts who has been working in the Grevena region for the past 10 years. Tsoukala's team also uncovered thigh bones and teeth believed to have belonged to the same animal. In 1998, the same team discovered another pair of mastodon tusks, measuring 4.38 meters.
