The remains of a prehistoric mastodon - a mammoth-like animal - have been found in northern Greece, including intact long tusks.
The mastodon's tusks measure 5m (16.5ft) and 4m. They are the longest tusks ever found on a prehistoric elephant-like animal.
The animals were similar to woolly mammoths, but had tusks that pointed forwards, rather than spiralling upwards. Their teeth were also different.
