Scientists have uncovered the remains of two prehistoric men in an Irish bog, one of which is the tallest body from the Iron Age ever found.

Ned Kelly, head of antiquities at the National Museum of Ireland says the 6-foot 6-inch man "would have been a giant...the other man was quite short, about 5 foot 2 inches."

Another surprising discovery made by the scientists is that the shorter man appeared to have used hair gel.

Kelly tells BBC radio, "The shorter man appeared to attempt to give himself greater stature by a rather curious headdress which was a bit like a Mohican-style with the hair gel, which was a resin imported from France."

Named Clonycavan Man, the shorter man's ability to buy imported products suggests he part of wealthy Irish society some 2,300 years ago. The taller man was named Oldcroghan Man.

The peat bogs were able to preserve the remains so well that even fingerprints were visible. Kelly says both men had experienced violent deaths. His head was cut off and his body cut in half.

He adds, "Oldcroghan Man was stabbed through the chest. He saw that attack coming because there is a defensive injury on his arm."

Clonycaven Man head had been split open with an axe before he was disemboweled.
