1,400-year-old tomb found in U.K.

A painted wooden box fragment

An underground chamber discovered by road workers appears to be the site of the earliest Christian royal burial ever found in Britain. Researchers are calling it the Anglo-Saxon equivalent of King Tutankhamun's tomb. The chamber was uncovered between a road and a railway line in the southeastern English village of Prittlewell in 2003.

Archeologists say it is the most important Anglo-Saxon burial discovery in more than 70 years. Treasures unearthed at the site include a golden belt buckle, the remnants of a lyre, and gleaming glassware.

It's thought to be the burial chamber of the brother of Anglo-Saxon King Saebert. Fragments of tooth enamel -- the only human remains uncovered -- revealed the occupant of the rich burial was just over 6 years old.
