Officials say the vast ancient burial mound at Amphipolis in Greece could contain more than one dead.

Greek Culture Minister Costas Tasoulas said Saturday scientists have started the second phase of excavation at the burial site, dating back to Alexander the Great's reign in the late 4th century B.C. He said scientists are searching for possible additional burial chambers below the splendid, three-chamber tomb discovered in August.

He said there is still a long way to go to examine the findings from the first phase of the excavation. Anthropologists will try to identify the skeleton's gender and age, but warn the full identity might never be known.

Meanwhile archaeologists are still uncovering the multicolored decorations found inside the tomb. Both projects are expected to take several months.
