COPENHAGEN, DENMARK—A Neolithic ax still attached to its wooden handle has been discovered on the Danish island of Lolland. Archaeologists working ahead of the construction of a tunnel unearthed the artifact, which seems to have been ritually deposited on the seabed about 5,500 years ago. "Finding a hafted [handle-bearing] ax as well preserved as this one is quite amazing," Museum of Lolland-Falster archaeologist Soren Anker Sorensen told the BBC. Earlier this year, archaeologists on the project discovered footprints dating to the same period. To read about that discovery, see “Tunnel Reveals Stone Age Footprints.”
