The team has reached sockets that once held bluestones - smaller stones, most now missing or uprooted, which formed the site's original structure. The researchers believe that the bluestones could reveal that Stonehenge was once a place of healing.
The dig is the first to take place at Stonehenge for more than 40 years. The team now needs to extract organic material from these holes to date when the stones first arrived.
Swedish archaeologists have discovered a rare hoard of Viking-age silver Arab coins near Stockholm's Arlanda airport.
About 470 coins were found on 1 April at an early Iron Age burial site. They date from the 7th to 9th Century, when Viking traders travelled widely.
There has been no similar find in that part of Sweden since the 1880s.
Most of the coins were minted in Baghdad and Damascus, but some came from Persia and North Africa, said archaeologist Karin Beckman-Thoor.
