What is the conventional archaeological date of Skara Brae (Orkney, Scotland), and what alternative dates have been proposed?

Conventional date: Bayliss and colleagues say the first village was founded in the centuries around 2900 cal BC. It may have been left after a fairly short time, then lived in again in the twenty-eighth century cal BC. Alternative proposals: Open question: Why was it left? Bayliss and colleagues say the first village may have been left after a short time, before people came back. The cause is not known. Interpretation: Bayliss and colleagues (2017), a tentative idea: Too much strain? The authors suggest that local tensions may have made close-packed villages hard to keep going across Orkney. They offer this as a provisional idea for the islands, not a finding about Skara Brae. Note on dates: Not the same date: The 2019 sheep study gives about 3500 cal BC. That is when farming animals reached Orkney, not when Skara Brae was built.

What has been measured at Skara Brae (Orkney, Scotland) in peer-reviewed studies?

Part of a World Heritage group: UNESCO lists Skara Brae with the Ring of Brodgar, the Stones of Stenness and the tomb of Maeshowe. Together they make up the Heart of Neolithic Orkney. Orkney lies about 15 km north of Scotland. Stone houses: UNESCO says Skara Brae has houses built of stone. Narrow passages with roofs link them. Site-specific dates: Bayliss and colleagues say the first village was founded in the centuries around 2900 cal BC. It may have been left after a fairly short time, then lived in again in the twenty-eighth century cal BC. An early test case: The same paper says 14 radiocarbon dates from Skara Brae were among the first used in a new kind of statistical dating model (Bayesian). It mixes lab dates with what diggers know about the layers. Sheep that ate seaweed: A 2019 study tested chemical traces in animal bones from Skara Brae. It found sheep ate a fair amount of seaweed from the time they first reached Orkney. Skara Brae is a Stone Age village on Orkney, off the north coast of Scotland. Its stone houses still stand, linked by roofed passages. Scholars agree on its rough age. Why its first village was left so soon is still open.
