A prehistoric stone panel said to be the "most important in Europe" is being unearthed for the first time in more than 50 years in Clydebank.
The Cochno Stone dates to 3000BC and is described as one of the best examples of Neolithic or Bronze Age cup and ring markings in Europe.
Located next to a housing estate, the stone was buried in 1965 to protect it from damage.
Excavation work started on Monday and is expected to last three weeks.
Archaeologists will use 3D-imaging technology to make a detailed digital record of the site.
They hope this will provide more information on the stone's history, purpose and the people who created it about 5,000 years ago.
