Couldn't they be weights for frame looms or fishing nets etc? The carved ones I mean.
Anyway today's Grauniad has added a new stone circle to the Dartmoor collection.
'The highest stone circle in southern England has been found on a weather-battered slice of moorland in Devon.
Situated 525 metres (1,722ft) above sea level, the ancient site is the first stone circle to be found on Dartmoor for more than a century.
The circle is the second largest on the moor and archaeologists believe it was probably part of a “sacred arc” of circles around the north-eastern edge.

First stone circle for over a century is discovered on Dartmoor - THE first stone circle for more than a... http://t.co/jfly9uGiq6
Its discovery adds weight to the theory that there was some kind of planning and liaison between the communities living on Dartmoor in the late Neolithic/early Bronze Age 4,000 to 5,000 years ago.'
'With a diameter of 34 metres (112ft), the circle consists of 30 recumbent stones, plus one more lying in a gap just outside the circle and now incorporated into an unfinished enclosure wall.
The stones probably came from the nearby Sittaford Tor itself and are of a fairly uniform size, suggesting they were carefully chosen. Packing stones visible around the bases of some of these indicate that they were originally upright.
When upright the circle would have been very impressive, dominating the surrounding landscape and resembling in appearance the Grey Wethers double stone circle, which lies close to Fernworthy forest about half a mile away.'http://www.theguardian.com/science/2015 ... moor#img-1
