Cut into a triangle from a single piece of shale -like shape, the tiny pendant measures merely 31mm by 35m is an only 3 mm thick.
Archaeologists happen to be painstakingly analyzing a number of lines which decorate the artifact. After close study they say the lines could represent a leaf, a map, a tree or tally marks.
Research workers nearly missed the find, that was discovered in lake border deposits, as they thought it was at first it was nothing greater than the usual rock.
Sediment had obstructed the hole in the pendant. But when the find was first found, at the Early Mesolithic site at Star Carr, North Yorkshire, after a lot of years in the ground, the miniature lines were scarcely observable.
