| Title |
Probable Drilled Stone Bead |
||
| Description |
English: An oval shaped stone with a flattened base, that has a roughly circular perforation through the centre. The perforation is set at 90 degrees from the flattened base and has a diameter of 4.68mm. The stone weighs 3.68g, has an oval diameter of 17.63mm x 14.46mm and height of 13.94mm.
Discussion: Stones can have naturally occurring cylindrical perforations if the stone has formed around another item such as Belamite fossils. The stone can then be eroded and weathered into pebbles that fortuitously resemble beads and therefore makes identification difficult. Dr Kevin Leahy identifies this find type as the remains of fossilised sponges. These small perforated sponges are known as Porosphaera. This identification has been confirmed by Mr Paul Ensom, formally of the Natural History Museum. Kenneth Oakley's paper on the 'Folklore of fossils' published in an early volume of 'Antiquity' discuss the use of these fossils as beads during the early Bronze Age. It is impossible to tell if a Porosphaera fossil has been used as a bead unless it was found in an archaeological context or had been modified in some way. The assumption must be that stray finds are natural. See PAS record CAM-127600, CAM-3BF965 & DEN0-26AB57. |
