Abstract
A bowl-like object recovered from the sea-bed off Shetland at approximately 60° 30' N., 0° 55' W. under 110 to 120 m. of water, is of problematical nature. It is pale grey, approximately conical, 33 × 30 cm. at the open end, 26 cm. high, with a suggestion of a foot. It is composed of a porous silty or sandy, apparently sedimentary, micaceous aragonite-limestone, containing numerous heavy mineral grains. The wall, 2 to 4 cm. thick, is irregular, with protuberances mainly on the inside. There is a plentiful microfauna, and apart from one specimen of Coccolithus, of Cenomanian age, it is entirely post-Glacial, probably modern. Some other objects are briefly discussed which may be similar or have a bearing on the origin of the Shetland ‘bowl’. There is some evidence of recrystallisation and it is suggested that the object, deposited as a calcareous mud off a metamorphic terrain (which Shetland is), may be the relic of a solution pipe, perhaps related to the submergence of te nearby coast.
