Abstract

An impression of the actinal surface of a starfish, possibly Calliderma, has been found at Loch Aline, N.W. Argyllshire, in Cretaceous white sandstone which hitherto has yielded no fossils. Indistinct traces of the ambulacral groves are present, otherwise only the outline is clearly defined. Carbonaceous matter associated suggests the fossil may have been desiccated in dry sand. The sandstone itself is a marginal deposit with millet seed frosted quartz grains of which the perfect rounding is masked by outgrowths of authigenic quartz.
