On the occurrence of foraminiferans in the lower Cambrian of the Llangynog inlier, South Wales

Microfossils obtained from dissolution of a limestone horizon from the lower Cambrian Allt y Shed Sandstone of the Llangynog Inlier, Carmarthenshire, South Wales, are identified as agglutinated foraminiferans. Two genera and three species are represented and are figured. These microfossils add further to the scanty record of Cambrian foraminiferans, but do not resolve the problem of the precise age of the Allt y Shed Sandstone.
