Abstract

Points out that definitive Tournaisian (lower Carboniferous) species are present in the Solenopora subzone at Ravenstonedale, Westmorland, northwest England, and that not only this bed but the Pinskey Gill beds below are Tournaisian, rather than Visean as stated by T. N. George . Beds correlated with the Ravenstonedale series therefore are Tournaisian. Definitive Tournaisian species are also present in the Dublin region, Ireland.
