Upper Carboniferous Plant Spore Assemblages from the Gastrioceras subcrenatum Horizon, North Staffordshire

Abstract

From a locality in North Staffordshire. Microspore assemblages are described from the Six Inch Mine coal seam, the immediately overlying carbonaceous shales, and the marine shale bed. Marked differences occur within this thin sequence in the proportions of certain genera present; in particular, the dominance of Florinites in the marine shales is discussed. Whilst the proportionate numbers of genera vary, the actual species present are more or less the same, though a greater variety exists in the shales. Three new genera and seven new species are described.
