Palynological assemblages are described from new exposures of Coal Measures in the Titterstone Clee Coalfield, Shropshire, England. The composition of taxa present in the assemblages is indicative of the presence of three miospore zones, SS, RA and NJ, forming part of the Langsettian and Duckmantian regional stages (Westphalian A - early Westphalian B age). The colour of the spores in the assemblages from strata immediately above the upper surface of the Titterstone Clee Dolerite compared with those of more widely separated assemblages indicates a marked thermal effect, confirming that the dolerite is intrusive.
