| Notes: | Searchable database of single grain Late Palaeozoic palynomorphs. Specimens collected worldwide but "most closely associated with the UK and north-west Europe." Entries for each taxon includes multiple specimen examples, " description, sources of alternative descriptions, details of size and stratigraphical range are given, compiled from the literature sources listed in the reference section and the personal records of the authors."
"Many of the taxa illustrated and described are integral to the biozonation of the Carboniferous of north-west Europe published by Clayton et al. (1977) and to earlier regional biozonations of smaller stratigraphical intervals within the UK (Smith and Butterworth, 1967; Neves et al., 1972, 1973; Owens and Burgess, 1965; Owens et al., 1977)."
All original slides held in the BGS Palaeontology Collections at Keyworth, Nottingham.
