“…The second major contribution was by Emily Dix (for details of her life, see Burek & Cleal, 2005). Dix's interests were mainly biostratigraphical, with her main studies around the Swansea Valley (Dix, 1928(Dix, , 1930(Dix, , 1932(Dix, , 1933(Dix, , 1934(Dix, , 1937. She also built up a valuable collection of fossil plants from the coalfield, which is now in the Hunterian Museum (Glasgow) and the National Museum Wales (Cardiff).…”

The South Wales Coalfield has the most complete Westphalian macrofloral record anywhere on the Variscan Foreland or adjacent basins, with 135 biodiversity-meaningful morphospecies having been recognized. All of the standard macrofloral biozones of the Westphalian Stage have been recognized, although a detailed comparison with the Central Pennines Coalfields has indicated some discrepancies in the relative positions of the biozonal boundaries. Total Species Richness progressively increases through the Langsettian Substage, and then remains relatively stable through most of the Duckmantian and Bolsovian substages. There is a distinct reduction in Total Species Richness towards the top of the Bolsovian Substage, but this partially recovers in the middle Asturian Substage with the appearance of a range of marattialean ferns, and medullosalean and callistophytaleans pteridosperms. There is no evidence of any significant drop in Total Species Richness towards the top of the succession, indicating that conditions at this time were relatively stable. The change from coastal floodplain to alluvial braidplain conditions in middle Bolsovian times correlates with a marked increase in the proportion of medullosalean remains being preserved in the adpression record, reflecting an expansion of the clastic-substrate habitats.

“…The lowest zone found in Northumberland and Durham is the zone of Neuropteris schlehani and Lyginopteris hceninghausi. Kich assemblages of plants characteristic of this zone are found in the roof of the High Shilford Coal, High Shilford Colliery (Dix, 1932(Dix, , p. 1065, and also in the strata associated with the Brockwell Seam. KIDSTON, however, stated that plants were scarce in these beds, and for this reason he placed all the strata from the Brockwell to the Carboniferous Limestone in the Lanarkian Series There appears to be some evidence for the existence of this zone in Durham from the examination of specimens collected at Offerton.…”

In 1925 Professor A. E. Trueman handed to the writer a copy of Professor Bertrand's paper, “Les Zones Végétales du Terrain Houiller du Nord de la France” (1914, p. 208), with the suggestion that it would be interesting to find out whether the succession of plants in South Wales is similar to that of the North of France, and to determine whether Bertrand's zones can be applied to the Coal Measures of South Wales. Since that time every opportunity has been taken to collect fossil plants from known horizons in South Wales and other coalfields. In addition, specimens have been examined in all the important museums and private collections, and in particular in the collections of the late Dr R. Kidston, which are now preserved in the Museum of Practical Geology.
