“…Raistrick, along with his collaborator Kathleen Blackburn, continued work on palynology ranging from Quaternary to Carboniferous studies after his move to Newcastle; a key addition in terms of NPP research was their confirmation that the Carboniferous algae noted by Thiessen many years earlier were indeed Botryococcus, and indistinguishable from their modern counterparts (Marshall, 2005). Again, during the same period in the mid-1920s, I. Cookson was in residence in Britain, first at Imperial College London, then at the University of Manchester (Dettmann, 1993;Riding and Dettmann 2013); it is likely that she, too, was catalysed by lectures from Erdtman and Thiessen, although her interest in fossil plants and fungi was already developing: Cookson was trained as a modern botanist and mycologist in Australia, but turned her attention to palaeobotany and palaeomycology while in the UK; this collaboration produced many notable works, most importantly her seminal paper on Cenozoic fungi (1947).…”
