, Leicester. Decades later it was revealed that
Tina Negus, then a 15-year-old schoolgirl, had seen this fossil a year before the boys,
but her geography schoolteacher discounted the possibility of Precambrian fossils.
Mason acknowledges, and the museum's Charnia display explains, that the fossil had been discovered a year earlier by Negus, "but no one took her seriously".
["In April 1957, I went rock-climbing in Charnwood Forest with two friends, Richard Allen and Richard Blachford ('Blach'), fellow students at Wyggeston Grammar School, Leicester. I was already interested in geology and knew that the rocks of the Charnian Supergroup were Precambrian although I had not heard of the Australian fossils. Richard Allen and I agree that Blach (who died in the early 1960s) drew my attention to the leaf-like fossil holotype now on display in Leicester City Museum. I took a rubbing and showed it to my father, who was Minister of the Great Meeting Unitarian Chapel in East Bond Street, taught part-time at University College (soon to be Leicester University) and thus knew Trevor Ford. We took Trevor to visit the fossil site and convinced him that it was a genuine fossil. His publication of the discovery in the Journal of the Yorkshire Geological Society established the genus Charnia and aroused worldwide interest. ... I was able to report the discovery because of my father’s encouragement and the enquiring approach fostered by my science teachers. Tina Negus saw the frond before I did but no one took her seriously."] She was recognised at the 50th anniversary celebrations of the official discovery.
Mason's discovery was mentioned by the February 2009

documentary ''Charles Darwin and the Tree of Life'', and again in Attenborough's 2010 series ''First Life'' and the documentary that accompanied it, ''Attenborough's Journey''. Attenborough, a keen fossil hunter as a boy, mentioned that he attended Wyggeston a few years prior to Mason, and had been in the same part of Charnwood a few years before Mason, but the prevailing wisdom at the time was that the rocks were too old to bear fossils and so Attenborough did not search for them.
