Edwards was born in Swansea, South Wales, and spent much of her time at her parents' bungalow on the Gower Peninsula.
[2] Edwards' work has centred on early plant fossils, the majority of which have been retrieved from the UK.
[3] Much of her later work has centred on the Rhynie chert and charcoalified fossils, large and microscopic, from the Welsh borderlands and South Wales.
[9] The charcoalified nature of many of her fossils have enabled her to prove that wildfires took place in the Siluruan period.
[13] She is the author or co-author of a considerable number of botanical names of fossil plants, such as Danziella D.Edwards (2006)[14] and Demersatheca C.-S. Li & D.Edwards (1996).
