Joan Marion Crockford-Beattie (January 1919 – 2015) was an Australian geologist and palaeontologist who specialised in Permian bryozoan faunas.
Wartime restrictions also affected research, with makeshift motors being devised in the Physics department to run the slide-making tools,[1] and materials having to be mailed to her from colleagues in Queensland (Dorothy Hill), Tasmania and Western Australia (Curt Teichert), rather than conducted on site.
She continued working on her D.Sc., completing papers on Bryozoa with the help of specimens and thin sections she took with her and from staff at the Australian Museum.
The family moved to a number of locations due to George Beattie's work as a mining engineer including Cracow, Queensland[7] and Radium Hill.
She erected two families and seven genera—Pesnastylus, Minilya, Streblocladia, Stenodiscus, Etherella, Evactinostella and Liguloclema—as well as an estimated 100 other species of Bryozoa.
