The life and work of Emily Dix (1904–1972)
Emily Dix was a leading British palaeobotanist during the first half of the 20th century to deal with the stratigraphical distribution of macrofloras. She helped transform the use of fossil plants in defining biostratigraphic units in the Carboniferous strata in Britain; her plant-based zonation remains the foundation of Carboniferous macrofloral biostratigraphy today. She addressed several problems that came to dominate Carboniferous stratigraphical research during the second half of the century, including the mid-Carboniferous boundary and the Westphalian-Stephanian boundary. Her career was tragically cut short by mental illness when she was only in her early 40s.
