From hystrichospheres to dinoflagellate cysts: Scandinavian contributions to Evitt’s pivotal recognition of fossil dinoflagellate cysts [PDF]

Palynology, 2020
As one of the remaining living links with two early Scandinavian researchers, the author examines their contribution to Bill Evitt’s breakthrough that launched the development of fossil dinoflagellate cysts into palynology. Evitt, in the early 1960s, revealed that many fossil hystrichospheres were in fact dinoflagellate cysts.
