“…Oil company paleontologists (Armstrong, 1953;Malloy, 1955a, 1955b;Kuyl, Muller, and Waterbolk, 1955;Norem, 1955;Wilson and Hoffmeister, 1955;Woods, 1955) are taking practical advantage of the relative abundance of spores and pollen to hystrichosphaerids and other fossils in well samples. Armstrong (1953) reports that fossil spores and pollen occur in about 45 percent of well cuttings examined, whereas Foraminifera and larger fossils are normally present in less than 1 percent.…”

“…This three-man team confirmed that palynomorphs were indeed excellent stratigrapical index fossils. This conclusion was simultaneously being drawn elsewhere in the United States (Woods 1955a(Woods , 1955bWilson 1956Wilson , 1961Grayson 1960). Additionally, Isabel C. Cookson and her collaborators were investigating stratigraphical palynology in Australia at this time (e.g.…”

Occasionally (and fortunately), circumstances and timing combine to allow an individual, almost singlehandedly, to generate a paradigm shift in his or her chosen field of inquiry. William R. ('Bill') Evitt (1923À2009) was such a person. During his career as a palaeontologist, Bill Evitt made lasting and profound contributions to the study of both dinoflagellates and trilobites. He had a distinguished, long and varied career, researching first trilobites and techniques in palaeontology before moving on to marine palynomorphs. Bill is undoubtedly best known for his work on dinoflagellates, especially their resting cysts. He worked at three major US universities and spent a highly significant period in the oil industry. Bill's early profound interest in the natural sciences was actively encouraged both by his parents and at school. His alma mater was Johns Hopkins University where, commencing in 1940, he studied chemistry and geology as an undergraduate. He quickly developed a strong vocation in the earth sciences, and became fascinated by the fossiliferous Lower Palaeozoic strata of the northwestern United States. Bill commenced a PhD project on silicified Middle Ordovician trilobites from Virginia in 1943. His doctoral research was interrupted by military service during World War II; Bill served as an aerial photograph interpreter in China in 1944 and 1945, and received the Bronze Star for his excellent work. Upon demobilisation from the US Army Air Force, he resumed work on his PhD and was given significant teaching duties at Johns Hopkins, which he thoroughly enjoyed. He accepted his first professional position, as an instructor in sedimentary geology, at the University of Rochester in late 1948. Here Bill supervised his first two graduate students, and shared a great cameraderie with a highly motivated student body which largely comprised World War II veterans. At Rochester, Bill continued his trilobite research, and was the editor of the Journal of Paleontology between 1953 and. Seeking a new challenge, he joined the Carter Oil Company in Tulsa, Oklahoma, during 1956. This brought about an irrevocable realignment of his research interests from trilobites to marine palynology. He undertook basic research on aquatic palynomorphs in a very well-resourced laboratory under the direction of one of his most influential mentors, William S. 'Bill' Hoffmeister. Bill Evitt visited the influential European palynologists Georges Deflandre and Alfred Eisenack during late 1959 and, while in Tulsa, first developed several groundbreaking hypotheses. He soon realised that the distinctive morphology of certain fossil dinoflagellates, notably the archaeopyle, meant that they represent the resting cyst stage of the life cycle. The archaeopyle clearly allows the excystment of the cell contents, and comprises one or more plate areas. Bill also concluded that spine-bearing palynomorphs, then called hystrichospheres, could be divided into two groups. The largely Palaeozoic spine-bearing palynomorphs are of uncertain biological affin...

“…Literature compilations in palynology are not simply tedious lists During the 1950s, 1960s and 1970s, pre-Quaternary palynology expanded at a phenomenal rate due largely to the exponential increase in the use of palynomorphs as marker fossils by the oil and gas industry worldwide (Woods 1955;Wilson 1961). Research activity in Quaternary palynology also increased substantially at the same time (Erdtman 1958).…”
