'Reginald Sprigg', A.O. D.Sc., h.c. A.N.U. & Flinders University, (born
1 March 1919, died
2 December 1994). Reg was a well known
Australian
geologist. He is perhaps best remembered internationally as the discoverer of the
Ediacara biota, an assemblage of some of the most ancient animal
fossils known, at
Ediacara Hills in
South Australia.
Career
Reg Claude Sprigg was born on
1 March 1919 in
Stansbury, a small town on the
Yorke Peninsula in
South Australia. His original qualifications were gained at the
University of Adelaide, with a
Master of Science in
geology gained in 1941. In
1940 he enlisted in the
Australian Royal Engineers, and was in Munitions from 1941 to
1942. He moved to work with the
soils division in
CSIRO until 1943.
Reg next worked for the
South Australian Geological Survey, who sent him to reopen the
Radium Hill Uranium Field in 1944, and to map the
Mount Painter uranium field. At the time, uranium was believed to be rare, and was required for the
Manhattan Project. Uranium from these mines were used to manufacture British nuclear weapons but was not ready in time for the first atomic bomb.
When Reg discovered the fossils at Ediacara Hills in 1946 the sun was low in the sky, thus able to cast shadows increasing the visibility of the shallow fossil impressions on the rocks. He realised that these fossils were very ancient, either of Early
Cambrian, or possible even of
Precambrian age. He published and promoted his finds, and subsequent work by Prof
Martin Glaessner at the University of Adelaide demonstrated that they were indeed of latest
Precambrian age. Although Precambrian animal fossils had been reported before, they had not been universally accepted as organic. This discovery led ultimately to the recent erection of the
Ediacaran Period, the first new
geological period created in over one hundred years.
In 1951 he married Griselda Paterson and fathered two children, Margaret and Douglas.
Of other significance, he helped set up
SANTOS (South Australia Northern Territory Oil Search), which discovered the gas deposits in Cooper Basin, including the Moomba Gas Field. This supplies natural gas to New South Wales and
Canberra. He was granted the officer of the Order of Australia in 1983. He owned the company Geophysical Surveys which was a consulting and contracting company for geological and geophysical work. They prospected for uranium in the Northern Territory and
nickel in the north west corner of South Australia as well as working for SANTOS.
In 1962 Geophysical Surveys became incorporated into Beach Petroleum.
In 1968 Sprigg purchased
Arkaroola, a property in South Australia, and turned it into a wildlife refuge and tourist attraction.
The Royal Society of South Australia awarded him the Verco medal in 1968.
Reg Sprigg died on
2 December 1994.
