Thomas Stanley Westoll (3 July 1912 – 19 September 1995) was a British geologist, and the long-time head of the Department of Geology at Newcastle University.
He then studied Sciences on a scholarship at Durham University, specialising in geology and palaeontology, graduating BSc in 1932.
In 1937 he began lecturing in Geology and Mineralogy at Aberdeen University, his central interest being the study of fossil fish.
[2] In 1948 he left Aberdeen to return to England as Professor of Geology at the University of Newcastle, staying there until his retirement in 1977.
[4][5] The citation on his application read: "Westoll is a palaeontologist who by his description of new materials and by the introduction of new and fertile ideas into the interpretation of the structure of early fossil vertebrates has greatly increased our understanding of the problems they present.
