Gardiner was appointed an assistant lecturer in palaeontology at Queen Elizabeth College in 1958, and was later made Professor of Palaeontology at the Department of Biology at the same college. Queen Elizabeth College later merged with King's College London (1985). In 1963, he worked on secondment at the University of Alberta, Edmonton.[3][4] In 1969, Gardiner described seven new genera and species of palaeoniscid fish from the Witteberg Series in South Africa.[5] He was president of the Linnean Society of London 1994–1997, and was later made a Fellow Honoris Causa of the same society.[1] He was an advisor on palaeontology to the Natural History Museum in London.
