Dixon studied geology and palaeontology at the University of St. Andrews and is best known for his illustrated works of speculative fiction, which largely concern "zoologies of the future": his own visions of how human beings and animals might evolve in millions of years' time. He is the younger brother of Douglas Dixon.
