Dixon has written well over a hundred books on geology and palaeontology, many of them for children, which have been credited with attracting many to the study of the prehistoric animals.

At present, he lives in Wareham, Dorset, where he works as a full-time author and book editor and also manages a local movie theatre.

Dixon has contributed to the movement following the publication of his trilogy, for instance publishing the book Greenworld in 2010 and serving as a consultant and contributor to the 2002 miniseries The Future is Wild.

[3] He credits the beginning of his writing career as being spawned from his love of creating stories, usually in the form of comic strips, as a child.

[6] Dixon's research thesis focused on palaeogeography,[3][7] tracing the different landscapes of the British Isles throughout their geological history.

He also did teaching work from 1993 to 2005, sponsored by the publishing company Boyds Mills Press as a visiting lecturer at elementary schools in the United States, giving presentations about dinosaurs.

In 1995, he partook in an Open University/Earthwatch expedition to Askja Caldera, Iceland, and in 1987, Dixon was one of the excavators at a Jurassic-aged dinosaur-rich fossil site in Durlston, Dorset.

[15] Dixon himself considers his palaeontology and geology books, due to inspiring others to take an active interest in these fields, to be his greatest contribution to science.

[7] He has also noted that the speed in which new palaeontology discoveries are made today often render portions of his books outdated before they are even published.

[3][16] He has also hosted a Japanese programme on evolution, during which he travelled across the world, visiting, among other locations, the Galápagos Islands and the Serengeti.

His ideas have been repurposed or used as inspirations for numerous similar projects, both in print and on the internet,[18] and have in some cases spawned adaptations and exhibitions.

[6] Dixon served as a consultant and creature designer for the miniseries The Future is Wild (2002) and also co-authored its companion book with the series producer Joanna Adams.

[3] Dixon has stated that he mostly reads science fiction stories from the "golden age", by writers such as Brian Aldiss, Arthur C. Clarke, Robert Silverberg and Clifford D.
