This preface gives a brief review of some of his accomplishments and a list of his publications to date. Peter Forey started his palaeontological career as a research student of Brian Gardiner at Queen Elizabeth College, University of London from — His thesis on elopiform fishes was published in in the Bulletin of the British Museum Natural History Geology supplement These publications are still the standard works on fossil elopomorph comparative anatomy.

Insometime after graduation during which period he had several jobs, including working for a security firm he applied for, and secured, the position of Assistant professor in Zoology at the University of Alberta. He remained in this post until when he joined the fossil fish section in the Department of Palaeontology at the Natural History Museum, London.

Here, working with Colin Patterson, he became one of the prime movers in getting phylogenetic systematics or cladistics as it became called accepted by the palaeontology community. This new method for analysing phylogenies was being developed in the s following the publication of a paper on phylogenetic systematics in English Hennig On the face of it, this was a publication describing the anatomical details of the snouts of tetrapods, lobe-finned fishes and lungfishes, and their conclusion was that tetrapods were more closely related to the lungfish rather than other lobe-finned fishes in particular the osteolepiformswhich was the accepted idea at that time.

This caused quite a stir but mainly because From: Geological Society, London, Special Publications,1—6.

They again argued in strong terms for cladistic methodology where relationships should be inferred from extant forms alone without reference to fossils.

Peter continued to champion cladistics and educate a new generation. His background in lecturing also proved important for the development of cladistics at the Natural History Museum when in Peter, together with Chris Humphries, David Williams, Darrell Siebert and Ian Kitching, set up a course on cladistics for museum staff and MSc students and was one of the lead lecturers.

He is without doubt the world authority on coelacanths. Peter has also published extensively on lungfishes, e. Foreyand their relationship to tetrapods Forey et al.

Peter Forey taking a short break from fossil collecting to make a study for a watercolour. All of this is borne out by the fact that he has published over peer-reviewed papers, 24 other articles and book reviews and written or contributed to 21 books and is still actively researching and writing.

Peter also paints watercolours and has exhibited and sold many paintings. His keenness extends to taking a sketchpad with him wherever he goes, even to the most remote and some would say artistically-uninspiring field areas Fig.
