John Sibbick is a British freelance illustrator and paleoartist best known for his fantasy art and reconstructions of prehistoric life in several media. Sibbick studied Graphics and Illustration at Guildford School of Art (now University for the Creative Arts) in the south of England. Thereafter he worked for design studios in London, embarking upon a career as a freelance illustrator in 1972. Sibbick's colour work is executed in gouache on artist's board, and often benefits from the production of detailed preparatory sketches and even 3D models for reference.
