Dinosaurs and other prehistoric animals have always fascinated people but they pose vast problems for the artist. How do you go about recreating the anatomy and behaviour of a creature we've never seen? How can we restore landscapes long lost to time? And where does the boundary between palaeontology - the science of understanding fossils- and artistic licence lie? In this outstanding book, Mark Witton shares his detailed paintings and great experience of drawing and painting extinct species. The approaches used in rendering these impressive creatures are discussed and demonstrate the problems, as well as the unexpected freedoms, that palaeontological artists are faced with. The book showcases over ninety scientifically credible paintings of some of the most spectacular animals in the Earth's history, as well as many less familiar species.
