Palaeoart (not to be confused with Palaeolithic art, i.e. cave paintings) has a long and rich history of artworks that have helped us imagine the prehistoric past, from dinosaurs and mammals to cavemen. As an art genre though, it is largely ignored and looked down upon a bit, popular as these images are with children and the unwashed masses. This book aims to set the record straight and celebrate a carefully curated selection of palaeoart covering some 150 years, from the first works in the 1830s up to the 1980s. The book calls itself a two-fold time machine. Or, to paraphrase American artist Walton Ford in his preface, the book is a look back in time at what looking back in time looked like.
