The identification of avian and dinosaurian digits remains one of the major controversies in vertebrate evolution. A long history of morphological interpretations of fossil forms and studies of limb development in embryos has been given as evidence for two differing points of view. From an originally pentadactyl forelimb, either digits I, II and III form in the manus of birds and thus support a dinosaurian ancestry, or digits II, III and IV form in the manus supporting a more ancient ancestry or an evolutionary frame shift. A review of the history of research into the subject is presented here, dating from approximately 1825 to 2009.

Dinosaurs and Other Extinct Saurians: A Historical Perspective
The discovery of dinosaurs and other large extinct ‘saurians’—a term under which the Victorians commonly lumped ichthyosaurs, plesiosaurs, pterosaurs and their kin—makes exciting reading and has caught the attention of palaeontologists, historians of science and the general public alike. The papers in this collection go beyond the familiar tales about famous ‘fossil hunters’ and focus on relatively little-known episodes in the discovery and interpretation (from both a scientific and an artistic point of view) of dinosaurs and other inhabitants of the Mesozoic world. They cover a long time span, from the beginnings of ‘modern’ scientific palaeontology in the 1700s to the present, and deal with many parts of the world, from the Yorkshire coast to Central India, from Bavaria to the Sahara. The characters in these stories include professional palaeontologists and geologists (some of them well-known, others quite obscure), explorers, amateur fossil collectors, and artists, linked together by their interest in Mesozoic creatures.
