Cover Story: By the late 19th century, Paul Choffat and Henri Sauvage had laid the foundations for the study of vertebrates from the Upper Cretaceous of western Iberia, making a major contribution to European palaeontology of the time. These assemblages occur in carbonate platform, marginal marine, and terrestrial facies that characterised the Late Cretaceous Palaeo-Atlantic margin of the European archipelago. They exhibit predominantly Tethyan affinities while also indicating links with North African, northern, and eastern European faunas. The record includes chondrichthyans, actinopterygians, amphibians, turtles, crocodylomorphs, and squamates, and is notable for the latest Cretaceous small-bodied dinosaurs and mammals. Recent discoveries of new fossil sites have expanded knowledge of these faunas and have led to the recognition of new taxa. View this paper
