This beautifully illustrated 2007 volume describes the entire flora and fauna of the famous Lower Cretaceous Crato Formation of Brazil - one of the world's most important fossil deposits, exhibiting exceptional preservation A wide range of invertebrates and vertebrates are covered, including extended sections on pterosaurs and insects Two chapters are devoted to plants Many of the chapters include descriptions of new species and re-descriptions and appraisals of taxa published in obscure places, rendering them available to a wider audience Fossil descriptions are supported by detailed explanations of the geological history of the deposit and its tectonic setting Drawing on expertise from around the world and specimens from the most important museum collections, this book forms an essential reference for researchers and enthusiasts with an interest in Mesozoic fossils

The Crato Fossil Beds of Brazil: Window into an Ancient World

The Araripe Basin comprises four main stratigraphic sequences separated by unconformities: 1. a Paleozoic sequence composed of the Cariri Formation; 2. a Juro-Neocomian sequence composed of the Brejo Santo Formation, Missao Velha Formation (redefined) and Abaiara Formation; 3. an Aptian-Albian sequence composed of the Barbalha Formation and Santana Formation; and 4. an Albian-Cenomanian sequence composed of the Exu Formation. The Juro-Neocomian sequence is characterized by horsts and grabens displayed in two sub-basins: Cariri and Serrolândia subbasins. The Aptian-Cenomanian is characterized by sub-horizontal bedding and localized brittle deformation. The events of sedimentation, erosion, and deformation proposed for the sequences above, integrate the Phanerozoic evolution in Northeastern Brazil. The Paleozoic deposits which have, in attempt, been classified as Upper Ordovician/Lower Silurian, have also been interpreted as an extension of the cratonic Parnaiba Basin. The Juro-Neoconian sequence is u» sedimentary response to the mechanical subsidence brought about by the Gondwana rifting processes. The Barbalha and Santana formations comprise a transgressive-regressive cycle characterized by short-lived sea ingression which has deposited an exuberant fossiliferous carbonate concretions level and extensive gypsum beds. The presence of alluvial deposits of Exu Formation, deposited contemporaneously to a global eustatic sea level rising, suggests an epeirogenic uplift early in the Albian-Cenomanian time.
