The paleoentomofauna of the Crato formation (Lower Cretaceous; Araripe Basin): systematics and paleoecology


The Crato Formation (Araripe Basin, Northeastern Brazil) is considered one of the most important Lower Cretaceous Konservat-Lagerstätten in the world, internationally known by the exceptional level of preservation of its fossils. In the paleontological record of the Crato Formation, the insects stand out in diversity and richness. Different stages such as larvae, nymphs and adults of a wide variety of taxa occur. The purpose of this project is to create a new active network of international collaboration to study paleoentomology of the Crato Formation, to address taxonomic, phylogenetic and paleoecological issues. 1-Taxonomic studies: include mainly the taxonomic revision of insect taxa described for Crato Formation, and descriptions of new taxa. Recent recovery of an important part of the nomenclative types of the Martins-Neto Collection (about 50 holotypes, supposed to be lost during the past 10 years) opens up new possibilities for revisionary studies. 2-Phylogenetic studies: Whenever possible, taxonomic data will serve as a basis for inferring the phylogenetic relationships between taxa. 3-Paleoecological studies: Studies of the Crato Formation insect fauna in an ecological context have seldom been carried out. However, there is great potential to be explored, with possible implications for a more accurate understanding of the nature of the Crato Formation's paleoenvironment and its surroundings. New collections of Crato insect fossils are being assembled in different Brazilian Institutions, such as Universidade Federal do ABC (Santo André) and Universidade Federal do Mato Grosso (Cuiabá). Shared specimens databases will be built for these collections, allowing the interchange of data and collaborative work with several different specialists. (AU)
