Descrição de novos taxons de insetos fósseis dos membros Crato e Romualdo da formação Santana e comentários sobre a geodiversidade do Geopark Araripe, bacia sedimentar do Araripe, Nordeste do Brasil

Abstract

The Araripe Sedimentary Basin (ASB) is very promising in several aspects and mainly because it is a geological environment favorable to the existence of fossils of diverse taxa. In it is also located the Araripe Geopark, belonging to Global Geoparks Networks (GGN) and UNESCO Global Geoparks (UGG). In this thesis two new fossil insect occurrences are described: The first occurrence is a fossil specimen of insect in a calcareous nodule of the Romualdo Member of the Santana Formation “First Occurrence and Paleo-Ecological Implications of Insects (Orthoptera: Ensifera Gryllidae) in the Romualdo Member of the Santana Formation, Eo-Cretaceous of the Araripe Basin” (Published). The other is the first occurrence of a fossil specimen of Hymenoptera (Insecta) of the Siricoidea Superfamily from the Crato Member of the Santana Formation. “New species of Hymenoptera (Insecta) for the Eo-Cretaceous of the Araripe basin, Brazil” (Submitted). The geodiversity found in Araripe Geopark is commented on in chapter “Geodiversidade Conceitos, Aplicações e Estado da Arte no Brasil: Uma Aplicação ao Geopark Araripe” (Published) containing the necessary revisions for the realization of the research regarding the geodiversity of the Araripe Sedimentary Basin and the Santana Formation, geological unit of origin of the two fossil specimens analyzed in the previous items. The new fossil species described here, with holotypes housed in Brazil, contribute to the inventory of the paleontological heritage of the BSA, being some of the few fossil insect holotypes of the ASB in Brazil, creating possibilities of comparisons, revisions and reclassifications both taxonomic and characteristics of geological-environment units of Geodiversity.
