| Resumo: | Echinoids from Jandaíra Formation, Upper Cretaceous, Potiguar Basin, Northeastern Brazil. The present paper analyzes the studies about fossil echinoids from the Jandaíra Formation, Upper Cretaceous, Potiguar Basin, Northeastern Brazil, with the purpose of showing the current knowledge about the species of the geological unit. The bibliography was obtained by searching websites such as Scholar Google, Memória da Biblioteca Nacional, Biodiversity Heritage Library, and Periódicos Capes. Furthermore, we contacted several researchers in the area of study, looking for access to any missing bibliography. We surveyed 32 studies, including monographs, dissertations, abstracts, papers in scientific journals, and book chapters. A timeline was produced for each species. We concluded that are fourteen valid species for the formation: Petalobrissus lehugeurae Alves; Petalobrissus setifensis Cotteau; Petalobrissus cubensis Weisbord; Mecaster texanus Roemer; Mecaster fourneli Agassiz & Desor; Hemiaster cearensis Brito; Hemiaster catandubensis Maury; Mecaster sp.; Rosadosoma riograndensis (Maury); Phymosoma major Coquand; Goniopygus durandi Perón & Gauthier; Coenholectypus upanemensis Beurlenou Coenholectypus serialis gp.?; Phymosoma sp.; and Pygorhynchus sp.?. A considerable diversity. However, apart from taxonomy, few studies address other subjects such as paleoecology, taphonomy, biogeography, and stratigraphy. The observations raised, help to understand the taxonomic history of the echinoid species. Accordingly, they might indicate the direction of future studies about echinoids of the Jandaíra Formation |
