“…It is likely that Tropidoleptus migrated to the Paraná Basin from the Parnaíba and/or Amazonas basins during this transgression episode, supporting the idea that elements of the boreal fauna could colonize southern environments during the Devonian. This migration of invertebrates from the Parnaíba and Amazonas basins to the Paraná Basin in the Eifelian/Givetian transition, associated with the transgression of warmer waters, also is observed in echinoderms (e.g., Scheffler et al, 2011, 2017; Scheffler, 2015).…”

Tropidoleptus is a brachiopod genus with a very peculiar morphology that existed throughout the Devonian as a cosmopolitan taxon. Although there have been reports of the presence of this genus in the Paraná Basin since the nineteenth century, its actual occurrence has been the subject of much debate. The objective of this paper was to clarify this situation. For this purpose, dozens of specimens from Monjolo dos Padres and Juscimeira outcrops (São Domingos Formation, possibly Givetian) in the Brazilian state of Mato Grosso were analyzed. The samples studied here exhibit the typical characteristics of Tropidoleptus, confirming that this genus also occurred in the Paraná Basin. It is possible that Tropidoleptus entered the Paraná Basin during the Eifelian/Givetian from the Amazonas and/or Parnaíba basins (Brazil), during a period of warm-water transgression. When Tropidoleptus is found in situ, it can serve as an indicator of a shallower water environment (shoreface to shallower portions of transitional offshore). In the Paraná Basin, its presence can indicate rocks no older than the Eifelian–Givetian transition.

“…Estudos com crinoides, contudo, são raros (e.g., Lane, 1964). No Devoniano, são registrados nos arenitos das bacias do Amazonas, formações Maecuru e Ererê (e.g., Katzer, 1933;Scheffler et al, 2014Scheffler et al, , 2015, Parnaíba, formações Pimenteira e Cabeças (e.g., Scheffler et al, 2010Scheffler et al, , 2011 e Paraná, formações Ponta Grossa e São Domingos (e.g., Ferreira & Fernandes, 1985;Scheffler et al, 2017). Estas bacias compartilham táxons em comum dos gêneros Exaesiodiscus, Laudonomphalus e Monstrocrinus, sugerindo alguma comunicação e rotas de migração de crinoides durante o Devoniano (Scheffler et al, 2010).…”

Crinoidea from the Pennsylvanian deposits of the Itaituba Formation, Northern Amazonas Basin. The Itaituba Formation comprises part of the marine section of the Tapajós Group in the Amazonas Basin. This unit mainly comprises Pennsylvanian carbonate deposits associated with various marine invertebrate fossils. In this work, we present new records of crinoids in the Itaituba Formation in the Caltarém quarry, north platform of the Amazonas Basin. There are described and taxonomically identified, two genera of crinoids, through the study of columnals and pluricolumnals, in addition to the interpretation of the depositional environment through the analysis of carbonate microfacies. The identified specimens correspond to the species Cyclocaudex aff. typicus Moore & Jeffords, and to the genus Pentaridica Moore & Jeffords (first record in the Itaituba Formation). The textural, compositional, and paleontological analysis suggests four standard microfacies MPF 09, 10, 16, 23) and two faciological zones (ZF 7 E 8). The bioturbated bioclastic wackestones (MFP 09) and bioclastic wackestones/packstones (MFP 10) microfacies, with fossils of brachiopods, crinoids, echinoids, miliolid and fusulinid foraminifera, trilobites, and bryozoans, characterize an interior shelf environment, with a connection to an open marine circulation (ZF 7). The peloidal wackestones (MFP 16) and mudstones (MFP 23) microfacies, with a fossiliferous assemblage limited to brachiopods, echinoids and miliolid foraminifera, characterize a restricted lagoon environment (ZF 8). Paleontological data and microfacies analysis indicate the development of a lagoon environment with a diverse paleofauna of marine invertebrates in the carbonate platform of the northern bord of the Amazonas Basin, in the Monte Alegre County, during the Pennsylvanian. Keywords: taxonomy, echinoderms, microfacies, paleoenvironment, Pennsylvanian.
