Sistemática E Tafonomia Dos Crustáceos Decápodes Da Ecofácies Capanema Da Formação Pirabas (Mioceno Inferior), Estado Do Pará

Our knowledge of fossil crustaceans from the tropics has increased considerably during recent decades, thanks to novel findings and the reexamination of museum specimens. However, several previous records have original arTiCle been misidentified, numerous museum specimens have never been reported, and many new discoveries are yet to be published. Here, we present a detailed, up-to-date, and revised checklist for every marine, terrestrial, or freshwater fossil decapod crustacean occurrence from tropical America known to us, including their age, geographic occurrences, and related literature. We recognize the occurrence of at least 32 superfamilies, 69 families, 190 genera, and 415 species of brachyurans ('true' crabs), and anomurans ('false' crabs, hermit crabs, squat lobsters, and allies), several of them previously unknown. The checklist comprises records from three main geographic regions: 1) northern South America (Bolivia, Brazil, Chile, Colombia, Ecuador, Peru, Venezuela); 2) Central America and southern North America (Belize, Costa Rica, Honduras, Panama, Mexico, southern and central Florida); and 3) the Caribbean Islands + Bermuda (Anguilla, Antigua, Aruba, Bahamas, Barbados, Bermuda, Bonaire, Cuba, Curaçao, Dominican Republic, The Grenadines, Haiti, Jamaica, Puerto Rico, Saint Bartélemy, Saint Martin, Trinidad). Previous findings, new occurrences, and the revised systematic placement for several problematic/misidentified records, indicate that the fossil record of anomurans and brachyurans in tropical America is more diverse than previously envisioned, with a considerable degree of endemism at the genus-and species-levels.

Testas que permaneceram por período de tempo maior sob a infl uência desse processo tafonômico, entretanto, se fragmentaram.…”

RESUMEN:Las variaciones verticales en el contenido de las asociaciones de foraminíferos, detectadas por medio de estudios cuantitativos y cualitativos, permitieron el reconocimiento de ocho biofacies en la Formación Pirabas, correspondientes a los subambientes de plataforma somera y lagunar. Los sedimentos fueron depositados en las áreas lagunares en función de las variaciones en la profundidad y la salinidad. La presencia de los foraminíferos planctónicos confirma la edad Mioceno Inferior para la Formación Pirabas. El registro de Globorotalia kugleri Bolli y Globigerinoides primordius Blow & Banner en la base y Globigerinoides altiaperturus Bolli y Globigerinoides trilobus trilobus (Reuss) en el tope del afloramiento puede ser correlacionado con las Zonas Bioestratigráficas Internacionales N4 y N5 de Blow (1969)
