The paleontological heritage of northern Tocantins state and southwest Maranhão state, Brazil: a preliminary synthesis

Abstract

This paper aims to present a preliminary synthesis of the Paleontological Heritage of northern Tocantins State and southwest Maranhão State. It is a compound mainly from Paleozoic and Mesozoic rocks of the intracratonic Parnaíba Basin. Fossils from these regions include body fossils of sharks, gymnosperm trunks, mineralized ferns, ichnofossils of sauropods and theropods, and indeterminate leaf molds.Este trabajo tiene como objetivo presentar una síntesis preliminar del patrimonio paleontológico de la región norte del estado de Tocantins y suroeste de Maranhão, principalmente de las rocas de génesis paleozoica y mesozoica de la Cuenca Intracratónica de Parnaíba. Los fósiles consisten en somatofósiles de tiburones, gimnospermas y troncos de helechos mineralizados, icnofósiles de saurópodos y terópodos, y moldes de hojas indeterminadas.
