Mapeamento Paleontológico Da Pedra Cariri E Calcário De Lioz Em Edificações Na Cidade De Santarém – Pa

Abstract

The Araripe Basin, located in the Northeast of Brazil, and the Lusitânia Basin located in the Iberian Peninsula, are large fossil deposits, which offer important records of life during the Cretaceous period. Under this bias, the work proposes the mapping of fossil content belonging to the Cretaceous period, associated with the Cariri Stone (Araripe Basin) and the Lioz Limestone (Lusitânia Basin) found in buildings in the city of Santarém, Pará. The review was carried out bibliographical information about sedimentary basins, paleontological content and use of rocks. Subsequently, field work was carried out, in which four points in the city were visited, and photographic records were taken of the fossil content found. In view of the study, 5 fossils of fish from the Actinopterygii class, recorded in Pedra Cariri, and 7 fossils of molluscs from the Bivalvia class were identified. This work is significant, as it expands information about paleontological studies, and contributes to the identification and appreciation of the paleontological heritage present in the city of Santarém, Pará.
