Paleoicnologia do Siluro-Devoniano do estado do Paraná e a obra de John Mason Clarke Paleoicnhology of the Silurian-Devonian from Paraná State (southern Brazil) and the work of John Mason Clarke Paleoicnología del Siluro-Devónico del estado de Paraná y la obra de John Mason Clarke

The Silurian-Devonian beds of Parana State (southern Brazil) are notoriously rich in ichnofossils and several ichnological studies were carried on since the work of John Mason Clarke, in 1913. This study presents the historical record of the ichnological research in the Silurian-Devonian beds of the Parana State. Most of the studies were focused on the Furnas Formation and emphasized preferentially the ichnotaxonomic characteristics, although some ichnofaciological aspects have been considered. Even being discrete, the contribution of Clarke to the ichnology of Silurian-Devonian beds from Parana State was relevant to address an issue that was not yet featured in the earth sciences in the early 20 th century.
