Paleogeographic reconstructions are presented for the Lower and Middle Devonian of Brazil
(Siegenian—Givetian), following a brief account of Brazilian Devonian stratigraphy and …

A miospore biozonation, including 17 new interval zones, is proposed for Devonian–Early
Carboniferous stratigraphic sections in the Amazon Basin. It results from a detailed review of …

The classical Devonian rock units in the Apucarana Sub-basin (Paraná Basin), ie Ponta
Grossa shales, Tibagi sandstones and São Domingos shales were defined by Oliveira …

Abstract The Malvinokaffric Realm is an endemic paleogeographic region that inhabited
Gondwanan high latitude seas during Early-Middle Devonian times. The causes for the …

Differences in faunal composition of contemporary Devonian marine communities in
Brazilian sedimentary basins suggest variation because of climatic gradients. Temperatures …

Abstract The Devonian Period is characterized by an overall mean sea-level higher than is
observed today. This pattern is recognized in several basins worldwide and permitted, for …

Abstract An earliest Givetian “Lilliput Effect” at Sítio Wolff and São Bento in the Paraná Basin
occurred after an extinction event, possibly related to the latest Eifelian KAČÁK Event. The …

Previous studies of the Paraná Supersequence (Furnas and Ponta Grossa formations) of the
Paraná Basin in southern Brazil have yielded disparate sequence stratigraphic …

The geometry and petrology of sedimentary rocks preserved in the three intracratonic basins
of the Brazilian craton (Paraná, Parnaiba, and Amazon) indicate the history and character of …

Ichnology is an important tool for facies and sequence stratigraphic analysis, typically
yielding greater resolution than that provided by body fossils. Less commonly, ichnofossils …
