The global dispersal of forests and soils has been proposed as a cause for the Late Devonian mass extinctions of marine organisms, but detailed spatiotemporal records of forests and soils at that time remain lacking. We present data from microscopic and geochemical analyses of the Upper Devonian Chattanooga Shale (Famennian Stage). Plant residues (microfossils, vitrinite and inertinite) and biomarkers derived from terrestrial plants and wildfire occur throughout the stratigraphic section, sugges...

Abstract We present a new biostratigraphically constrained carbon isotope record from the Lali section (South China) to document perturbations in the Late Devonian carbon cycle. Positive carbon isotope excursions (CIEs) are most important components of the Late Devonian long-term carbon isotope cycle: Frasnes (+2‰), Middlesex (+1‰), Lower Kellwasser (+3‰), Upper Kellwasser (+3‰) and Upper annulata (+1‰) events, as well as a small positive CIE (+1‰) in the Famennian expansa-aculeatus zones were r...

Abstract The Lali section (Guangxi Province, South China) is composed of quiet-water carbonates containing abundant conodonts, which allowed recognition of 12 Frasnian and 20 Famennian biozones. The Kellwasser and annulata events are characterized by transgressive black carbonates, while the Hangenberg Event is represented by black shale deposits. Other transgressive events recognized at Lali include the Middlesex, Nehden, Enkeberg, and Dasberg, as well as the Strunian transgression. Four regres...

Abstract Recognition of stratigraphic hiatuses in fine-grained siliciclastic sedimentary rocks can be challenging but is feasible using high-resolution biostratigraphic and chemostratigraphic data within a regional correlation framework. In this case study of the Upper Devonian Chattanooga Shale in the Dupont GHS drillcore from the western margin of the Nashville Dome, the Upper Devonian Chattanooga Shale comprises several depositional units separated by intraformational hiatuses. These features...

Abstract This paper reports for the first time the presence of Famennian conodonts from a shallow marine succession exposed in the Cerro La Cueva, central Sonora, northwestern Mexico. The conodont fauna includes Bispathodus aculeatus aculeatus (Branson and Mehl) , Bispathodus stabilis (Branson and Mehl), ‘ Icriodus ’ darbyensis Klapper, Polygnathus extralobatus Schafer, Polygnathus semicostatus Branson and Mehl, Polygnathus cf. inornatus E.R. Branson, and Polygnathus aff. purus Voges, which are ...

Abstract The Devonian-Carboniferous transition (359 Ma) was a time of extreme climate and faunal change and is associated with the end-Devonian biodiversity crisis. The transition is characterized by transgressive/regressive cycles, which culminated in the onset of widespread ocean anoxia (the Hangenberg Black Shale event) and a remarkable sea-level fall close to the Devonian-Carboniferous boundary (the Hangenberg Sandstone event); together these are known as the Hangenberg Crisis. The Hangenber...

Abstract Upper Devonian marine deposits of the Baruunhuurai Terrane in western Mongolia represent island arc settings, which yielded a diverse conodont assemblage of 30 taxa, including species of Ancyrognathus (as well as one new species), Icriodus , Mehlina , Polygnathus and Palmatolepis . Biodiversity analysis of Ancyrognathus , Pelekysgnathus , Mehlina and Icriodus shows that the Mongolian conodont assemblage consists of two endemic and few cosmopolitan taxa. Representatives of the otherwise ...

The Global Boundary Stratotype Sections and Points (GSSPs) for the bases of all seven international Devonian stages have been formally defined and ratified by IUGS till 1996, and nowadays, the main tasks for Devonian stratigraphers include further subdivision of these standard stages, strictly constrained absolute ages for the boundaries, and precise neritic-pelagic and marine-terrestrial correlations using multidisciplinary stratigraphy methods. Establishment of high-resolution Devonian integra...

The Kellwasser Crisis represents one of the most severe extinction events in the Phanerozoic. The Sumbera section (Moravo-Silesian Basin, Moravian Karst) spans the Upper rhenana to Palmatolepis minuta minuta (or younger) conodont zones and corresponds to the upper part of a carbonate ramp with material derived from shallower areas. A rich association of calcareous algae, cyanobacteria, and microproblematica, comprising renalcids (Izhella), Girvanella, Rectangulina cf. tortuosa, Rothpletzella, “s...
