Microbial mounds prior to the Frasnian-Famennian mass extinctions, Hantang, Guilin, South China

, 2010
Late Frasnian mounds of the Yunghsien Formation, Guilin, South China, developed as part of the Guilin platform, mostly in reef-flat and platform margin settings. Microbial mounds in platform margin settings at Hantang, about 10 km west of Guilin, contain

Parasitism as a Long-Lasting Interaction-First Evidence From Paleozoic Corals. [PDF]

Ecol Evol
The peak of reef development in the middle Paleozoic resulted in a dense network of interactions between corals and their symbionts. The long duration (longevity) of one of the most common relationships, parasitism, has remained unevidenced so far. Here we report on a tabulate coral infested by parasites, where, based on growth bands, the duration of ...

Enhanced continental weathering and its marine environmental effects in the late Devonian: Constraints from strontium isotopes of carbonate rocks in South China

地质科技通报, 2022
The Frasnian-Famennian extinction in the late Devonian was one of the largest mass extinction during Earth's history, which was believed to be caused by the plant landing-indued intensification of terrestrial chemical weathering and the consequent ...

Bioerosion in the Late Devonian placoderm remains from the Holy Cross Mountains, Poland

Acta Palaeontologica Polonica
We report the first occurrence of trace fossils in placoderm bones from the Upper Devonian of the Holy Cross Mountains. A taxonomic analysis of three ichnogenera revealed the earliest evidence of Sulculites (ie., Sulculites bellus), characterised by ...

Upper Devonian mercury record from North America and its implications for the Frasnian–Famennian mass extinction

, 2021
The Frasnian–Famennian biotic crisis (~372 Ma) was one of the “big five” mass extinction events in the Phanerozoic. This event was associated with dramatic climatic and oceanographic perturbations, including oceanic anoxia, global cooling, sea-level ...
