Palæozoic comprising the Cambrian, Silurian, Devonian, Carboniferous, and Permian species, with supplementary appendix brought down to the end of Abstract The abundances of nearly 40 elements, Ir included, have been measured using radio‐chemical and instrumental neutron activation analysis (RNAA and INAA) across a Devonian / Carboniferous (D / C) boundary section at Huangmao, Guangxi, China. The Ir anomaly has been found in the D / C boundary bed. Its peak value is ppt, richer by a factor of 12 than that in the underlying strata.

The global events gave little influence on the conodont diversity except for the Frasnian/Famennian (about 70% conodont species became extinct) and Devonian/Carboniferous extinction events.

Abstract. The discussion regarding where the Devonian–Carboniferous boundary (DCB) should be placed has a long tradition. The current boundary criterion and the GSSP at La Serre have long been criticised, and research work during the last two decades has highlighted several by: 2.
Abstract The Bruncu Bullai section, located in SE Sardinia, exposes limestones from the styriacus Zone (upper Famennian) to the Upper duplicata Zone (Tournaisian), but the Upper praesulcata Zone is not documented; at the Devonian/Carboniferous boundary a black shales level, equivalent to the Hangenberg Shales, is -six conodont taxa were recovered, three of which are here.
The Devonian (/ d ɪ ˈ v oʊ n. ən, d ə- d ɛ-/ dih-VOH-nee-ən, də- deh-) is a geologic period and system of the Paleozoic, spanning 60 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya.
It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation. A redefinition of the Devonian/Carboniferous boundary was reputed necessary, and in the International Commission on Stratigraphy established a working group with the goal to propose new criteria for defining the boundary and to find a new GSSP.
In this scenario, taxonomic revisions of conodont taxa with some.

Precise zonal dating of map units and revised dating of Antler orogenic events are provided by 38 conodont collections recorded in the Devonian/Carboniferous (D/C) Conodont Database and by small collections of conodonts embedded in siltstone and mudstone.

Bai, Z. Ning. Abstract. At the base of D-C boundary shale (Changshun Shale) most of the conodont species and the last tentaculite species became extinct.
The Late Devonian extinction was one of five major extinction events in the history of life on Earth. A major extinction, the Kellwasser event, occurred at the boundary that marks the beginning of the last phase of the Devonian period, the Famennian faunal stage (the Frasnian–Famennian boundary), about – million years ago.
Overall, 19% of all families and 50% of all genera became. The Carboniferous (/ ˌ k ɑːr. b ə ˈ n ɪ f. ər. ə s / KAHR-bə-NIF-ər-əs) is a geologic period and system that spans 60 million years from the end of the Devonian Period million years ago (), to the beginning of the Permian Period, Mya.
