Additionally, no covariation exists between δ 13 C carb and δ 18 O carb , and variation in the δ 13 C profile is similar to coeval δ 13 C carb records of Euroamerican sections (Buggisch et al ., ; Kumpan et al ., , ), indicating weak diagenetic alteration and the preservation of original marine carbonate δ 13 C signatures.…”

“…The general pattern of carbon isotopic changes for the Tournaisian successions has been well established on the basis of the analyses of whole‐rock limestones and well‐preserved brachiopods from the Euroamerican sections (Buggisch et al ., ). Across the Devonian–Carboniferous boundary, a minor negative shift of δ 13 C carb values has been recorded in Belgium, which postdates the peak values of the HICE at the end‐Devonian (Kumpan et al ., ). This negative shift has also been reported from DCB successions in the Graz Palaeozoic, southern Austria (Kaiser et al ., ).…”

To improve regional and intercontinental correlation of the uppermost Devonian–lowermost Carboniferous, we examined the conodont faunas and carbon isotopic records of the Tangbagou Formation in the Qilinzhai section, southern Guizhou, South China. The Tangbagou Formation is a succession of mixed carbonate–siliciclastic rocks that accumulated on a shallow‐water platform under normal marine conditions. Seven conodont zones for shallow‐water biofacies in South China, the Cl. gilwernensis–Cl. unicornis Zone, the Po. spicatus Zone, the Si. homosimplex Zone, the Si. sinensis Zone, the Si. eurylobata Zone, the Ps. multistriatus Zone and the Po. co. porcatus Zone in ascending order, are recognized in the Tangbagou Formation. Although apparently limited in its value for global correlation, this conodont zonation is more applicable to shallow‐water biofacies in South China. Carbonate samples have yielded carbon isotopic signatures consistent with those recorded in Euroamerica sections, in particular showing four distinct characteristics: (1) the peak values of Hangenberg Carbon Isotope Excursion (HICE) during the latest Devonian, (2) a minor positive shift (P1) in the Si. homosimplex Zone during the early Tournaisian, (3) a second minor positive shift (P2) in the Si. sinensis Zone and (4) the middle Tournaisian Carbon Isotope Excursion (TICE) in the middle part of the Tangbagou Formation. The similarity in peak values (~5.5‰) and magnitude of TICE for the Qilinzhai and Belgian sections indicates that the Euro‐asia δ13Ccarb trends may reflect the changes in global mean ocean δ13CDIC, rather than having been overprinted by local carbon cycling. Integration of conodont biostratigraphy and δ13C stratigraphy provides a powerful tool for stratigraphic correlation. Copyright © 2015 John Wiley & Sons, Ltd.

“…Even abiotic proxies such as geochemical data are rarely unambiguous (for instance, oxygen isotope data are affected by temperature of ambient seawater, salinity, and global ice volume) and their interpretation in deep time is subject to debate. The combination of several proxies may be a way to circumvent these problems (Zou et al, 2012;Kumpan et al, 2014;Finkenbinder et al, 2015;Matyja et al, 2015) and enrich our understanding of environmental variations in remote periods of time.…”

Abstract. Benthic foraminifera have been used as proxies for various paleoenvironmental variables such as food availability, carbon flux from surface waters, microhabitats, and indirectly water depth. Estimating assemblage composition based on morphotypes, as opposed to genus-or species-level identification, potentially loses important ecological information but opens the way to the study of ancient time periods. However, the ability to accurately constrain benthic foraminiferal assemblages has been questioned when the most abundant foraminifera are fragile agglutinated forms, particularly prone to fragmentation. Here we test an alternate method for accurately estimating the composition of fragmented assemblages. The "cumulated area per morphotype" method is assessed, i.e., the sum of the area of all tests or fragments of a given morphotype in a sample. The percentage of each morphotype is calculated as a portion of the total cumulated area. Percentages of different morphotypes based on counting and cumulated area methods are compared one by one and analyzed using principal component analyses, a co-inertia analysis, and Shannon diversity indices. Morphotype percentages are further compared to an estimate of water depth based on microfacies description. Percentages of the morphotypes are not related to water depth. In all cases, counting and cumulated area methods deliver highly similar results, suggesting that the less time-consuming traditional counting method may provide robust estimates of assemblages. The size of each morphotype may deliver paleobiological information, for instance regarding biomass, but should be considered carefully due to the pervasive issue of fragmentation.
