“…Consequently, it is unlikely to find Cytherellina subclara in the late Famennian because the duration of this species would then be at least 30 Ma. The taxa duration of ostracod species is out of the scope of this paper: the reader is refered to Forel et al (2021) for further discussion. It is here considered as Cytherellina caerulea sp.…”

The impact of the late Devonian Hangenberg Event on ostracods is quantified for the first time from newly acquired data from the Blue Snake section, Guizhou Province, South China. Ninety–eight species belonging to 31 genera are identified and figured. Four new species are described: Clavofabella? lanshella sp. nov., Sansabella gelaohensis sp. nov., Cytherellina caerulea sp. nov., Sulcella baisuzhena sp. nov. The ostracod associations from the Blue Snake section document a significant drop in specific diversity as well as major changes in taxonomic composition through the Hangenberg Event. We here report the reduction of the proportion of Palaeocopida and the increase in that of Podocopida between the latest Famennian and the Tournaisian. The specific extinction and renewal rates are estimated at 44% and 62%, respectively. The main factor of the post–crisis renewal of ostracod faunas in the Blue Snake section appears to be the progressive diversification of the family Bairdiidae and was probably related to palaeoenvironmental changes. The characteristics of associations point to an increase of the water depth over the studied area, from a near–shore shallow environment during the latest Famennian to a deeper and more open offshore environment during the Tournaisian.

“…For these reasons ostracods are useful in biostratigraphy and are valuable archive to reconstruct past environmental and climatic changes (Holmes & De Deckker, 2012; Horne et al., 2012; Marchegiano et al., 2018, 2019, 2020; Mischke et al., 2010; Pérez et al., 2013; Ruiz et al., 2013; Schwalb et al., 2002; Von Grafenstein et al., 1999). The main advantage of applying ∆ 47 technique on ostracods relies on their stable low‐Mg calcite shell mineralogy, which usually are well preserved in the fossil record (e.g., Bajpai et al., 2013; Forel et al., 2021; Janz, 2000), compared to aragonitic mollusks. Also, through the analyses of ostracod assemblage, it is possible to establish if shells were autochthonous or allochthonous (Zacarías et al., 2019).…”

This study presents a methodological advancement in the field of clumped‐isotope (∆47) thermometry, specifically tailored for application to freshwater ostracods. The novel ostracod clumped isotope approach enables quantitative temperature and hydrological reconstruction in lacustrine records. The relationship between ∆47 and the temperature at which ostracod shell mineralized is determined by measuring ∆47 on different species grown under controlled temperatures, ranging from 4 ± 0.8 to 23 ± 0.5ºC. The excellent agreement between the presented ∆47 ostracod data and the monitored temperatures confirms that ∆47 can be applied to ostracod shells and that a vital effect is absent outside the uncertainty of measurements. Results are consistent with the carbonate clumped‐isotope unified calibration (Anderson et al., 2021, https://doi.org/10.1029/2020gl092069), therefore, an ostracod‐specific calibration is not needed. The ostracod clumped‐isotope thermometer represents a powerful tool for terrestrial paleoclimate studies all around the world, as lakes and ostracods are found in all climatic belts.
