“…During the Devonian, many biocrises have been identified (May 1995;House 1985House , 1996. These crises are generally defined in bathyal settings, based on changes among pelagic faunas such as ammonoids and conodonts (Walliser 1996) but few or no extinction affecting the benthic faunas.…”

“…During the late Eifelian, the Kačák event (House 1985) is marked by faunal turnovers and by rapid facies changes, probably induced by a change of oxygenation in the water column in response to eustatic and/or temperatures variations (Chlupáč & Kukal 1986, DeSantis & Brett 2011. The Kačák event extended through the entire ensensis Zone directly below the Eifelian-Givetian boundary (House 1996, Walliser 1996, Schöne 1997.…”

“…The Kačák event can be separated into two distinct phases spread over about 200 kyr (Walliser 1996, Schöne 1997, DeSantis 2010, Ellwood et al 2011, Kido & Suttner 2011. The first phase -otomari event or rouvillei event or Ei 1 (in Walliser 1996) -corresponds to the base of the ensensis conodont Zone and is characterized by the onset of anoxic black shales in many localities.…”

“…The first phase -otomari event or rouvillei event or Ei 1 (in Walliser 1996) -corresponds to the base of the ensensis conodont Zone and is characterized by the onset of anoxic black shales in many localities. It is also coincident with the boundary between the kockelianus and ensensis conodont zones and is associated to the spread of the dacryoconarid Nowakia otomari and the goniatite Cabrieroceras crispiforme (= C. rouvillei = C. ple beiforme) (House 1985;Chlupáč & Kukal 1986, 1988Walliser 1996;Schöne 1997;DeSantis 2010;Ellwood et al 2011). The black shale was deposited during a rapid rise of the sea level that triggered the abrupt development of anoxic conditions in the basin (Chlupáč & Kukal 1988).…”

“…The black shale was deposited during a rapid rise of the sea level that triggered the abrupt development of anoxic conditions in the basin (Chlupáč & Kukal 1988). The second phase -Kačák event s.s. or Ei 2 (in Walliser 1996) -immediately before the Eifelian-Givetian boundary, is characterized by the end of the black shale deposition combined with numerous extinctions among goniatites (House 1996, Walliser 1996, Schöne 1997, DeSantis 2010, Ellwood et al 2011. Marshall et al (2007) suggested that a change in insolation could have triggered the event through an increase of temperature and consecutive stratification of oceanic water and development of anoxia transported towards the shelves by the correlative transgression (May 1995).…”

During the Devonian period, major continents/blocks were located in the southern hemisphere (e.g. Stampfli et al. 2002, 2013; Scotese 2014), with a major mountain range running on the northeastern margin of Laurussia to Gondwana: the Appalachian range (Fig. 1) (DeSantis 2010, Scotese 2014). This period of time is marked by one of the most significant modifications in palaeobiogeography with the precipitated end of the strong faunal endemism of the Emsian-Eifelian and the initiation of the Givetian-Frasnian cosmopolitanism (Oliver & Pedder 1979b). During the early Emsian to late Eifelian interval, three distinct faunal assemblages allow the definition of three different marine realms (Oliver & Pedder 1979a, 1979b, 1994; May 1995, 1997b), separated by various barriers. The Malvinokaffric Realm (MKR), located along the margins of Gondwana (Fig. 1), is relatively poor in corals and it is characterized by cold-water species (Oliver 1990;

Latest Devonian to earliest Carboniferous conodont and carbon isotope stratigraphy of a shallow‐water sequence in South China

et al. 2015

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.

The proposed Anthropocene Epoch/Series is underpinned by an extensive array of mid‐20^th century stratigraphic event signals

The extensive array of mid‐20th century stratigraphic event signals associated with the ‘Great Acceleration’ enables precise and unambiguous recognition of the Anthropocene as an epoch/series within the Geological Time Scale. A mid‐20th century inception is consistent with Earth System science analysis in which the Anthropocene term and concept arose, and would reflect the reality that our planet has sharply exited the range of natural variability characterizing the Holocene Epoch/Series, which the Anthropocene would therefore terminate. An alternative, recently proposed ‘geological event’ approach to the Anthropocene is primarily an interdisciplinary concept, encompassing historical and socio‐cultural processes and their global environmental impacts over a diachronous timeframe that extends back at least many millennia. Resembling more closely a geological episode than an event, it would decouple the Anthropocene from its chronostratigraphic delineation and association with an abrupt planetary perturbation; but separately defined and differently named it might be usefully complementary. We recommend a clear separation of epochs, events and episodes. An epoch is a formal subdivision of the Geological Time Scale, and its correlation may be assisted by one or more events; an event is usually, and particularly in the Quaternary, a brief incident or perturbation with a sedimentary expression; and an episode is a longer, internally complex time interval that may include several events and even extend across several epochs.
