Faune marine du terrain houiller de la Belgique. Répartition stratigraphique dans la région de Charleroi et de la Basse-Sambre
... The same beds contain Fayettevillea darwenensis, Eumorphoceras bisulcatum and E. beta (Bisat 1932;Moore 1946;Hodson 1957;. This subzone is also recognized in the Rhenish Mountains (Schmidt 1934;Patteisky 1959) and Belgium (Dorlodot and Delépine 1930;Demanet 1941). Based on the presence of Nuculoceras and later Cravenoceratoides, the E 2d Subzone correlates with the Delepinoceras bressoni Zone of the South Urals and Western Tien Shan. ...
... There are multiple ammonoid occurrences in this genozone, e.g. I. subglobosum (see Bouckaert 1961), and H. beyrichianum (see Dorlodot and Delépine 1930;Demanet 1941). In thick successions, Isohomoceras usually precedes Homoceras (British Isles, Belgium, Zilair Synclinorium in the South Urals, Aksu Section in SW Gissar, Uzbekistan), while in more condensed sections these genera are found together (USA, Western Kazakhstan). ...
... The B. gracilis Zone was also recognized in Berwinne locality 748, where B. gracile was found in Bed 2 (Niveau I), 0.3 m above the band with R. reticulatum, 0.96 m above the last occurrence of Reticuloceras nodosum in Bed 8 (Niveau IV) and 2.57 m above the first appearance of R. nodosum. Bilinguites gracilis as well as B. bilinguis were reported from the Assise d'Andenne, from Charbonnages de Forte-Taille, Baulet in Charbonnage d'Envoz, Java-Querschlag and other localities (Dorlodot and Delépine 1930;Demanet 1941). ...
Considerable progress has been made by international teams in refining the traditional ammonoid zonation that remains the backbone of Carboniferous stratigraphy. The Carboniferous ammonoid genozones, with a few gaps, are now recognized throughout the entire system in most successions worldwide. Refined collecting and documentation of occurrences in Western Europe, North Africa, the Urals, China, and North America, aimed to establish the first evolutionary occurrences, and facilitated correlation with foraminiferal and conodont scales for most of the Carboniferous. From ten to eleven ammonoid genozones are now recognized in the Mississippian, and eight to nine genozones in the Pennsylvanian. Of these, the established lower boundaries of the subsystems are reasonably well correlated with the ammonoid zonation, whereas correlations with the ratified foraminiferal-based lower boundary of the Viséan and other stage boundaries, currently under discussion, need further research. Future success in the ammonoid geochronology will also depend on accurate identification and re-illustration of the type material, including material described by pioneers of ammonoid biostratigraphy.
... The paleogeographical separation of shelf areas in the Viséan was maintained during the Serpukhovian, thus discrete stratigraphical schemes had to be proposed for the various regions (compare Korn and De Baets 2015). The principal subdivision was developed by British researchers in the first half of the twentieth Century (Bisat 1924Bisat , 1950 Bisat and Hudson 1943; Hudson 1945) and adopted by workers on time-equivalent successions in other parts of Europe such as Ireland (Hodson 1957; Yates 1962), South Portugal (Korn 1997), the Netherlands (Dorsman 1945 ), Belgium (Dorlodot and Delépine 1930; Demanet 1938 Demanet , 1941 Demanet , 1943), northern France (Chalard 1960), the Rhenish Mountains (Schmidt 1934; Patteisky 1959; Horn 1960; Korn and Horn 1997b), North Moravia (Patteisky 1936), the Lublin Coal Basin of Poland (Bojkowski 1979), the Moroccan Meseta (Delépine 1941) and the Donetz Basin (Popov 1979 ). The stratigraphical subdivision of the sediments in these regions is mainly based on girtyoceratid, homoceratid, reticuloceratid and gastrioceratid ammonoids (Fig. 12.8). ...
The time interval between the Emsian (Early Devonian) and the end of the Permian is characterized by the rapid evolution of the Ammonoidea, and this evolution is reflected by the establishment of a detailed biostratigraphical scheme. Ammonoids are, together with the conodonts, the most important stratigraphical tools for this interval. The present time resolution in terms of ammonoid biostratigraphy is highest in the Devonian (one zone has a mean of 0.9 Ma) and in the Carboniferous (about 1 Ma), while the subdivision of the Permian is much coarser (about 2.5 Ma per ammonoid zone on average).
... The species composition of the ammonoid assemblages of the Verkhnyaya Kardailovka Section is typical of the South Urals, but is different from the assemblages of Western Europe (Bisat 1924;1928;1930;1932;Dorlodot and Delépine 1930;Delépine 1943;Moore 1946;Currie 1954;Horn 1960;Kullmann 1961;Yates 1962;Wagner-Gentis 1963;Ruzhencev and Bogoslovskaya 1971;Riley 1987;Korn 1988;1997;Tisley 2002, Kullmann et al. 2008 and others), North Africa (Delépine and Menchikoff 1937;Delépine, 1941;Korn et al. 1999;2006, and others) and North America (Miller and Furnish 1940;Miller and Youngquist 1948;Miller et al. 1952;Gordon 1965;McCaleb et al. 1964;Manger 1979;Saunders 1973;Saunders et al. 1977;Rambottom and Saunders 1989;Meeks et al. 1997;Meeks and Manger 1999;Saunders and Work 1999;Titus 1999Titus , 2000Titus and Manger 2001, and others), although the generic composition is similar. ...
A uniquely complete carbonate sequence spanning a large portion of the Viséan and the entire Serpukhovian is exposed on the Ural River, opposite the village of Verkhnyaya Kardailovka (South Urals, Bashkortostan, Russia). The Upper Viséan and Serpukhovian beds in this section are composed of deep-water carbonates containing ammonoids, conodonts, ostracodes and foraminifers. The section is well-sampled, measured, its lithology is now described, and a sedimentary environment near the seaward end of a carbonate platform and deep shelf is suggested. Abundant fossils allow the recognition of four successive ammonoid and four successive conodont zones, which allow reliable correlations of the regional Serpukhovian stages outside the South Urals, although the type section of the Serpukhovian in the Moscow Basin is in the shallow-water facies. The base of the Serpukhovian in the Moscow Basin and in the South Urals is defined by the first appearance datum (FAD) of the conodont Lochriea ziegleri. This level coincides with the base of the Kosogorskian in the Urals, correlates with the entry of the foraminifer "Millerella" tortula near the base of the Tarusian in the Moscow Basin and is close to the earliest occurrences of Dombarites paratectus and Cravenoceras at the base of the Uralopronorites-Cravenoceras Genozone and of the latter genus at the base of the British E1 Zone. Because of its accessibility, abundant fossils, and its well studied lithology, the Verkhnyaya Kardailovka Section is an excellent candidate for the GSSP of the Viséan-Serpukhovian boundary.
The ammonoid genera Cancelloceras and Gastrioceras are important index fossils for the subdivision of mid-Bashkirian strata; both are represented by species in the Qilian Mountain region of Gansu and Ningxia (North China). In the Xiaoyuchuan section, four successive ammonoid assemblages were recorded, in ascending order with Cancelloceras pachygyrum, Cancelloceras zhoungweiense, Gastrioceras stenumbilicatum and Gastrioceras wongi. These species are revised here, together with a description of the new species Homoceratoides wangchengi Korn and Wang, n. sp.
In northern France and Belgium; Palaeozoic sarcopterygians are represented by actinistians (six species of Rhabdoderma ranging from the Visean to Westphalian D); onychodontids (remains of Onychodus from the Givetian to the middle Frasnian); dipnoans (four genera including 11 species ranging from the Givetian to the Famennian); porolepiforms (two genera restricted to the Famennian of Belgium); rhizodont (Spodichthys from the Frasnian and Strepsodus sauroides ranging from Namurian A to Westphalian B); osteolepiforms (including osteolepidids; megalichthyids; rhizodopsids; and tristichopterids ranging from the Famennian to Westphalian D) and one tetrapod trackway (Westphalian C).
More than 61 chondrichthyan genera belonging to six families of Holocephali and 13 families of Elasmobranchi have been reported from the Frasnian to Westphalian D. Although very rare; acanthodians represent the oldest vertebrates reported from northern France and Belgium (uppermost Silurian). Actinopterygian taxa are relatively diversed in the studied area (more than 20 nominal species); they include mimiids (Famennian); stegotrachelids (Frasnian-Namurian A); osorioichthyids (Famennian); kentuckiids (Namurian A); acrolepidids (Namurian A; Westphalian A); rhadinichthyids (Viséan; Namurian C-Westphalian D); gonatodids (Viséan; Westphalian C-D); styracopterids (Viséan); canobiids (Famennian); platysomiids (Viséan; Westphalian A-B); amphicentrids (Westphalian B); and palaeoniscids (Famennian-Westphalian D).
