EN The most commonly used Lower and Middle Devonian conodont zonations that some times have been presented as standard zonations are evaluated. The author questions whether the Frasnian standard conodont zonation based on a phylogenetic succession of species belonging to the pelagicgenera Mesotaxis, Pa[...]

EN A high-resolution correlation of ten upper Givetian-Frasnian sections spread over the differ ent facies environments of the Eastern Anti-Atlas (Morocco) is established using graphic correlation. The mea sured strati graphic ranges of eighty-five cono dont taxa have been as sem bled into a chronostra[...]

EN Multi-stage development of carbonate buildups has been recognised in the Bol'shaya Nadota Carbonate Complex, in the vicinity of the town of Inta (Subpolar Urals). The growth of typical stromatoporoid-coral bioherms, characteristic of the Middle-Late Devonian stage, was terminated by the appearance o[...]

EN A formal Devonian chitinozoan biozonation for western Gondwana is proposed. This palaeogeographic province corresponds to South America, and was located in medium to high latitudes during the Devonian. Devonian chitinozoans are known from northern Argentina, Bolivia, Brazil and eastern Paraguay. Alt[...]

EN Numerous horizons of carbonates changed by karstic and soil-forming processes have been recognised in upper part of the Frasnian carbonate succession in southern part of the Holy Cross Mts. These layers are included in peritidal cyclothems, characterised by mostly deepening upward pattern, similarly[...]

EN The stratigraphical distribution of vertebrate remains in the standard section of the Upper Devonian of October Revolution Island of the Severnaya Zemlya archipelago has been studied. Fossil fish and agnathans were collected in 1978 and 1979 from the outcrops of the Matusevich, Vavilov and Malyutka [...]

EN Specimens of the Late Devonian ammonoid species Erfoudites rugosus sp. nov. from the Rhenish Massif of Germany show an additional wrinkled structure that covers the body chamber ornament. The pattern closely resembles the dorsal wrinkle layer known from many ammonoids; the course af the wrinkles is [...]

EN Five sections from the Kielce Region of the Holy Cross Mountains and one core from a borehole drilled in the nearby western Mesozoic Margin reveal the best recognized beds from the Devonian/Carboniferous boundary interval. In four sections: Ruda Strawczyńska, Bolechowice IG 1, Zaręby IG 2 and Kowala[...]

EN During the Devonian, the eastern Anti-Atlas formed a part of the northwestern continental margin of Gondwana which was a mid-latitudinal (30-40 stopni S), temperate-water carbonate province. In the Mader region, ten carbonate mounds (one reef-mound and nine mud-mounds), distributed over five discret[...]

EN The Givetian and Frasnian conodont suc cession investigated in the Compte section (Spanish Pyrenees) is subdivided into nine Givetian standard conodont zones and two Frasnian zones (MN zones). This succession allows precise identifcation of the lower/middle Givetian, middle/upper Givetian and of t[...]

EN Evolution of the Pomeranian Basin (NW Poland) dur ing the Devonian saw the development of a characteristic siliciclastic and mixed siliciclastic-carbonate marginal marine-to-open marine carbonate sedimentary succession. This was controlled via proximity of the land areas representing uplifted parts[...]

EN The results of excavation works aimed at exposing the pre-Late Devonian unconformity in the vicinity of Kłodzko (Middle Sudetes, NE Bohemian Massif) are reported. The unconformity, first described by Bederke in 1924, provides important constraints on the timing of the exhumation of metamorphic compl[...]

EN A combination of methods from cladistics and stratophenetic analyses is used for a reconstruction of Early and Middle Devonian ammonoid phylogeny. The analyses are based mainly on principal characters such as conch geometry (coiling form, whorl expansion rate, whorl cross-section shape), septal geom[...]

EN Stromatoporoid skeletons from polished slabs of stromatoporoid- and coral-bearing limestones of the Upper Devonian Kowala Formation from the Holy Cross Mountains in Central Poland have been measured using a classic parameterization method, introduced by KERSHAW & RIDING (1978) and improved by KERSHA[...]

EN Living corals are remarkably broad in their thermal and bathymetric ranges. But corals that could tolerate abnormally high temperatures (higher than 40 C) are unknown both in the living communities and in the fossil record. Here we report the discovery of small thermophilic rugose corals in the Devo[...]

EN The first occurrence of the conodont Ancyrodella rotundiloba has been used extensively for correlating the Middle-Up per Devonian (Givetian-Frasnian) boundary in sections worldwide despite many arguments as to its precise taxonomic definition. These arguments are summarised herein and three ontogene[...]
