SUMMARY The size of early ontogenetic shells (protoconchs) ancient benthic molluscs suggests that feeding larvae occurred at about 490 myr (approximately, transition from Cambrian to Ordovician). Most studied Ordovician protoconchs were smaller than ones, indicating eggs and hatchlings. This substitution nutritious reserve matter such as yolk by plankton an energy source for larvae. observed change represents the first direct empiric evidence a late switch planktotrophy in invertebrate It...
La Formación San Juan es la unidad terminal de una secuencia que comprende rocas carbonáticas depositadas desde el Cámbrico al Ordovícico temprano, predominantemente en ambiente plataforma somera. Se estudiaron los conodontes del perfil Niquivil, abarcan asociaciones Zona P. elegans hasta posiblemente Subzona Eoplacognathus? variabilis/Microzarkodina jlabellum, inferior A. variabilis las sucesiones baltoescandinavas, extendiéndose Arenigiano Inferior Superior. El material estudiado fue...
Tremadocian (Lower Ordovician) carbonate rocks were collected from the Xiangshuidong section in Hubei Province, South China, and analyzed for conodont biostratigraphy. A total of 24 species belonging to 16 genera recovered Nantsinkuan Fenhsiang formations. Three zones are recognized based on this material, i.e., Rossodus manitouensis Zone, Colaptoconus quadraplicatus - Paltodus pristinus Assemblage deltifer ascending order. biostratigraphic gap, corresponding Cordylodus lindstromi angulatus...
A total of 239 isotope samples are used for establishing the δ13C chemostratigraphy in upper Middle Ordovician to Lower Silurian succession approximately 70 m long Borenshult drillcore. The study interval starts Darriwilian Furudal Limestone and ends Rhuddanian Motala Formation. Four named excursions recognized 3–4 formations, namely Guttenberg carbon excursion (GICE) lower-middle Freberga Formation, Kope (Rakvere) uppermost Formation possibly Slandrom Whitewater (Moe) Member Jonstorp...
Based on δ 13 C data from two drillcores recovered the Siljan district, we present a first continuous carbon isotope record of upper Tremadocian-lower Katian limestone succession central Sweden.New names for some isotopic excursions Cambrian-Ordovician boundary through basal Darriwilian are introduced.The Mora 001 core western part impact structure ranges Lower-Middle Ordovician, whereas Solberga 1 its eastern Middle-lower Upper Ordovician.Upper Tremadocian and Floian units extremely...
Abstract One of the few and most complete records MDICE (Middle Darriwilian Isotope Carbon Excursion) is herein documented from Baltoscandia. Based on a core section penetrating condensed Lower–Middle Ordovician succession (~46 m) island Öland, southeastern Sweden, we provide an integrated scheme for carbon isotope chemostratigraphy (313 samples) conodont biostratigraphy (29 this period. The carbonate in Tingskullen 12 zones 6 subzones, including Oepikodus evae, Trapezognathus diprion,...
The Fezouata Lagerstätte, discovered in the Lower Ordovician rocks of Morocco, is a Konservat-Lagerstätte prime scientific importance. It provides access not only to 'shelly' (skeletonized) part its fossil assemblages, but also non-biomineralized lightly sclerotized organisms and exceptionally preserved soft tissues complex ecosystem, mixing elements both 'Cambrian Explosion' 'Great Biodiversification Event' (GOBE). Lagerstätte occurs at different intervals Shale, formation ranging from...
Abstract A recent drilling at Borenshult near Motala resulted in discovery of the stratigraphically most complete succession through upper Darriwilian–Rhuddanian interval known Östergötland. The approximately 70 m long drillcore is subdivided into eight formations, oldest being late Darriwilian Furudal Limestone and youngest Rhuddanian Formation. Conodonts are used for a detailed biostratigraphic classification three subzones Pygodus serra Zone, two anserinus Amorphognathus tvaerensis Zone....
Based on the Tingskullen drillcore, we present first continuous carbon isotope stratigraphy from Lower–Middle Ordovician "orthoceratite limestone" of Öland, Sweden. The extremely condensed Tremadocian and Floian stages include large gaps as well Ceratopyge Regressive Event widespread Evae transgression accompanied by prominent shifts in δ 13C record. Dapingian Darriwilian are characterised low sedimentation rates a relatively complete sedimentary A total 99 whole-rock samples were analysed...
Two new reflection seismic profiles over the Paleozoic successions of western part Siljan Ring impact structure show a contrasting signature. The more southerly c. 10 km long Mora profile reveals highly disturbed structure, with only few kilometers relatively horizontally layered structures observed. However, interpretations refracted arrivals in data, that can be correlated to reflections, indicate Silurian clastic rocks about 200 m thick central profile. Weak reflections from 600 depth...
New drill cores from the largest known impact structure in Europe, relict of Siljan meteorite crater, provide new possibilities to reconstruct Early Palaeozoic marine environments and ecosystems, document changes sedimentary facies, sea level palaeoclimate Baltoscandia. The crater is an important target project "Concentric Impact Structures Palaeozoic" within framework "Swedish Deep Drilling Program". Two core sections, Mora 001 Solberga 1, have been analysed. successions these sections...
