Abstract This study presents the results of conodont biostratigraphy and microfacies analysis carried out on pelagic limestones Upper Triassic Dovško Section in Slovenia, which represents eastern part Slovenian Basin. The age section ranges from Lacian 1 to Alaunian 1. succession is predominantly characterized by representatives genus Ancyrogondolella . Transitional morphologies towards faunas ...

biostratigraphy of bahram formation succession, with 359.8 meter thickness, in the sardar section (north of kerman, central iran) is done in this study. bahram formation is mostly composed of limestones (with a lesser amount of sandstones), and conformably overlies the top sandstone beds of the padeha formation. but, the upper boundary with the hutk formation (late tounaisian) is disconformable...

Abstract The Norian represents the longest stage of Triassic, nevertheless, its precise subdivision is an unresolved matter. Conodonts might be useful in establishment accurate biozonation to avoid common scientific misinterpretations. Understanding evolutionary trends and morphological changes Ancyrogondolella lineage (genus descendant genera Epigondolella, Orchardella Mockina ) key importance...

Abstract A diverse labechiid stromatoporoid assemblage that includes 16 species in 8 genera was found the Upper Ordovician Xiazhen Formation (mid–late Katian) at Zhuzhai, Jiangxi Province of South China. The is characterized by a combination (1) North China provincial succeeding from their origination Darriwilian, including Pseudostylodictyon poshanense Ozaki, 1938, Labechia shanhsiensis Yabe a...

Abstract Quarries between Old Radnor and Presteigne, Welsh Borderlands, expose a Silurian nearshore succession, which onlaps rocky palaeotopography of the Neoproterozoic basement that had been uplifted along Church Stretton Fault Zone. The succession documents Aeronian to Sheinwoodian transgression an island or islands, with following sequence events: deposition shallow marine sandstones (Folly...
