Bathynotus: A key trilobite taxon for global stratigraphic boundary correlation between Cambrian Series 2 and Cambrian Series 3

The Cambrian trilobite Bathynotus is a special morphology of Redlichiid,which is characterized by a wider thorax axis and an 11th macropleural segment bearing a long,backwardly directed spine.Additionally,its 12th and 13th pleural segments are narrow and they terminate at a fulcrum where they fuse together and to the posterior edge of the long macropleural spine.The genus is widely distributed,occurring in North America,Siberia,the Altay-Sayan fold belt of Russia,South China,the Tarim Basin of China,and Australia.It occurs primarily in deposits of the upper part of the continental slope,at the transition between stable platform settings and subsiding margins of the late Early Cambrian.Here,we recognize three species of Bathynotus from China,including B.holopygus which is widespread around the world.Although six species of Bathynotus have been reported from Siberia and the Altay-Sayan fold belt area of Russia,data presented here suggest that only three of these species are valid.Bathynotus exhibits a short geological range,with its first occurrence late in the unnamed Cambrian Series 2 and the last appearance datum of Bathynotus at the boundary of Cambrian Series 2 and Cambrian Series 3.The late appearance datum (LAD) of Bathynotus provides an important global stratigraphic marker of the boundary between Cambrian Series 2 and Cambrian Series 3.

Aspects of Romanian Early-Middle Jurassic palaeobotany and palynology. Part VII. Successions and floras

The Jurassic floras of Romania occur in the Carpathian Mountains and in Dobrogea (Eastern Romania). In the South Carpathians, diverse and well preserved floras have been recorded since the middle of the 19th Century in the Resita, Sirinia, Presacina, CernaJiu, Holbav and Cristian Basins. The ages of these floras range between Hettangian and Sinemurian, with representatives belonging to Bryophytes, Pteridophytes and Gymnosperms. Excellent preservation and diversity were recorded in Anina, in the central area of the Resita Basin, a possible fossile-Lagerst?tte locality. The 3D collecting opportunities due to underground coal mining permitted detailed phytostratigraphical studies. These studies showed a floral change at the Hettangian-Sinemurian boundary, related to climate change. The Jurassic coal basins of the South Carpathians show both intramontainous and paralic features. The Resita Basin is a typical intramountainous depression basin, while the other basins are influenced by the marine realm. From a paleogeographical point of view, the Romanian Early and Middle Jurassic floras occurred on the northern frame of the Tethys realm, floristic features indicating the Eurosinian Province. One of the closest floras in terms of floristic similarities is the Iranian Early Jurassic flora. In the Apuseni Mountains, the HettangianSinemurian flora is less well-preserved and diverse than those of the South Carpathians. The Middle Jurassic flora of Romania is confined to Dobrogea (Eastern Romania), where a bennettite-dominated assemblage with low diversity and preservation was recorded.
