Fourteen coralline algal species (Corallinales, Sporolithales) from Early Langhian (Lower Badenian) red-algal limestones of the Carpathian Foredeep (Czech Republic) are described: Sporolithon lvovicum (Maslov) Bassi et al., Lithothamnion roveretoi Airoldi, moretii Lemoine, ?Lithothamnion sp. 1, 2, Mesophyllum alternans (Foslie) Cabioch & Mendoza, M. cf. erubescens printzianum Woelkerling Harvey, curtum Phymatolithon sp., Lithophyllum Hydrolithon lemoinei (Miranda) Aguirre al. and Spongites...
Two shallow boreholes were drilled in the Badenian (Langhian) parastratotype at Židlochovice (Carpathian Foredeep, NN5 Zone, Czech Republic). Their profiles (26 m of sediment) studied comprehensively (sedimentology, geochemistry, gamma-spectrometry, paleontology – calcareous nannoplankton, red algae, palynology, Foraminifera, Bryozoa, Brachiopoda, Ostracoda, Mollusca, Teleostei and Elasmobranchii). The sedimentary succesion was biostratigraphically correlated with Zone (14.9 –13.9 Ma),...
Colonization by marine organisms such as foraminifers, molluscs, bryozoans, brachiopods and red algae during the Middle Miocene (Early Badenian) transgression near Přemyslovice (Carpathian Foredeep) was initially affected a cool water current of unclear origin. However, shortly afterwards, fallout volcanic material caused total termination biota. After this catastrophe, biota started recolonize area. The succeeding association, adopted to warm-water input, is characteristic...
A high diversity of larger benthic foraminifera (LBF) fauna is recognized from the Ilerdian-Cuisian sedimentary succession for first time Birjand region, Sistan Suture Zone eastern Iran. These are described in accordance with standard shallow zonation, placing considerable emphasis on biostratigraphic and microfacies analysis implications. Four zones (SBZ8 SBZ10-12) have been designated LBF horizons comprising index zonal markers such as Alveolina elliptica nuttalli (Davies), A. decipiens...
The examination of fossil Lithothamnion specimens ranging in age from the Early Miocene to Pleistocene revealed occurrence multiporate conceptacle chambers pitted with depressions.This is diagnostic feature crispatum, a cosmopolitan hapalidiacean wide depth range modern oceans.The comparison microscopic anatomy both and L. crispatum confirmed that they are conspecific.Therefore, this species has long stratigraphic distribution starting at least 20 My ago, without significant morphological...
Dramatic tectonic and sea level changes of the Central Paratethys realm during Middle Miocene resulted in coastal seabed morphology affecting composition marine association distribution facies along coast. Three different episodes (marine-terrestrial-marine) environmental evolution are interpreted. A lower unit (Badenian; Lower Serravallian) reflects organodetrital sedimentation on around an algal bioherm. Low terrigenous input maërl typical rhodalgal carbonate factory type characterise top...
Coralline algae were widespread in shallow-water environments during the middle Miocene central Paratethys.Their distribution and diversity patterns are useful paleoenvironmental paleoclimatic studies providing that species identifications accurate robust.Taxonomy of fossil coralline was traditionally based on morphology bi/tetrasporophytes whereas taxonomy extant is additionally supported by characters can be observed remaining life cycle phases.Therefore, investigations such record also...
Despite their common occurrence, the potential of coralline algae is not yet fully exploited in paleoecological reconstructions.The reasons are mainly grounded taxonomic inconsistency caused by poor preservation or insufficient knowledge type material many species, and confusion derived from difficult recognition three-phased life cycle fossil record.Specimens newly collected samples, historical Schaleková's collection middle Miocene Paratethyan limestone were studied under optical scanning...
Molecular phylogenetic analyses discovered an unexpected biodiversity of coralline algae in modern oceans.This species richness is unlikely to be exclusive characteristic recent ecosystems.With the aim investigate fossil biodiversity, a large dataset western Mediterranean Miocene specimens, previously identified as Spongites fruticulosus (and synonymized taxa), have been revised based on current taxonomic framework.The analysis recognized two distinct groups.The first group includes...
