A new dasycladalean alga Salpingoporella? popgrigorei n. sp. was identified in Pădurea Craiului Mountains (northern Apuseni, Romania) in the Lower Aptian limestone of the Valea Bobdei Member. The new alga was found within the external platform coarse bioclastic facies with fragments of corals, sclerosponges, bivalves (including rudists), gastropods, echinoderms, brachiopods, and bryozoans. The micropaleontological assemblage consists of foraminifera,
Read moreThe relationship between algae and depositional environment was studied in a limestone succession of Berriasian–Valanginian age. Several depositional environments were recorded from shallow subtidal to intertidal and supratidal, with salinity ranging from normal marine to fresh and/or supersaline water. The algal assemblages consist mainly of dasycladaleans, rivulariacean-type cyanobacteria and charophytes. Nipponophycus (Bryopsydales) and Lithocodium-Bacinella

Read moreA rich and diverse association of dasyclad algae occurs in the Middle Triassic rocks cropping out in Guizhou Province, China, including Macroporella alpina, Macroporella dinarica, Diplopora annulata, Diplopora annulatissima, Diplopora sinica n. sp., Pseudodiplopora proba n. gen., n. comb., and Julpiaella subtilis n. gen., n. comb. Study of this assemblage offered the opportunity to discuss the complex taxonomy of Diplopora-like dasyclads. A review
Read moreAn assemblage of calpionellids and calcispheres identified in five lithostratigraphic units allows the identification of eight biozones in the upper Oxfordian-Hauterivian interval. Since the biozonation according to calpionellids has already been accurately defined by Pop (1974, 1989) for the Marila Limestones and Crivina Marls, the novelty of our approach resides mainly in the extension of this biozonation to the over- and underlying lithostratigraphic
Read moreUntil recently, in the western part of the South Carpathians Triassic deposits were only known south of the Nera River between Sasca Montană and Moldova Nouă, belonging to the Sasca-Gornjak structural unit (Săndulescu 1975). Core analysis of a borehole drilled NE of Oravita (Brădisorul de Jos) led to the identification of a Triassic formation of the same type and age (Early-Middle Triassic) about 20 km further northerly than previously known.
