The poorly known dasycladalean alga Cymopolia eochoristosporica Elliott, 1968 is reported for the first time from the upper part of the Tarbur Formation (Zagros Zone, SW Iran) assigned to a late Maastrichtian age. It was reported so far from the Maastrichtian Aruma Formation of Saudi Arabia (type-locality), the Maastrichtian Simsima Formation of Oman, and the Maastrichtian (e.g., Zongshan Formation)...
Pianella turgida, originally described from Cenomanian limestones of the external Dinarids, was subsequently transferred to the genus Salpingoporella. In the middle of the last century, Varma described the genus Morelletpora with Morelletpora nammalensis as type species from the Paleocene of India. Varma considered the new alga to be articulated, with club-shaped segments and only first order laterals...
Bačinella irregularis was described by Radoičić (Bull Serv Géol Géophys Rep Serbie 17:87–92, 1959) as an alga incertae sedis. Based on material from the Lower Aptian of the western Maestrat Basin (Spain), the genus Bačinella with its various species is revised; an emended diagnosis is given as well as a detailed description. Bačinella is interpreted as an organism that excavated complex branching...
Previously unreported dasycladaleans and one morpho-taxon of assumed algal origin are described from Upper Turonian to Santonian rocks of the Lower Gosau Subgroup (LGS) of the Northern Calcareous Alps. A taxonomic inventory of green-algal/benthic foraminiferal assemblages shows that assemblages of “pure” carbonate environments are more diverse than those of siliciclastic and mixed siliciclastic-carbonate...
Two new dasycladalean algae are described from the Gosau Group of the Northern Calcareous Alps in Austria. The tiny spicules of Acicularia? weisswasserensis n. sp. were found in foraminiferal wacke- to packstones associated with rudist limestones of the Weisswasser locality (Middle Coniacian), Lower Austria. The small globulous Terquemella? microsphaera n. sp. occurs in marls to marly limestones of...
Slightly curved calcitic plates with marginal pores recalling an aciculariacean alga are common in Late Tithonian reefal platform margin deposits of the Plassen Carbonate Platform of the Northern Calcareous Alps of Austria. Illustrated also from the Western Carpathians, these forms were assigned to the genus Acicularia, e.g., Acicularia elongata Carozzi. It is demonstrated that these algal parts are...
After Barattolo (Abstracts of the 5th international symposium on fossil algae, 1991) and Barattolo and Romano (Bollettino della Societa Paleontologica Italiana, 44(3): 237–254, 2005) emended the diagnosis of the genus Linoporella Steinmann to include species with three orders of laterals, algae included formerly in this genus but with only two orders of laterals remained in open nomenclature. Comparisons...
A characteristic microfacies of the Late Jurassic to Early Cretaceous allodapic Barmstein Limestone of the Northern Calcareous Alps are clasts of wackestones with numerous fragments of calcareous algae (“algal debris-facies”). According to dasycladale palaeocoenoses, several subtypes comprising different associations can be distinguished. One association is characterized by the debris of an unknown...
Summary In the florigemma-Bank Member of the Late Jurassic (Oxfordian) NW German Korallenoolith Formation moderately diverse assemblages of calcareous algae are present. The following taxa have been identified: “Porostromata”, Solenopora jurassica Brown, Solenopora helvetica Peterhans, Pycnoporidium lobatum Yabe and Toyama, Otternstella cf. lemmensis (Bernier), Salpingoporella? suentelensis n. sp...
A new Dasycladacean alga, Clypeina bavarica nov. sp., is described from Upper Tithonian limestonesof the Franconian Alb of South-Germany. The new species is characterized by a wide axial cavity and regularly spaced disk-like verticils with short club-shaped branches closed at tips. Branches and main axis display a micritic envelope. The limestones in which the new species occurs are interpreted as...
