Morphological Specification Of Chinianella Scheympflugi Hofmann, 1994, A Late Jurassic (?Earliest Cretaceous) Dasycladalean Alga Of The Western Tethyan Domain, Felix Schlagintweit
Morphological Specification Of Chinianella Scheympflugi Hofmann, 1994, A Late Jurassic (?Earliest Cretaceous) Dasycladalean Alga Of The Western Tethyan Domain, Felix Schlagintweit
Studia UBB Geologia
The dasycladalean alga Chinianella? scheympflugi was described by Hofmann (1994) from the Tithonian of the Ernstbrunn Limestone of Lower Austria. This alga, so far unreported besides its type-locality, is reported from the Late Jurassic of Poland, the Northern Calcareous Alps of Austria, Crimea (Ukraine), and Greece (Parnassos Zone). Facies are well-agitated outer platform habitats (peri-reefal and back-reefal facies). The cylindrical thallus consists of three parts: a sterile Salpingoporella-like basal part (stalk), a fertile Chinianella-type main portion and a short sterile top part. The transition from the stalk to the main thallus portion is well marked and abrupt. The stratigraphic range …
New Data On Facies Development And Micropaleontology Of The Eastern Margin Of The Getic Carbonate Platform (South Carpathians, Romania): Case Study Of Mateiaş Limestone, Ioan I. Bucur, Daniela Beles, Emanoil Sasaran, Constantin Balica
New Data On Facies Development And Micropaleontology Of The Eastern Margin Of The Getic Carbonate Platform (South Carpathians, Romania): Case Study Of Mateiaş Limestone, Ioan I. Bucur, Daniela Beles, Emanoil Sasaran, Constantin Balica

Mateiaş Limestone represents a lithostratigraphic unit included in the Braşov Series, which is a component of the eastern end of the Getic Nappes’ cover (the Getic carbonate platform). The study of the Mateiaş Limestone in Hulei-Mateiaş-Măgura area has evidenced three main facies, and five microfacies types. The Kimmeridgian (possibly also Early Tithonian) age of the Mateiaş Limestone has been assigned based on a microfossil association identified in thin sections. The regional framework, as well as their sedimentological and micropaleontological features point to the deposition of these limestones on shelf margin and slope environments; the succession in the studied area corresponds …
Late Jurassic–Early Cretaceous Foraminifera From Štramberk-Type Limestones, Polish Outer Carpathians, Daria Ivanova, Boguslaw Kolodziej
Late Jurassic–Early Cretaceous Foraminifera From Štramberk-Type Limestones, Polish Outer Carpathians, Daria Ivanova, Boguslaw Kolodziej
Studia UBB Geologia
Foraminifera studies were carried out on the Štramberk-type limestones which occur as pebbles to small boulders (exotics) within the uppermost Jurassic–Palaeogene flysch deposits of the Polish Outer Carpathians. The studies were focused on foraminifera from (1) reef and peri-reef facies, and (2) lagoonal algal-foraminiferal facies. The paper deals with 34 species (including 8 in open nomenclature) representing 30 genera, 22 families, 14 superfamilies, 11 suborders, and 7 orders. A more precise age determination has been obtained for 30 exotics, representing a Tithonian (mostly) to Valanginian age. Foraminiferal assemblages from at least two exotics suggest a Valanginian age as indicated by …
