Abstract
A rich diversified algal microbiota is described from the lowermost Valanginian limestone re?worked in the Upper Cretaceous elastics of the Metohija Cretaceous Unit (Mirdita Zone). Two new dasycladalean taxa are introduced: Zujovicella nov. gen. (type species Suppiluliumaella gocanini Radoicic, 1972) and Furcoporella vasilijesimici nov. sp. Microbiota of this bioclastic limestone (containing dominantly corals and other metazoan fragments) consists of algae, microbial epiliths, microproblematica, foraminifera, calcispongie and a few calpionellids of the Calpionellopsis Zone - Calpionellopsis oblonga (Cadisch), Remaniella cadischiana (Colom), Tinntinopsella carpathica (Murgeanu & Filipescu). Besides the new taxa dasycladales also associated are: Salpingoporella pygmaea (Gumbel), Salpingoporella sp., Gyroporella lukicae Sokac & Velic, Neomerinae and several indetermined taxa. Lithocodium aggregatum (Elliott), other encrusting Lithocodioidea and different microbial epiliths are an important component of this microbiota association. Foraminiferal assemblage consists of: Coscinophragma cf. C. cribrosum (Reuss), Mohlerina basiliensh (Mohler), Nautiloculina bronnimanni Arnaud-Vanneau & Peybernes, Neotrocholina valdensis Reichel, Neo-trocholina sp. Placopsilina sp., Protopeneroplis trochangulata Septfontaine, Trocholina alpina (Leupold), Trocholina delphinensis Arnaud-Vanneau, Boisseau & Darsac, Trocholina sp., lituolids, miliolids and other small benthic taxa. The analyzed lowermost Valanginian limestone originated from the topmost sequence of the Tithonian-Neocomian cycle which ended as a consequence of the Main Cimmerian Events, which occerred, as in the Vardar zone, after the lowermost Valanginian. Cretaceous cycle (Mirdita Crtaceous Unit) begins in the Hauterivian.
Highlights
Dasycladales Suppiluliumaella gocanini were described from Lower Valanginian limestone of the Orahovac region, Mirdita Zone (Fig. 1)
In the locality between the villages of Kravoserija and Boka this limestone was not found in situ (RADOI^I], 1972)
According to the Geological Map, the sheet Orahovac 1:100 000 (LON^AREVI], 1986), this area is covered by Upper Cretaceous carbonate clastics
Summary
Dasycladales Suppiluliumaella gocanini were described from Lower Valanginian limestone of the Orahovac region, Mirdita Zone (Fig. 1). In the locality between the villages of Kravoserija and Boka this limestone was not found in situ (RADOI^I], 1972). On the footpath between the mentioned villages, in a small outcrop of 2–2.5 m thick clastics, horizontally arranged cobblestones in the microbreccia bed were observed. One of them (cobble of cca 15×12 cm) was limestone with large (to 6 cm) coral and other metazoan fragments. On the surface of broken pieces, in the matrix between large fragments (bioclastic packstone-rudstone), some dasycladalean, different coating algal and microbial structures and foraminifera, were observed under a lens. The matrix between large metazoan fragments was used for thin slides (17), in some of which sections of Suppiluliumaella gocanini were found. The purpose of this paper was the revision of Suppiluliumaella gocanini, based on which Zujovicella nov. gen. is described, and the presentation rich associated biota including new dasycladalean species Furcoporella vasilijesimici
