Lower Cretaceous Calcareous Agglutinated Foraminifera from Southern Dobrogea, Romania 363 Lower Cretaceous Calcareous Agglutinated Foraminifera from Southern Dobrogea, Romania. Part II. Early Cretaceous Cuneolinidae THEODOR NEAGU University of Bucharest, Laboratory of Paleontology, B-dul Nicolae BaIcescu 1, 70111 Bucharest, Romania ABSTRACT This paper presents a detailed study of the cuneoliniform group of foraminifera from the Lower Cretaceous (uppermost Berriasian to Lower Hauterivian) of Southern Dobrogea (Romania). Detailed study of the external morphology of the test and the inner structure in the primary chambers, enables new genera to be separated from the classical genus Cuneolina. Two new genera are described: Scythiolina n.gen. with the species S. flabellii n.sp., S. infundibuliformae n.sp., S. crumenaeformae n.sp., S. cuneata n.sp., S. filiformae n.sp., S. camposauri (Sartoni & Crescenti); and Histerolina n.gen. with the species: H. paxilliformae n.sp., H. ellipsiformae n.sp., H. pileiformae n.sp.

The microbiota is mostly composed of species of calcareous algae and foraminifera.

The main part of the succession consists of gray-bluish thin-bedded to massive orbitolinid limestones which are of Barremian-Albian age. The Lower Cretaceous sediments overlie the Rhaetian-Middle Jurassic Shemshak Group with an angular unconformity. At the base of the succession a several meter thick transgressive unit of dark red to brown conglomerates and sandstones is developed which corresponds stratigraphically to the Sangestan Formation (sensu Nabavi, 1972). The Lower Cretaceous is dis- conformably overlain by the Early Cenomanian Chrysalidina Limestone. According to the stratigraphic distribution of benthic foraminifera and associated fossil assemblages the Lower Cretaceous deposits of the studied sections are divided into four biozones. The angular unconformity at the base of the Lower Cretacecous unit is attributed to the Middle Cimmerian orogenic event. The Early Cretaceous transgression in the study area is considered to have occurred during the Neocomian? – Barremian.

One order (the Loftusiida Kaminski & Mikhalevich), five suborders (the Verneuilinina Mikhalevich & Kaminski, Nezzazatina, Loftusiina Kaminski & Mikhalevich, Biokovinina, and Orbitolinina), two families (the Syrianidae and the Debarinidae) and five subfamilies (the Polychasmininae, Praesphaerammininae Kaminski & Mikhalevich, Flatschkofeliinae, Gerochellinae and the Scythiolininae Neagu) are new. The classification is modified from the suprageneric scheme used by Loeblich & Tappan (1992), and incorporates all the new genera described up to and including the year 2000. The major differences from the Loeblich & Tappan classification are (1) the use of suborders within the hierarchical classification scheme (2) use of a modified Mikhalevich (1995) suprageneric scheme for the Astrorhizida (3) transfer of the Ammodiscacea to the Astrorhizida (4) restriction of the Lituolida to forms with simple wall structure (5) supression of the order Trochamminida, and (6) inclusion of the Carterinida within the Trochamminacea (7) use of the new order Loftusiida for forms with complex inner structures (8) broadening the definition of the Textulariida to include perforate forms that are initially uniserial or planispiral.

Die konische bis schwach flabelliforme Art zeichnet sich insbesondere durch eine massive Wand und Septen aus. Zusammen mit anderen Vor- kommen in der Plassen-Karbonatplattform kann die stratigraphische Reichweite vorläufig mit Ober-Tithonium bis Unter-Berriasium angegeben wer- den.

The microgranular/agglutinated imperforate larger foraminifera (ILF, chiefly “lituolids”) of Mesozoic shallow marine carbonate shelves are a polyphyletic group of K-strategists, ecologically homogeneous inhabitants of the photic zone (nutrient poor) and hosting symbionts as their larger porcelaneous recent equivalents.
