摘要

本文记录了北多布罗盖造山带古特提斯下三叠统沉积物中的牙形石动物群。Tulcea Veche采石场中暴露的研究地层的特征是存在多种软体动物，包括菊石提洛石决明子（Quenstedt）和双壳类蜕膜虫（Bittner）。该遗址也代表了腔棘鱼Dobrogeria aegyssensis Cavin&Grădinaru的典型位置。已恢复的牙形石动物群以Icriospathodus crassatus（Orchard）、Neospathotus robustiprinus赵和Orchard、Novispathodus abruptus（乌节）、Nv为标志。布罗克斯（乌节），女。aff。brochus（Orchard），Tr.ex gr.homeri（Bender），Tr.hungaricus（Kozur&Mostler。symmetricus（Orchard）和与Tr.symmetricus区相关的Triassopathodus sp。

SPATHIAN (LOWER TRIASSIC) CONODONTS FROM THE TIROLITES CASSIANUS BEDS IN PALEOTETHYS-ISSUED NORTH DOBROGEA OROGEN (ROMANIA)

The paper documents a conodont fauna from Lower Triassic deposits of Paleotethys-issued North Dobrogea Orogen. The studied strata exposed in the Tulcea Veche Quarry are characterized by the presence of diversified molluscs, including the ammonoid Tirolites cassianus (Quenstedt) and the bivalve Crittendenia decidens (Bittner). The site also represents the type locality of the coelacanth fish Dobrogeria aegyssensis Cavin & Grădinaru. The recovered conodont fauna is marked by Icriospathodus crassatus (Orchard), Neospathodus robustispinus Zhao & Orchard, Novispathodus abruptus (Orchard), Nv. brochus (Orchard), Nv. aff. brochus (Orchard), Tr. ex gr. homeri (Bender), Tr. hungaricus (Kozur & Mostler), Tr. ex gr. hungaricus (Kozur & Mostler), Tr. symmetricus (Orchard), Tr. aff. symmetricus (Orchard), and Triassospathodus sp. that is correlated with the Tr. symmetricus Zone.
