Abstract: 

This paper presents the results of taxonomic and biostratigraphic investigations on the Upper Toarcian ammonite genera Grammoceras, Pseudogrammoceras and Podagrosites, derived from the Ozirovo Formation in the Western and Central Balkan Mountains (Bulgaria). It is based on the re-examination of almost all of old Bulgarian material, collected from the middle of the 40s to the end of 60s of last century, as well as on the ammonites obtained by the author in some new localities in course of the last few years. 23 taxa of species group of these three genera are described and figured. The Grammoceras thouarsensePseudogrammoceras mediterraneum and Pseudogrammoceras fallaciosum ammonite Biozones are described and compared to their contemporaneous equivalents of the zonal scheme proposed for the Toarcian by French Jurassic Working Group (Elmi, Rulleau, Gabilly & Mouterde, 1997).

Л. Методиев. Grammoceras, Pseudogrammoceras и Podagrosites (Grammoceratinae, Ammonitina) с верхнего тоара Балканского региона (Болгария). Таксономия и биостратиграфия. Настоящая работа посвящена таксономическому и биостратиграфическому изучению верхнетоарских аммонитных родов Grammoceras, Pseudogrammoceras и Podagrosites, происходящих с отложении Озировской свиты Западного и Центрального Балкана Болгарии. Материалом для данной работы послужила коллекция аммонитов, собранная с срединны 40-ых до конца 60-ых годов прошлого столетия, а также екземпляры коллекционированные автора в течение последных нескольков лет. Описаны и фигурираны были 23 таксоны видовой группы с исследованых аммонитных родов. Аммонитные биозоны Grammoceras thouarsense, Pseudogrammoceras mediterraneum и Pseudogrammoceras fallaciosum были характеризированы и сопоставлены с их едновозрастовых еквивалентов зональной схемы Тоарского яруса Французкой Работной Группы по Юрской системы (Elmi, Rulleau, Gabilly & Mouterde, 1997).
