Sažetak
Fossil brachiopods are recorded in the Middle Miocene (Langhian/Serravalian – Badenian) deposits in Northern Croatia, Medvednica Mt. near Zagreb, which paleogeographically belonged to the southwestern margin of the Central Paratethys (e.g., Rögl, 1998 ; Kováč et al., 2007 ; Piller et al., 2007 ; Sremac et al., 2022). The Badenian brachiopods from Northern Croatia are for the first time mentioned in Gorjanović-Kramberger (1908), and described by Kochansky (1944) and Kochansky-Devidé (1957). Since then, there have been no papers on the Badenian brachiopods from Croatia, except one unpublished Master Thesis by K. Bakrač (Sinković, 1994). Specimens described in the above-mentioned papers are today housed in the Croatian Natural History Museum and we decided to conduct their revision. A revision is based on the taxonomical review and biometry of the brachiopod specimens. In this paper we present preliminary results of this ongoing study. Brachiopods are represented by the class Rhynchonellata, with more than 700 specimens from the orders Rhynchonellida and Terebratulida, and the latter one prevails. Brachiopod assemblage from Northern Croatia shows similarity with the Miocene terebratulid record from Slovenia (e.g., Mikuž, 2011 and references therein), and also comprises the species Megerlia truncata (Linnaeus, 1767), common in the Miocene deposits of the Central Paratethys (e.g., Bitner & Dulai, 2004 and references therein). Several other brachiopod species, from the terebratulid family Megathyrididae, common in the Miocene of the Central Paratethys, e.g., Argyrotheca cuneata (Risso, 1826), Megathiris detruncata (Gmelin, 1790) and Joania cordata (Risso, 1826) (after e.g., Bitner & Dulai, 2004 and references therein ; Bitner et al., 2013 and references therein) are not recorded so far from the Miocene deposits of Northern Croatia. Study of the here presented brachiopod fauna could give further insight into the brachiopod biogeographical provinces and open marine connections in this area of the Central Paratethys during the Badenian Stage.
