INTRODUCTION The Scaphopoda is a class of Mollusca, also known as the “tusk shells”. Their shell is tubular and generally curved, having open­ ings at both ends. Scaphopods are a cosmopolitan marine infau­ nal species, and live from the intertidal zones down to depths of more than 6000 m. Scaphopod species mostly burrow in sand or mud, with their head pointed downwards, and the narrow poste­ rior end of the shell protruding above the substratum (KNUD­ SEN, 1964; LAMPRELL & HEALY, 1998 and references therein; HABDIJA et al., 2011). Although the scaphopod systematics have been revised over a few decades, the time of their appearance is still a matter of debate, as are their phylogenetics, so they are considered to be a puzzling molluscan class. Two orders of scaphopods are known: Dentaliida and Gadilida, which differ both morphologi­ cally, in shell and foot form, and behaviourally, in different bur­ rowing activities (LAMPRELL & HEALY, 1998 and references therein; STEINER & KABAT, 2001, 2004). This paper focuses on the Badenian dentaliid species Fissi­ dentalium badense (PARTSCH in HÖRNES), recorded in the Mio cene deposits of the Paratethys, and widely distributed in Ba­ denian sediments of the Central Paratethys (e.g. BALDI, 1960; KOJUMDGIEVA & STRACHIMIROV, 1960; BALLUK, 1972; TITA, 2007; HARZHAUSER et al., 2011). Specimens of F. ba­ dense included here were collected from the Badenian sediments of the south and southwestern margin of the Central Paratethys (Croatia, Bosnia and Herzegovina and Serbia). The analyzed spe­ cimens are housed at the Natural History Museum Belgrade (NHMB) and Croatian Natural History Museum (CNHM). The first finding of F. badense from Bosnia and Herzegovina is pub­ lished here. 2. GEOLOGICAL SETTING The Central Paratethys extended from Bavaria to the Carpathian mountain chain (e.g. RÖGL 1998, 1999). Badenian sediments Fissidentalium badense (PARTSCH in HÖRNES, 1856) from the Badenian deposits of the south and southwestern margin of the Pannonian Basin System (Central Paratethys) Gordana Jovanović1 and Marija Bošnjak2 1 Natural History Museum Belgrade, Department of Paleontology, Division of Geology, Njegoševa 51, Belgrade, Serbia; (gordana.j@nhmbeo.rs) 2 Croatian Natural History Museum, Department of Geology and Paleontology, Demetrova 1, Zagreb, Croatia; (corresponding author: marija.bosnjak@hpm.hr) doi: 10.4154/gc.2016.20 Abstract The Badenian (Middle Miocene) Scaphopoda from the south and southwestern margin of the Pannonian Basin System (Central Paratethys) are poorly documented, and in published papers mostly presented by short lists of identified species. For the present study, 300 scaphopod speci- mens were examined with the focus on a singular species, Fissidentalium badense (PARTSCH in HÖRNES, 1856). This species is represented by 152 specimens housed in the Natural His- tory Museum Belgrade and the Croatian Natural History Museum in Zagreb. The most numero- us and the best preserved specimens of F. badense were collected at the Višnjica locality near Belgrade (Serbia), while the others originate from the vicinity of Zagreb (Croatia) and Ugljevik (Bosnia and Herzegovina). from the investigated area belong palaeogeographically to the south and southwestern margin of the Central Paratethys, and geotectonically to the Pannonian Basin System, surrounded by the Alps, Carpathians and Dinarides (Fig. 1) (e.g. RÖGL 1998, 1999; PAVELIĆ, 2001, 2002; PILLER et al., 2007). The beginning of the Badenian epoch is marked by a marine transgression, which flooded the areas behind the newly uplifted mountain chains (Paratethys) and was also prominent in the Medi­ terranean (Fig. 1) (RÖGL, 1998, 1999; KOVÁČ et al., 2007). Ac­ cording to numerous papers, the Badenian deposits of the south and southwestern margin of the Central Paratethys lie discorda­ ntly on the older Miocene, Mesozoic or even Palaeozoic deposits. The contact with basal rocks is in many places unclear or erosive or tectonic in character (e.g. ŠIKIĆ et al., 1978, 1979; BASCH, 1983a, b; VRABAC & MIHAJLOVIĆ, 1990; ANĐEL KOVIĆ et al., 1991; PAVELIĆ, 2001, 2002; SAVIĆ et al., 2005; PIKIJA, 2009). At the southern margin of Central Paratethys, F. badense is recorded in the Lower Badenian deposits of Serbia (wider Bel­ grade region) (PETKOVIĆ et al., 1976), in the assumed Lower to Middle Badenian of western Serbia (ŽUJOVIĆ, 1889; PAVLOVIĆ, 1903; STEVANOVIĆ, 1949; PETROVIĆ, 1967), and in the Lower Badenian (Upper Lagenidae zone) in northeastern Bosnia and Herzegovina (Bogutovo Selo) (VRABAC et al., 2013, 2014; PE­ ZELJ et al., 2013) (Fig. 1). In the area of the southwestern margin of the Central Paratethys, this species is present in the Miocene (probably Lower Badenian) marls of the wider Zagreb region (Med vednica Mt., Čučerje area) (KOCHANSKY, 1944, 1957; ĆORIĆ et al., 2009), and in the assumed Middle to Upper Bade­ nian deposits of the Samobor area (Vrhovčak locality, previously known as „Zaprešić Breg“ or „Zaprešić brijeg“) (ŠUKLJE, 1929; PAVLOVSKY, 1957, 1960; BAJRAKTAREVIĆ, 1978; VRSALJ KO, 2003; BAKRAČ et al., 2010). In the Badenian sediments of the Glinsko Pokuplje area, this species is found at one locality (PI­ LAR, 1873).

MATERIALS AND METHODS Three hundred scaphopod shells were examined, and 152 of them belong to the species Fissidentalium badense (PARTSCH in HÖRNES). All the analyzed specimens are damaged, mostly in the apex area, and the majority of specimens are preserved as shell fragments. NHMB specimens were collected at the Višnjica locality (wider area of Belgrade), and they are a part of the P. Pavlović collection, assembled in 1897 (90 specimens) and the P. Ste va­ nović collection, assembled in 1962 (40 specimens). Other spec­ imens come from the Loznica area in western Serbia (3 speci­ mens), and Bogutovo Selo near Ugljevik, Bosnia and Herzegovina (1 specimen). CNHM specimens originating from the wider Zagreb region are part of the „Marine Miocene fauna of the southern part of the Medvednica Mt.“ collection (10 specimens) and the „Miocene fauna of Zaprešić Breg near Samobor“ collection (5 specimens). Specimens from the third locality are part of the „Miocene and Pliocene fauna from the Glinsko Pokuplje area and Zrinjsko­ Dvorska valley“ collection (3 specimens). The site yielding the largest number of scaphopods is Višnjica (Fig. 1), with 280 specimens from clayey sediments, 130 among them belonging to F. badense (LUKOVIĆ, 1922; JOVA­ NOVIĆ & JOVANOVIĆ, 1998). This fossil fauna is the best pre­ served, and therefore chosen to be described here. Determination of species is based upon several papers (e.g. HÖRNES, 1856; SACCO, 1897; KOJUMDGIEVA & STRA­ CHIMIROV, 1960; PAVIA, 1991; STEINER & KABAT 2001, 2004). Parameters used in the determination are after STEINER (1999) and SILVA­FILHO et al. (2012) (Fig. 2). 4.

G eo lo gi a C ro at ic a Geologia Croatica 69/2198 between the primary ribs at various distances from the apex. The maximum number of inserted ribs near the posterior part of the shell does not exceed 30. The primary and secondary ribs at the posterior side of the shell are almost indistinguishable from each other with only minor differences. The species varies in number and thickness of the secondary ribs. Concave interrib spaces vary in width. Together with the radial ribs, fine and dense irregular growth lines (except in the apical area) characterize the shell sur­ face. The cross­section of both ends is subcircular. Remarks: Many authors studied the phylogeny and classifica­ tion of the scaphopods (e.g. REYNOLDS, 1997; REYNOLDS & AKOKO, 1999). Fissidentalium badense (PARTSCH in HÖRNES, 1856) was first recognized as Dentalium badense (HÖRNES, 1856), Entalis (SACCO, 1897) or Dentalium (Entalis) badensis (KOJUM­ DGIEVA & STRACHIMIROV, 1960). F. badense from the Višnjica locality, and presented here, fits the descriptions by PAVIA (1991). The species described in KOJUMDGIEVA & STRACHIMIROV (1960) has more secondary ribs (35), as do several specimens from Koritnica, Poland (BALLUK, 1972). STEINER & KABAT (2004) single out the subgenus Dentalium LINNAEUS 1758. In the re­ search of the taxonomy and ecology of the recent genus Fissiden­ talium (FISCHER), LAMPRELL & HEALY (1998) indicate the significance of the aperture, and the number and rib morphology that can contribute to the research of the fossil species. Geographic and stratigraphic distribution: Fissidenta­ lium badense (PARTSCH in HÖRNES, 1856) appears during the Burdigalian in the Mediterranean at the Torino Hills (SACCO, 1897), and in the Lower Miocene of the Paratethys (HARZHAUSER, 2002; HARZHAUSER et al., 2011). F. badense has a wide geogra­ phic distribution, and represents a species typical of the Middle Miocene of the Paratethys (e.g. KOJUMDGIEVA & STRACHI­ MIROV, 1960; PAVIA, 1991; HARZHAUSER et al., 2011). 5. DISCUSSION In the Badenian sediments of the south and southwestern margin of the Central Paratethys, the majority of scaphopod discoveries belong to the dentaliids. Here, we analyzed and revised Fissiden­ talium badense (PARTSCH in HÖRNES, 1856) specimens stored at the NHMB and CNHM. Given the number of the recorded dentaliids, Višnjica near Belgrade (Serbia) is the site yielding the largest number of specimens. At the Višnjica locality, scaphopods were discovered in the clayey sediments, known as the „Višnjica clays“ or the „clays with Pleurothoma“. This site was compared to the Badenian stratotype Baden­Sooss in Vienna (PAVLOVIĆ, 1903; LUKOVIĆ, 1922), which contains many specimens of F. badense. The stratigraphic position of the „Višnjica clays“ is not precisely determined. Based upon foraminifera, STEVANOVIĆ (1977) attributes it to the Mid­ dle Badenian, and GRUJIČIĆ (2010) specifies the zone with Spi­ ro rutilus carinatus (d’ORBIGNY). Sandstones containing rare fine­shelled pectens (Costelamussium sp.), Aequipecten macrotis (SOWERBY) and Aequipecten scabrella (LAMARCK) (LUKO­ VIĆ, 1922) cover the clay stratum. These pectinid species also occur in the Lower Badenian of Bukovac on the Fruška gora Mt. (JOVANOVIĆ, 2014), in the Grund Gaindorf formation in Aus­ tria (MANDIC & HARZHAUSER, 2003; MANDIC, 2004), and in the Lower Badenian (Lagenidae zone) sediments of Szokoly, Hungary (BALDI, 1960). The „Višnjica clays“ contain numerous scaphopod specimens: Fissidentalium badense (PARTSCH in HÖRNES), Gadilina jani HÖRNES, Dentalium sexangulum GMELIN, Dentalium (Antale) novemcostatum decemcostulata SACCO, Dentalium (Dentalium) michelottii HÖRNES and Fis­ sidentalium mutabile (DODERLEIN). In the Lower Badenian argillaceous marls of the wider Bel­ grade region, deep sea molluscs are very common: Neopycnodonte cochlear POLI, Lentipecten corneus denudatus (REUSS), Vaginella austriaca KITTL and Aturia aturi (BASTEROT) (PET KOVIĆ et al., 1976; JOVANOVIĆ, 2014). These findings, as well as the record of Parvamussium duodecimlamellatum (BRONN), indicate a Lower Badenian age (STUDENCKA et al., 1998; SELMECZI et al., 2012; JOVANOVIĆ, 2014). In the Miocene (probably Lower Badenian) marls of the wider Zagreb region („Čučerje“ develop­ ment on the Medvednica Mt.), the wider Belgrade region and Ug­ ljevik (Bogutovo Selo), together with dentaliids, scaphopods are accompanied by a pelagic fauna of nautilids (Aturia aturi (BAS­ TEROT), pteropods (Vaginella austriaca KITTL) and planktonic foraminifers (KOCHANSKY, 1944; STEVANOVIĆ, 1977, AVA­ NIĆ et al., 1995; JOVANOVIĆ, 2014). These known data, together with further detailed dentaliid analysis, can contribute to the re­ construction of the first Middle Miocene marine transgression in the south and southwestern margin of the Central Paratethys. All the published data and records suggest that F. badense mostly lived in muddy and muddy­sandy substrate at all the stud­ ied localities in Serbia, Bosnia and Herzegovina and Croatia. This species was widespread during the Lower Badenian, with fossil evidence from the clayey sediments of Austria (Baden­Sooss) (RÖGL et al., 2009), Romania (Lăpugiu de Sus) (TITA, 2007), Slovakia (BALLUK, 1972; HARZHAUSER et al., 2011), Hungary (BALDI, 1960) and Bulgaria (KOJUMDGIEVA & STRACHIMI­ ROV, 1960). The distribution of F. badense indicates the contem­ porary marine connections and migration routes. Due to the re­ corded and afore­mentioned findings, possible migration routes of F. badense to the area of Paratethys could be the southwestern („Transtethyan corridor“) and the northern marine passages (e.g. RÖGL, 1998; STUDENCKA et al., 1998; KOVÁČ et al., 2007). 6. CONCLUSIONS This paper presents the scaphopod species Fissidentalium ba dense (PARTSCH in HÖRNES, 1856) housed at the Natural History Museum Belgrade and the Croatian Natural History Museum. Fossil material was collected from the Badenian (Middle Mio­ cene) deposits of the south and southwestern margin of the Cen­ tral Paratethys. The age of the analyzed specimens from Serbia and Bosnia and Herzegovina stored at the Natural History Museum Belgrade is the Lower Badenian, while other Middle Miocene findings are questionable in age and require further research. During the upper part of the Lower Badenian, the species had a wide geographic distribution, which implys an open marine connection of the Central Paratethys with other marine areas. According to the available fossil record, Fissidentalium badense lived on a muddy to muddy­sandy substrate.
