First record of Discinidae brachiopods from the Miocene of Hungary

Although Discinidae brachiopods are rare components of Neogene benthic assemblages, several records were published from the Miocene of the Central Paratethys (Poland, Ukraine, Czech Republic, Austria, and Bulgaria). However, until now discinid brachiopods have never been mentioned from Hungary. Recently, remains of one species, Discradisca cf.polonica(Radwańska et Radwański, 1984) were found at two Middle Miocene (Badenian) localities of the Bakony Mts. Two fragments were discovered in old washed samples (Pusztamiske Formation) from the Szabó sand pit of Várpalota in the collection of the Hungarian Natural History Museum, Budapest. The same species is much more numerous in a new material collected at Nyirád locality. Here hundreds of very eroded and fragmentary discinids were found in the Pusztamiske Formation, while the overlying Leitha Limestone Formation contains less, but sometimes more or less complete specimens. D. polonicaseems to be restricted to shallow water environments. The Hungarian record is one of the most southern known occurrences of discinid brachiopods in the Central Paratethys (together with the very limited Bulgarian material). With 22 figures

Sporadic Pliocene and Pleistocene brachiopods in Naturalis Biodiversity Center (Leiden, the Netherlands) : records from the Mediterranean, and the North Sea Basin

Th e Cenozoic Mollusc Collection of the Naturalis Biodiversity Center (NBC) contains several Pliocene and some Pleistocene brachiopods from the Mediterranean (5 Italian localities), and from the North Sea Basin (2 English localities, 1 French locality, 4 Dutch localities). Th e stud- ied samples altogether yielded more than 1000, mostly fragmentary specimens (8 genera, 8 spe- cies). Th e Italian Pliocene (and Pleistocene) assemblage is dominated by large terebratulids ( Te r e b - ratula ampulla ), while rhynchonellids ( Aphelesia bipartita ) and cancellothyridids ( Terebratulina retusa ) are rare. Th e Coralline Crag samples of England are characterized by large terebratulids ( Pliothyrina sowerbyana ) and lingulids ( Glottidia dumortieri ), the zeilleriid Macandrevia cranium is rare. Th e only French locality yielded few brachiopods, with relatively higher diversity ( P. s o w e r - byana is more common, the others are rare: G. dumortieri , M. cranium , Argyrotheca cf. plicata ). Th e Dutch Pliocene samples are dominated by mostly fragmentary lingulids ( G. dumortieri ), while the others are much less common ( Notosaria nysti , P. sowerbyana , T. retusa , M. cranium ). Th is is the fi rst photo documentation of N. nysti . With 64 fi gures

A brachiopodák faunafejlődése Magyarországon a kréta végétől a miocénig (rendszertan, paleoökológia, paleobiogreográfia) = Faunal changes of brachiopods in Hungary from the Late Cretaceous to the Miocene (systematics, paleoecology, paleobiogeography)

Paleogén és neogén brachiopodákat vizsgáltam különböző hazai és külföldi lelőhelyekről. Monospecifikus paleocén együttest írtunk le Ausztriából (új nemzetség, új faj). Hét hazai eocén felszíni feltárás és 7 mélyfúrás alapján 6 nemzetség 7 faját írtuk le (1 új faj, másik négy faj első említése Magyarországról). Feldolgoztuk a bakonyi eocén nummuliteszes mészkő brachiopoda faunáját (3 faj, 1 új nemzetség leírása). Nagyon gazdag (12 nemzetség, 12 faj) oligocén faunát dokumentáltam a novaji Nyárjas-tetőről. A Középső Paratethys oligocénjének brachiopoda faunája eddig csaknem ismeretlen volt. Számos faj rétegtani elterjedését terjeszti ki a novaji anyag az oligocénig. Tisztáztam a noszvaji Nagyimány oligocén brachiopoda faunájának rendszertani helyzetét. Revideáltuk a Meznerics-féle miocén brachiopoda gyűjteményt. Első ízben írtam le bekérgező epifauna elemeket a Középső Paratethys mikromorf brachiopodáin (Bánd). Több badeni brachiopoda faj földrajzi elterjedését pontosítottam a leideni Naturalis Múzeum anyaga alapján. Mikromorf brachiopodák belső morfológiájának megismerésére kezdeményeztem mikro CT vizsgálatokat (részleges sikerrel). Az eddig ismert leggazdagabb hazai kainozoós chiton faunát írtam le a Bakonyból (8 faj, 4 először Magyarországról). Első alkalommal ismertettünk chitonokat az ukrajnai és a bulgáriai miocénből. A magyarországi badeni Bryozoák alapján öt különböző fáciest és 3 őskörnyezeti típust különítettünk el a hazai badeniben. | Paleogene and Neogene brachiopods were studied from Hungarian and foreign localities. Monospecific Paleocene assemblage was described from Austria (new genus and species). 7 species of 6 genera were described from 7 Hungarian Eocene surface localities and 7 boreholes (1 new species, 4 species first time from Hungary). Brachiopods of Middle Eocene nummulitic limestone of the Bakony Mts were published (3 species, 1 new genus). Diverse (12 species, 12 genera) Oligocene fauna was documented from Novaj. Until now, the Oligocene brachiopods of the Central Paratethys were poorly known. The stratigraphical distribution of several species was extended to the Oligocene. Pliothyrina was identified for the first time from Hungary (Noszvaj). Meznerics’s Miocene brachiopod collection was revised. Epifaunal encrusters were recorded for the first time on micromorphic brachiopods of the Central Paratethys (Bánd). On the basis of the material of Naturalis Museum (Leiden), the geographical distribution of some Badenian brachiopods was refined. Partly successful micro CT monitoring was performed to study the internal morphology of micromorphic brachiopods. The richest known chiton fauna was described from Hungarian Cenozoic (Badenian, Bakony Mts, 8 species, 4 species first time from Hungary). Chitons were mentioned for the first time in the Miocene of Ukraine and Bulgaria. On the basis of Badenian Bryozoans of Hungary, 5 different facies and 3 paleonvironments were differentiated

Preliminary notes on Early and Middle Jurassic corals of the Bakony Mountains (Hungary)

Hettangian, Pliensbachian and Bajocian corals were examined from 6 localities of the Bakony Mountains. All of the suborders existed in Early and Middle Jurassic are present in the 80 specimens. The determined 6 genera belong to 4 suborders. 88% of the fauna is derived from the Domerian formations, but the number of taxa are nearly equal in Carixian, Domerian and Bajocian. Four genera appeared earlier in the Bakony Mountains, than in other areas. Seventy-seven specimens belong to solitary corals, and only 3 specimens are colonial. Two-third of the fauna is hermatypic at the Pliensbachian localities, but at the same time 80% of the specimens are ahermatypic in Bajocian. Fissures of seamounts and the edge of a seamount are represented at these localities. This means, that the top of the seamounts were nőt sinking below the depth of 100 m during the Pliensbachian, but it may have been below 100 m in Bajocian. The elongated morphotypes of corals stabilized themselves by root-like fixation, or the specimens had to be sunk in the loose sediments. Because the loose sediments were rare at the top of seamounts, the corals are sometimes overtumed (scolecoid specimens)

NEW DATA ON THE LATE MIOCENE BRACHIOPOD FAUNA OF TETTI BORELLI (PIEDMONT, N ITALY)

After a small brachiopod fauna was published in 2010 from the Tortonian Sant’Agata Fossili Formation of Tetti Borelli (N Italy), two new and more numerous brachiopod collections turned up from this locality. The Roest Collection in the Naturalis Biodiversity Center (Leiden, the Netherlands), and the Pavia-Giuntelli Collection in the Department of Earth Sciences of Torino University (Torino, Italy) contain 199 and 131 specimens, respectively. Based on the study of these collections, the Tetti Borelli brachiopod fauna is now much better known and more diverse. Additionally to the previously described six species (Cryptopora lovisati, Eucalathis aff. tauriniensis, Megathiris detruncata, Joania aff. falunica, Megerlia truncata, Lacazella mediterranea), another four taxa have been found (Lingula sp., Terebratulina retusa, Joania cordata, Argyrotheca sp.), and a new Megathyrididae genus and species (Borellithyris gaetanii n. gen. n. sp.) has been discovered. Another new species (Eucalathis giulioi n. sp.) is introduced on the basis of a dorsal valve of the Roest Collection and a previously illustrated ventral valve from the Janssen Collection. This is the sixth known fossil Eucalathis species, most of which are described on the basis of a few specimens. The Tetti Borelli brachiopods are mostly resedimented with different degree of transport, but the minute rhynchonellide Cryptopora seems to be more or less autochthonous

UPPER OLIGOCENE BRACHIOPODS FROM NW GERMANY, WITH DESCRIPTION OF A NEW PLATIDIINAE GENUS, GERMANOPLATIDIA N. GEN.

Upper Oligocene brachiopods of NW Germany were studied in two collections: the Naturalis Biodiversity Center (Leiden, the Netherlands) and the F. von der Hocht private Collection (Kerpen, Germany). Overall, six brachiopod taxa have been identified. Generic attributions of “Rhynchonella” supraoligocaenica Görges, 1952 (Aphelesia) and “Terebratula” pusilla Philippi, 1843 (Germanoplatidia n. gen) have been solved. The Chattian occurrence of Aphelesia is the first confirmed record of the genus in the Paleogene. Chattian record of the well-known Neogene Discinisca fallens (Wood, 1872) confirms that faunal change within brachiopods happened before the Paleogene/Neogene boundary. Similarly to the Mediterranean Terebratula-Aphelesia association, Aphelesia occurs also together with a large terebratulide genus (Pliothyrina) in the upper Oligocene Pre-North Sea. Along with some previously recognized genera (Orthothyris, Bronnothyris, Rugia), a further brachiopod evolutionary lineage was found to survive from the Mesozoic to the Paleogene (Aemula-Germanoplatidia n. gen.). According to the morphological characters of the genus and sedimentological characters of the surrounding deposits, Germanoplatidia n. gen. species lived on sandy bottom environments, and attached to small hard objects in the fine sediment by a pedicle longer than that of Aemula. Half of the identified species are endemic in Pre-North Sea. Here we document the first record of Argyrotheca bitnerae Dulai in Dulai & Stachacz, 2011 from the Pre-North Sea; this recently described species shows a cosmopolitan distribution in the Cenozoic. &nbsp
