Middle Miocene Calcareous Nannoplankton of NE Slovenia (Western Central Paratethys)

The monograph presents Badenian calcareous nannoplankton from NE Slovenia. Several hundred samples from 22 measured sections have been studied. In total, 109 species of calcareous nannoplankton are determined and described, many of which are new to Slovenia. The entire interval studied was assigned to the Middle Miocene. The excellent preservation and high species diversity enabled a precise subdivision of this interval into 6 successive interval zones, correlated with the absolute time scale (15.5 – 13.1 Ma) and with the 3rd order eustatic cycles (TB2.3, TB2.4 and TB2.5). Lists of all examined nannoplankton assemblages and their paleoecological analyses are also included. The monograph is a comprehensive review of the taxonomy, biostratigraphy and paleoecology of Miocene calcareous nannoplankton in the western part of the Central Paratethys.Monografija predstavlja rezultate celovite študije kalcitnega nanoplanktona iz badenijskih plasti Slovenskih goric. Iz več sto vzorcev z 22 posnetih profilov je določenih in opisanih 109 vrst nanofosilov, mnoge med njimi so nove za Slovenijo. Preučevani interval je v celoti uvrščen v srednji miocen. Odlična ohranjenost nanofosilov in velika diverziteta sta omogočili zelo natančno razdelitev obravnavanega intervala na 6 lokalnih intervalnih con, ki so korelirane z absolutno časovno lestvico (15,5–13,1 milijonov let) ter z globalnimi evstatičnimi cikli 3. reda (TB2.3, TB2.4 in TB2.5). Monografija vsebuje tudi podatke o sestavi vseh obravnavanih nanoplanktonskih združb in podaja paleoekološko analizo. Monografija je izčrpen prikaz taksonomije, biostratigrafije in paleoekologije miocenskega kalcitnega nanoplanktona v zahodnem delu Centralne Paratetide

Badenian discoasters from the section in Lenart (Northeast Slovenia, Central Paratethys)

In Slovenske gorice, south of Lenart, a 20 m profile of Middle Miocene strata has been exposed. During previous research numerous discoasters have been found among other coccoliths. In Slovenia Miocene discoasters have only been found in Badenian sedimentsin Slovenske gorice and they are particularly useful for paleoecological reconstructions.Additional samples were taken from three selected sections in the middle part of the profile, targeting strata with the greatest abundance of discoasters. In two of the three examined sections 9 species of discoasters were identified, the most abundant being D.exilis and D. variabilis. Even though warm water species were found in samples from all three sections, discoasters only occured in two short intervals. This pattern is not a result of temperature changes and is in our opinion connected with the changes in nutrient levelsof seawater

A new cephalopod find in the Eocene beds near Grdoselo in Istria, Croatia

The article presents a cast fossil of a cephalopod found in sandy limestones (packstones) of Eocene age nearGrdoselo in Central Istria. The phragmocone remains most probably belong to the nautilid species Eutrephoceras(Simplicioceras) centrale (Sowerby, 1812). We have determined the age of the fossil with calcareous nannoplankton.The nannofossil assemblage is typical of the Middle Eocene and allows the assignment to the biozone NP15(Nannotethrina fulgens) of the Middle Eocene

The brachiopod Lingula from the Middle Miocene – Badenian beds of Slovenia

The article discusses the first find of an inarticulate brachiopod in Slovenia. The fossil was discovered in Miocenebeds in Badenian sandy and marly limestones outcropping in the Plesko quarry near Trbovlje. It belongs to thespecies Lingula dregeri Andreae, 1893

Fish vertebra from Miocene beds at Govce, Slovenia

The article discusses a vertebra and a small shark tooth found in the Miocene Govce sandstone near Govce west of Laško in central Slovenia. The vertebra belongs to a shark of the superorder Galeomorphii but we could not determine it with greater precision. The small tooth was assigned to Carcharias cf. taurus Rafinesque, 1810. The nannofossils in the sample are scarce and did not allow dating at biozone precision

Porgy fish teeth in Miocene marl from Mastni hrib near Škocjan, Slovenia

The article discusses fossil porgy fish teeth found in Middle Miocene (Badenian) sandy marl from Mastni hrib near Škocjan in Dolenjska. The teeth belong to the species Pagrus cinctus (Agassiz, 1836) and represent the first find in the Krka basin. In sediments of the Central Paratethys and the Mediterranean, the fossil remains of porgy fish are relatively common

Annelids in the Miocene lithothamnion limestone from Zgornja Pohanca, Slovenia

Presented and discussed are remains of Middle Miocene – Badenian annelids in limestone fragments that consistmostly of tubular-rodlike annelids and lithothamnions. Segmented limestone tubules are largely fragmented andfilled with calcite. By their morphology and size they are comparable to polychaetes of the Serpulidae family. Tubularremains could be attributed to genera Protula, Hydroides or Vermiliopsis? The samples of annelidic limestonewith polychaetes were found in environs of Zgornja Pohanca near Kr{ko in eastern part of central Slovenia

Outcrop-scale evidence for the Norian-Rhaetian extensional tectonics in the Slovenian Basin (Southern Alps)

No direct evidence for the Norian-Rhaetian tectonic activity has been gathered from the Slovenian territoryuntil now. In the quarry in the vicinity of Škofja Loka, several palaeofaults transect the outcropping Bača Dolomite.The Norian-Rhaetian age of the Bača Dolomite is confirmed with the finding of the conodont species Norigondolellasteinbergensis (Mosher, 1968). The formation of the faults is related to the openning of the future JurassicPiemont-Ligurian Ocean to the west of the studied area, or with the diminishing influence of the Neotethys (Meliana) Ocean to the east

Miocene pteropods from Polički Vrh in Slovenske gorice, northeast Slovenia

In the paper relatively modestly preserved but very numerous pteropod remains from Middle Miocene – Badenianmicaceous marlstones of Poli~ki Vrh locality in Slovenske gorice, northeastern part of Slovenia are described.The fossils were attributed to the pteropod family Cliidae Jeffreys, 1869, respectively the species Clio pedemontana(Mayer, 1868). They represent the first documented finds of this species in Slovenia, and so far also the southernmostoccurrence of the pteropods belonging to this species in Neogene beds of the Styrian basin in the Central Paratethys
