“…Sporadic finds of the Oligocene and Miocene decapods from the Slovenian Basin were reported by Bittner (1884), Mikuž (2003b, 2010), Mikuž & Pavšič (2003), and Križnar (2009). Decapod faunas from the Karpatian of the Mura Basin were described by Glaessner (1928).…”

Decapod associations have been significant components of marine habitats throughout the Cenozoic when the major diversification of the group occurred. In this respect, the circum-Mediterranean area is of particular interest due to its complex palaeogeographic history. During the Oligo-Miocene, it was divided in two major areas, Medi terranean and Paratethys. Decapod crustaceans from the Paratethys Sea have been reported in the literature since the 19 th century, but only recent research advances allow evaluation of the diversity and distribution patterns of the group. Altogether 176 species-level taxa have been identified from the Oligocene and Miocene of the Western and Central Paratethys. Using the three-dimensional NMDS analysis, the composition of decapod crustacean faunas of the Paratethys shows significant differences through time. The Ottnangian and Karpatian decapod associations were similar to each other both taxonomically and in the mode of preservation, and they differed taxonomically from the Badenian ones. The Early Badenian assemblages also differed taxonomically from the Late Badenian ones. The time factor, including speciation, immigration from other provinces and/or (local or global) extinction, can explain temporal differences among assemblages within the same environment. High decapod diversity during the Badenian was correlated with the presence of reefal settings. The Badenian was the time with the highest decapod diversity, which can, however, be a consequence of undersampling of other time slices. Whereas the Ottnangian and Karpatian decapod assemblages are preserved virtually exclusively in the siliciclastic "Schlier"-type facies that originated in non-reefal offshore environments, carbonate sedimentation and the presence of reefal environments during the Badenian in the Central Paratethys promoted thriving of more diverse reef-associated assemblages. In general, Paratethyan decapods exhibited homogeneous distribution during the Oligo-Miocene among the basins in the Paratethys. Based on the co-occurrence of certain decapod species, migration between the Paratethys and the North Sea during the Early Miocene probably occurred via the Rhine Graben. At larger spatial scales, our results suggest that the circum-Mediterranean marine decapod taxa migrated in an easterly direction during the Oligocene and/or Miocene, establishing present-day decapod communities in the Indo-West Pacific.

“…Največ tovrstnih fosilnih ostankov v Sloveniji najdemo v eocenskih plasteh Istre (Pavlovec & Pavšič, 1985;Mikuž, 2010a) in miocenskih plasteh okolice Kamnika in Zasavja (križnar, 2006;križnar & Preisinger, 2008;Mikuž, 2010b;Mikuž & Pavšič, 2003). Iz miocenskih plasti slovenskega dela Štajerskega bazena Paratetide imamo do sedaj podatke o redkih posameznih najdbah fosilnih rakovic (glaessner, 1928;Mikuž, 2003), o bogati združbi fosilnih rakov deseteronožcev iz spodnjemiocenskih plasti nahajališča Činžat na severnem pobočju Pohorja pa sta poročala gašParič in Hyžný.…”

IzvlečekV članku predstavljamo nove najdbe rakovice Styrioplax exiguus Glaessner, 1928, ki dopolnjujejo naše poznavanje paleogeografske in stratigrafske razširjenosti te zanimive paratetidne vrste. Opisani so primerki s treh najdišč v miocenskih plasteh Slovenskih goric v neposredni bližini Maribora. S preiskavami fosilne kalcitne nanoflore smo določili srednjemiocensko starost plasti, ki so se odložile v globjemorskem okolju Centralne Paratetide. AbstractIn this paper we report new specimens of an interesting Paratethyan decapod Styrioplax exiguus Glaessner, 1928, which extend the known palaeogeographic and stratigraphic distribution of the species. The described specimens originate from three different localities from Miocene beds in the Slovenske gorice, in the vicinity of Maribor. By analysing the fossil nannoplankton assemblages we were able to determine a Middle Miocene age of these deep water beds of the Central Paratethys.

“…Beds of the Laško Fm. also exhibit greater decapod diversity, with Tasadia carniolica as the dominant species (Mikuž & Pavšič, 2003), associated with frequent specimens of Jaxea kuemeli Bachmayer, 1954 (documented in detail further below) and rarer burrowing ghost shrimp Calliax michelottii (A. Milne Edwards, 1860) (Hyžný & Gašparič, 2014). In the upper part of the Laško Fm.…”

“…Recently, a renewed interest has brought a number of publications from this area describing various decapod assemblages (Mikuž, , 2010Mikuž & Pavšič, 2003;Hyžný & Gašparič, 2014;Gašparič & Halásová, 2015;Gašparič & Hyžný, 2015;Gašparič & Ossó, 2016;Gašparič & Križnar, 2017). In this respect, the decapod fauna of the Tunjice Hills is yet undescribed, despite the fact that over 300 specimens belonging to at least 10 species were collected in recent years by local collectors (Gašparič & Brajković, 2016).…”

In the present paper we report on several new specimens of Jaxea kuemeli Bachmayer, 1954 from the Middle Miocene laminated sandstones from Košiše in Tunjice Hills. New and well-preserved material from shallow water environment of Laško Formation allows the re-evaluation of Jaxea cheliped morphology. The report enhances our knowledge of the variability of tooth formula in the cheliped of Jaxea kuemeli and opens questions about interspecific variations connected to temporal or ecological factors. We also discuss the environmental preferences of the species which is so far known exclusively from the Paratethys Sea. IzvlečekV pričujočem članku poročamo o novih primerkih deseteronožca vrste Jaxea kuemeli Bachmayer, 1954 iz srednjemiocenskih plasti nahajališča Košiše v Tunjiškem gričevju. Novi in dobro ohranjeni primerki, iz plitvovodnih plasti Laške formacije, omogočajo primerjavo morfologije škarnikov vrste Jaxea kuemeli. Opis novih primerkov razširja naše poznavanje razlik v zobni formuli škarnikov predstavljene vrste in odpira vprašanja o možni variabilnosti znotraj le-te, ki so lahko posledica časovnih ali okoljskih dejavnikov. V članku med drugim opredeljujemo tudi okoljske preference vrste, ki je do sedaj poznana le iz območja Paratetide.
