A carbonate cobble was collected in a creek near Slovenj Gradec (Slovenia). It comprises Trochactaeon gastropods as well as foraminifera Fleuryana adriatica and Cuneolina ketini from a subtidal environment with agglutinated and porcelaneous benthic foraminifera. Packstone-grainstone of the structural type contains the abovementioned foraminiferal taxa, which are previously undetermined in this part of the Upper Cretaceous Tethyan realm. Stratigraphic data from this area, together with the determined microfossil assemblage of the carbonate cobble, indicate the upper part of Lower Campanian age, implying an extension of the F. adriatica and C. ketini stratigraphic range. The paleoniche within the Tethyan realm in which F. adriatica thrive is the shallowest part of the subtidal, close to peritidal conditions. It was developed on a relatively harder substrate that resulted from a laterally more pronounced paleorelief which enabled the shifting of hyaline benthic foraminifers towards the shallowest part of the subtidal. Their paleoniche is laterally absent from protected paleoenvironments with soft muddy substrate and a relatively high carbonate sedimentation rate, colonized with elevator rudists, as well as from relatively higher water energy paleoenvironments with completely hard grainstonerudstone substrate.
UvodV Istri poteka v smeri od severozahoda proti jugovzhodu dobrih 20 km {irok pas paleogenskih skladov, ki sestojijo pretežno iz fli{nih kamnin, laporastih apnencev in apnencev. Znotraj obsežnih in debelih profilov fli{a so eocenski -lutetijski apnen~evi bazalni debelozrnati klastiti, bre~e in konglomerati, v katerih je veliko ostankov numulitin in drugih zelo razli~nih fosilnih organizmov. Ve~ji izdanki teh bre~ in konglomeratov so v profilih v bližnji in {ir{i okolici Gra~i{}a (slika 1). Raziskovani profili so tudi ob cesti nekako na sredini poti med Pazinom in Pi}nom v Istri. To obmo~je obiskujemo in pregledujemo že {tiri desetletja. V tem ~asu smo zbrali tudi zadovoljivo {tevilo hi{ic polihetov za primerno raziskavo in dolo~itev njihove taksonomske pripadnosti. Na{li smo le planispiralno zavite hi{ice, ki pripadajo polihetu ene vrste Rotularia spirulaea, ki je najdena v {tevilnih deželah Mediterana ter severno in vzhodno od tod, torej na obmo~ju nekdanjega Tetidinega sedimentacijskega prostora. Serpulidni ~rv Rotularia spirulaea iz eocenskih plasti pri Gra~i{}u v Istri, Hrva{kaThe serpulid worm Rotularia spirulaea from Eocene beds near Gra~i{}e in Istria, Croatia Izvle~ekV prispevku so predstavljeni nekateri izbrani primerki sedentarnih polihetov vrste Rotularia spirulaea (Lamarck, 1818), ki so najdeni v srednjeeocenskih -lutetijskih apnen~evih bre~ah in konglomeratih oziroma olistostromi, v profilu pod zaselkom Gra~i{}e blizu Pazina v Istri na Hrva{kem. Primerki so redki, razli~nih oblik in velikosti ter nastopajo skupaj s {tevilnimi numulitinami, koralami, mehkužci, iglokožci, mahovnjaki, litotamnijami in drugimi fosilnimi ostanki. Omenjene kamnine in njihova vsebina so sestavni deli istrskih paleogenskih bazenov oziroma Pazinskega fli{nega bazena. AbstractIn paper several selected specimens of sedentary Polychaetes of species Rotularia spirulaea (Lamarck, 1818) are presented. They were found in Middel Eocene -Lutetian calcareous breccias and conglomerates, respectively olistostromes, below the village of Gra~i{}e near Pazin in Istria (Croatia). The rare individuals are of various shapes and sizes, and they occur among numerous nummulitines, corals, molluscs, echinoderms, bryozoans, lithothamnias and other fossil remains. The mentioned rocks and their contents are constituting parts of the Istrian Paleogene basins, in this istance of the Pazin flysch basin.

UvodV kamnolomu Lipovica je najdenih veliko razli~nih miocenskih fosilnih ostankov, prevladujejo rde~e alge, luknji~arke, mehku`ci, mahovnjaki in igloko`ci, veliko manj je ramenono`cev, zelo redki pa so ostanki ~lenono`cev in vreten~arjev.Na najdbe miocenskih rakovic v Tunji-{kem gri~evju je prvi opozoril {entur{ki `u-»Kranjska rakovica« iz srednjemiocenskih -badenijskih skladov kamnoloma Lipovica nad Bri{ami The »Carniolan crab« from Middle Miocene -Badenian beds in the Lipovica quarry above Bri{e, Slovenia Vasja MIKU@ & Jernej PAV[IK atedra za geologijo in paleontologijo, Kratka vsebina Obravnavani so ostanki »kranjske rakovice« dekapodne vrste Tasadia carniolica (Bittner, 1884) iz srednjemiocenskih -badenijskih skladov kamnoloma Lipovica nad Bri{ami. Vrsta je bila prvikrat ugotovljena v Sloveniji v najdi{~u med Tunjicami in Kamnikom. Posamezni skromni ostanki so registrirani tudi v drugih slovenskih najdi{~ih.

AbstractExamined were remains of »Carniolan crab« of the decapod species Tasadia carniolica (Bittner, 1884) from Middle Miocene -Badenian beds in the Lipovica quarry above bri{e. The species was first established in Slovenia in a locality between Tunjice and Kamnik. Individual modest remains were registered also in other Slovenian localities. Later the species was found also elsewhere in the Central Paratethys and in the region of the Boreal bioprovince.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
