Abstract

Na području Goranca, u blizini Čučerja, pronađena su nova nalazišta pteropodnih naslaga s foraminiferama, ostrakodima, skafopodima, morskim ježincima i vapnenačkim nanoplanktonom. Mikrofosili su izdvojeni tehnikom mokrog prosijavanja, dok su pteropodi analizirani mjerenjem visine, širine i apikalnog kuta kućice. Pteropodna fauna obuhvaća obilne primjerke vrste Vaginella austriaca koja je detaljno proučavana ovim istraživanjem. Pteropodi roda Limacina su prvi puta zabilježeni na južnim padinama... More Medvednice. Rodovi Diacrolinia i Creseis su na Medvednici prvi puta zabilježeni. Također dubokomorska tekstularidna foraminifera Bathysiphon i Rhabdammina predstavljaju prve nalaze tih rodova na širem području. Prema nalazima fosila i usporedbom sa susjednim, prethodno istraživanim lokalitetima, taložni okoliš je opisan kao morski, dok je starost uzoraka određena kao srednjobadenska. Less

Abstract (english)

At the Goranec locality, in the vicinity of Čučerje, new pteropod assemblages, associated with foraminifera, ostracods, scaphopods, echinoderms and calciferous nannoplankton, were identified. Microfossils were extracted from sediment by wet sieving technique, while pteropod specimens were analized by measuring height, width and apical angle of the shell. The pteropod fauna encompasses abundant specimens of Vaginella austriaca which was studied in detail in this research. Pteropods of the... More genus Limacina were recorded on southern slopes of the Medvednica for the first time. Genera Diacrolinia and Creseis were recorded in Medvednica for the first time. Also deep-marine textulariid foraminifera Bathysiphon and Rhabdammina represent the first finding of these genera in the wider area. According to fossil findings and comparing with neighbouring, previously studied localities, depositional environment is described as deep marine, while the age of samples is defined as the Middle Badenian.
