Abstract

Nedaleko spilje Veternice na jugozapadnim padinama Medvednice nalazi se proučavano područje za koje se uspostavilo da je fosilno vrlo bogato i zanimljivo. Zabilježena je velika prisutnost koponožaca, osobito roda Cadulus, koji je na području Centralnog Paratetisa u dostupnoj literaturi zabilježen samo jednom. Postavlja se pitanje kojim putem su kadulusi migrirali da bi došli na područje današnje Medvednice. Uz najzastupljenije koponošce, nađene su i foraminifere, ostrakodi, koralji, školjkaši,... More mahovnjaci, serpulidi, ježinci i ribe. Analizirano je devet uzorakalapora metodom mokrog prosijavanja, kalcimetrije te mikroskopskom paleonotološkom analizom. Na temelju analizirane faune i rezultata kalcimetrije dana je pretpostavka o paleookolišu istraživanog područja. Radi se o plitkomorskom taloženju sa čestim utjecajem kopna (povećani terigeni donos te unos slatke vode). Starost naslaga je određena kao srednjobadenska. Less

Abstract (english)

The study area is situated on the southwestern slopes of Mount Medvednica, nearby the Veternica cave. This area is rich in interesting fossils. Many scaphopods were found, along with the genus Cadulus, which has only been identified once before in the area previously occupied by the Central Paratethys. A question is then posed: how did the Cadulus migrate to Medvednica and more specifically, through which path? Alongside the aforementioned scaphopods, other fossils were found – including... More foraminifera, ostracods, corals, molluscs, bryozoa, serpulids, urchins and fish. Nine samples of marl were analyzed using wet sieving, calcimetry and palaeontological microscopy methods. Based on the fauna analysis and calcimetry results, a paleoenvironmental reconstruction of the study area is proposed. It is suggested that the study deposits were subject to shallow water sedimentation with terrigenous sediment and fresh water influx. The samples were determined to be of middle Badenian age. Less
