Abstract

Na otočiću Trstenik, južno od otoka Korčule, otkrivene su naslage s ostacima ježinaca. Vršena su mjerenja na tri profila te su prikupljeni uzorci za mikroanalizu. Temeljem odredbe mikrofacijesa vapnenaca i tafonomije ježinaca utvrđen je taložni okoliš koji odgovara plitkomorskom okolišu otvorene unutarnje platforme. Opisani ježinci pripadaju skupini nepravilnih ježinaca, redu Cassiduloida koji su živjeli semi-infaunalno. Stratigrafski raspon proučavanih naslaga određen je temeljem biostratigrafskih raspona rodova bentičkih foraminifera Solenomeris sp., Rhapydionina sp., Cuvillierinella sp. i Spirolina sp. te odgovara rasponu mastriht – eocen.

Abstract (english)

Echinoid-bearing layer was discovered on Trstenik islet, south from the island of Korčula. Field studies were conducted at three outcrops and samples were collected for microanalysis. Based on the microfacies analysis of the limestones and the taphonomy of echinoids, the palaeoenvironment corresponded to the facies zone of a shallow marine setting of the open inner platform. Described echinoids belong to the group of irregular echinoids, the order Cassiduloida, which live semi-infaunal. Benthic foraminifera genera were used to determine the age of the studied deposits which corresponds to Maastrichtian – Eocene range.
