Abstract

Considered are Upper Cretaceous gastropods of family Acteonellidae from the siliciclastic-carbonate sedimentary succession of Gosau type at Grajski grič near Slovenj Gradec. Two forms, Trochactaeon giganteus (Sowerby, 1835) and T. cf. goldfussi (d`Orbigny, 1850) were determined. Foraminifera Fleuryana adriatica De Castro, Drobne & Gušić, 1994 determine the Upper Maastrichtian age of the limestones with trochactaeons.

Key words: gastropods, Trochactaeon (Acteonellidae), Foraminifera, Gosau facies, Upper Cretaceous, Upper Maastrichtian, Grajski grič, Slovenj Gradec, Slovenia

 

V prispevku so obravnavani zgornjekredni polži iz družine Acteonellidae iz siliciklastično-karbonatnega zaporedja gosavskega faciesa, ki so najdeni pri Grajskem griču blizu Slovenjega Gradca. Omenjena lokaliteta predstavlja novo najdišče krednih polžev gosavskega faciesa. Ugotovljeni sta dve obliki polžev Trochactaeon giganteus (Sowerby, 1835) in T. cf. goldfussi (d`Orbigny, 1850). Foraminifera Fleuryana adriatica De Castro, Drobne & Gušić, 1994 in ostala mikrofosilna združba določajo apnencem s trohakteoni zgornjemaastrichtijsko starost.

Ključne besede: polži, Trochactaeon (Acteonellidae), foraminifere, gosavski facies, zgornja kreda, zgornji maastrichtij, Grajski grič, Slovenj Gradec, Slovenija
