NEW MIDDLE TRIASSIC BELL-SHAPED NASSELLARIAN RADIOLARIA FROM ALPINE AND CARPATHIAN AREAS

Abstract

This paper is a continuation of a previous one in which I described and revised different Middle Triassic nassellarian Radiolaria from the Alps and Carpathians illustrated with drawings. On the present paper, are described two new groups of Middle Triassic dicyrtid Nassellaria with bell-shaped shell from the same area to enrich the inventory of these microfossils. Two new families (Gorispelidae and Humerocyrtiidae), five new genera (Silicotintinnabulum, Colpotrelus, Gorispela, Pozsvartia and Humerocyrtis) and 30 new species are described from these genera and illustrated with drawings.
