Fossilien aus Riffkomplexen der alpinen Trias:Cheilosporites Wähner, eine Foraminifere?

摘要: The genusCheilosporitesWahner, a problematicum variously referred to algae and sponges, is widespread in Rhaetian reefs of the Alpine region. Its arborescent colonies are composed uniserial but branching rows chambers, penetrated by an axial siphon. chambers enlarge distally, undergo marked changes shape. These characters be found neither among nor characteristic many Foraminifera. Despite its relatively large size (chamber diameter up 4 mm, height colony probably 5 cm)Cheilosporites here tentatively Fortminifera, as only known representative new familiy Cheilosporitidae.
