Ein primitiver Acanthodier (Pisces) aus dem Unterdevon Lettlands

Latviacanthus ventspilsensis n.gen., n.sp. is described from a drilling core at Ventspils, Latvia, U.S.S.R. It is placed near Euthacanthus, Climatiidae, chiefly on the basis of similarities in the gill region (1 hyoid and 3 accessoric gill covers). Main features of Latviacanthus are: palatoquadrate and Meckel’s cartilage ossified as a single element each, multiple-cuspid teeth not fused to the jaws, slender pectoral spine, weakly developed dermal shoulder-girdle.
