Taxonomy of Bulgarian Triassic foraminifera. II. Families Endothyriidae to Ophthalmidiidae

Seventy-five species belonging to 32 genera are described. They are distributed in the families: Endothyriidae (Endothyra, Haplophragmella, Endothyranella), Tetraxidae (Tetrataxis), Involutinidae (Lamelliconus, Triadodiscus, Angulodiscus, Arenovidalina, Aulotortus, Semiinvoluta, Trocholina), Spirillinidae (Spirillina, Conicospirillina, Turrispirillina), Cornuspiridae (Cornuspira, Rectocornuspira, Meandrospira, Meandrospiranella, Calcitornella, Planiinvoluta, Turriglomina), Hemigordiopsidae (Agathammina, Hemigordiopsis, Hemigordius, Nodogordiospira), Nubeculariidae (Gheorghianina, Venelloidea), Ophthalmidiidae (Cornuloculina, Еophthalmidium, Gsolbergella, Ophthalmidium, Paraophthalmidium). In the article the Loeblich, Tappan's (1988) classification is applied. The foraminifers here presented derived from 55 bore-holes and 33 outcrops from different regions of Bulgaria.
