Taxonomy of Bulgarian Triassic foraminifera. I. Familes Psammosphaeridae to Nodosinellidae

74 species belonging to 31 genera are described. They are distributed in the families: Psammosphaeridae (Psammosphaera, Sorosphaera), Hyppocrepinidae (Hyppocrepina, Hyperamminoides), Ammodiscidae (Ammodiscus, Ammovertella, Tolypammina, Gandinella, Glomospira, Glomospirella, Pilammina, Pilamminella, Rectoglomospira). Hormosinidae (Reophax), Lituotubidae (Lituotuba, Plagioraphe), Lituolidae (Ammobaculites), Placopsilinidae (Placopsilina), Orbitopsellidae (Labyrinthina), Spiroplectamminidae (Spiroplectammina), Pseudobolivinidae (Pseudobolivina), Trochamminidae (Trochammina), Verneuilinidae (Verneuilinoides, Gaudryina, Gaudryinella), Cuneolinidae (Palaeolituonella), Textulariidae (Bigenerina), Earlandinidae (Earlandia), Caligellidae (Caligella), Earlandinitidae (Earlandinita) and Nodosinellidae (Nodosinella). In the article the LoebIich, Tappan's (1987) classification is applied. The foraminifers presented here derived from 54 borehole sections and 31 outcrops from different regions of Bulgaria.
