Wondersella athersuchi, gen. et sp. nov., is a uniquely streptospiral hedbergellid apparently confined to the latest Aptian in pelagic micritic limestones of the Middle East. This taxon probably ...characterised highly stratified, oceanic-marginal environments of central, palaeoequatorial Tethys.
"The availability of the name Hastigerina digitata Rhumbler, 1911, has recently been disputed, an attempt having been made to substitute Hastigerinella eocanica Nuttall, 1928, as type species of the ...genus Hastigerinella Cushman, 1927. This is refuted, and a neotype for Hastigerina digitata Rhumbler, 1911 = Hastigerinella digitata (Rhumbler) Cushman, is designated in accordance with the International Code of Zoological Nomenclature."
Studies of many geographically widely separated stratigraphical sections covering the late Miocene to Recent interval have allowed the origin and evolution of species referable to the genus ...#ITPulleniatina #MEto be traced. The evolutionary sequence #ITPulleniatina primalis, #MEn. sp., #ITP. obliquiloculata praecursor, #MEn. subsp., #ITP. obliquiloculata obliquiloculata #MEand #ITP. obliquiloculata finalis, #MEn. subsp., is shown to be useful in biostratigraphy. #ITPulleniatina spectabilis #MEis recognised as forming a separate evolutionary line from #ITP. primalis #MEand as having a short range in the Pliocene of the Indo-Pacific province. #ITPulleniatina #MEseems to originate from #ITGloborotalia (Turborotalia) acostaensis #MEBlow, 1959, and the holotype of this form is re-illustrated. #ITGlobigerina inflata #MEd'Orbigny, 1839, is shown to be unrelated to #ITPulleniatina obliquiloculata #ME(s. l.), and a neotype for the former taxon is now proposed. The meaning of streptospiral coiling is examined. The new monotypic genus #ITRotaliatinopsis #MEis proposed to accommodate #IT'?Pulleniatina semi-involuta' #MEGermeraad, 1946, which is unrelated to the Globigerinacea.
The primary types of the foraminiferal species Globorotalia barisanensis LeRoy, 1939, Globorotalia fohsi Cushman and Ellisor, 1939, and Globorotalia lobata Bermúdez, 1949, are refigured and ...redescribed; their morphology and taxonomy are discussed and reapplied to biostratigraphy. The new species Globorotalia (Turborotalia) peripheroronda, G. (T.) peripheroacuta and Globorotalia (G.) praefohsi are proposed and discussed in order to define taxonomically forms which have previously been incorrectly assigned to G. barisanensis and/or G. fohsi. All the taxa discussed have been biostratigraphically related, and their phylogeny is briefly outlined. The evidence from the Kassikan section of Sumatra (LeRoy, 1952) has been reviewed, compared and contrasted with the biostratigraphy proposed by Bolli (1950, 1957) and Blow (1959) for the relevant parts of the Neogene successions of planktonic foraminifera.
A new and distinctive genus of hauraniid foraminifera has been found in Liassic rocks of the island of Socotra (Yemen) and of the United Arab Emirates; both are believed to be of Toarcian age.
Un ...genre nouveau et caractéristique de foraminifère hauranid a été trouvé dans les roches liassiques de Socotra (Yémen) et des Émirats Arabes Unis; les deux sont présumées être d'âge Toarcien.
Revision of a previously published classification of the Globigerinaceae; includes designation and descriptions of lectotypes for Globigerina siphonifera and G. aequilateralis and a neotype for ...Nonionina pelagica.
