The classification of the Jurassic to Albian Globigerinina is revised, phyletically and taxonomically. The Favusellacea comprise the genera Globuligerina (Jurassic) and Conoglobigerina (Jurassic-earliest Cretaceous), its descendant Favusella (Hauterivian to Cenomanian) and Ascoliella nov. (type species A. scotiensis nov.) (Aptian-Albian). The Globigerinacea include the families Praehedbergellidae nov. (from which the Hedbergellidae and its allies are descended) and the Schackoinidae; both are microperforate and nonmuricate. The Praehedbergellidae originate with Gorbachikella nov. (type species G. kugleri (Bolli)) and include Praehedbergella (Hauterivian-Aptian, including P. tatianae nov., P. grigelisae nov.), Wondersella, Blefuscuiana nov. (including B. kuznetsovae nov., B. mitra nov., B. multicamerata nov., B. speetonensis nov., B. globigerinelloides (Subbotina) lobulata nov. and B. occulta (Longoria) quinquecamerata nov.) (Barremian to Danian) and Lilliputianella nov. (including L. longorii nov.) (Aptian). The Schackoinidae includes Blowiella, Leupoldina and Schackoina. All the genera have their diagnoses emended as they are reinterpreted in accordance with the revised phyletic classification. Suggestions are made to explain the adaptive evolution of the taxa to the developing Early Cretaceous ocean.
