Article: The classification and stratigraphical distribution of the Globigerinaceae, Part 1

In this paper, the first of a series on the superfamily Globigerinaceae (Carpenter, emended), a new classification is given, comprising three families and eleven subfamilies. Two new subfamilies (Globorotaloidinae and Sphaeroidinellinae), two new genera (Pseudohastigerina and Sphaeroidinellopsis), two new subgenera (Praeglobotruncana (Clavihedbergella) and Hastigerina (Bolliella)), and one new species (Hastigerina (Bolliella) adamsi) are proposed. Particular attention is given to problems resulting from iterative evolution, and the broad aspects of the phylogeny of the superfamily are discussed.
