Original Description
Extra details from original publication
Discussion: This species developed during the early Pliocene and gave rise to G. miocenica in the late Pliocene. There is suspicion that it is also an evolutionary antecedent of G. multicamerata. Globorotalia praemiocenica differs from G. multicamerata in having higher arched chambers and a thin caria and from G. miocenica in having a distinct lobulate peripheral chamber margin and typically a strongly convex spiral side. The type locality for G. limbata is redeposited fossil sediment of probable middle Miocene age from near Rimini, Italy, which is also the type locality for G. menardii. Observable differences between these two species are negligible. Similarly, G.pseudomiocenica Bolli & Bermudez (1965), described from the early late Miocene of coastal Venezuela, is more closely akin to G. menardii than to G. praemiocenica, n. sp.
