MILIOLIDAE - Acta Palaeontologica Polonica

MILIOLIDAE FROM MIOCENE OF POLAND 13
did not differ from that presented in 1917. In the next editions (1928,
1933, 1940 and 1948) there are already three families: Miliolidae,
Ophthalmidiidae (including, among other groups, the subfamily Cornuspirininae)
and Fischerinidae. The Miliolidae were not divided into subfamilies,
instead they comprised all d'Orbigny's genera, Wiesner's two
genera (Miliolinella and Biloculinella), Schlumberger's two genera (Massilina
and Sigmoilina), single genera introduced by other authors, e.g.
Nummoloculina Steinmann, Tubinella Rhumbler, Miliola Lamarck, and
several new genera described by Cushman himself: Nubeculina, Ammomassilina
and Flintina.
Cushman initiated a period of keen interest in the genetic classification
of the Foraminifera, which found its reflection in new elaborations appearing
every several years. At first the authors grouped the known miliolid
genera in one family, Miliolidae, after the fashion of earlier writers
(Galloway, 1933), and in three families, after the fashion of Cushman
(Chapman & Parr, 1936). Glaessner (1945) introduced a higher taxonomic
unit, i.e. the super-family Miliolidea divided into four families, with two
of which, the Miliolidae and Ophthalmidiidae, we are concerned. Sigal
(1952) and Pokorny (1958) applied the same division, in which they made
only small changes within the subfamilies. The classification proposed by
Bogdanowich and Voloshinova (in Rauser-Chernousova & Fursenko, 1959)
was characterized by the introduction of a still higher rank, i.e. the order
Miliolida comprising the superfamily Miliolidea and the families Cornuspiridae,
Ophthalmidiidae, Miliolidae and Familiae incertae. In the more
recent classification of Loeblich & Tappan (1964) the taxonomic unit of
the highest rank is the suborder Miliolina, which contains the superfamily
Miliolacea and the families Squamulinidae, Fischerinidae, Nubeculariidae
and Miliolidae. The families except the first one, split into subfamilies,
e.g. the Miliolidae into the Quinqueloculininae, Miliolinellinae, Miliolinae,
Fabulariinae and Tubinellinae, which differ from each other in aperture
type and also, partly, in wall structure.
Critical remarks on the division of the family Miliolidae in Loeblich &
Tappan's classification are given in Part I (1972).
BIOSTRATIGRAPHY
The Miocene sediments from which the Miliolidae under study come
are referred to two stages: the Tortonian (Badenian 2») and Sarmatian.
2) The conception of replacement of the term "Tortonian" with "Badenian" in
\.he Vienna Basin was put forward in the revision of the stratotypes and terms used
so far in the geochronological and lithostratigraphical scale for the Central
Paratethys region, initiated by the Congress of the Committee on Mediterranean
Neogene Stratigraphy in Bologna in 1967 (Papp. et al., 1968). This conception was
upheld by the CMNS Congress in Lyon in 1971 (Carloni et al., 1971) and the term
was recommended for the Central Paratethys region.
