Globorotaliacea
Sign in to saveAlso known as Globorotalioidea
The Globoroatioidea (Globorotaliacea in older classifications) constitutes a superfamily of Cenozoic plantonic foraminifera. It is part of the suborder Globigerinina. Globoroatioidea have trochospiral tests with rounded to carinate peripheries, the walls of which are of finely lamellar, perforate, of optically radial calcite, with an inner organic lining. The surface of these tests is smooth, lacking spines, but may be covered with pustules or pitted, and may have one or more large pores at the center. There is a single primary aperture that may be bordered by an imperforate lip, as well as po

The Globoroatioidea (Globorotaliacea in older classifications) constitutes a superfamily of Cenozoic plantonic foraminifera. It is part of the suborder Globigerinina. Globoroatioidea have trochospiral tests with rounded to carinate peripheries, the walls of which are of finely lamellar, perforate, of optically radial calcite, with an inner organic lining. The surface of these tests is smooth, lacking spines, but may be covered with pustules or pitted, and may have one or more large pores at the center. There is a single primary aperture that may be bordered by an imperforate lip, as well as possible supplementary apertures.
Families included in the Globoroatioidea, in temporal sequence, as per Loeblich and Tappan, 1988, are the: Eoglobigerinidae L. Paleocene (L. Danian) Truncorotaloididae M. Paleocene to U.Eocene Catapsydracidae Paleocene to Holocene Globorotaliidae Paleocene to Holocene Candeinidae M. Eocene to Holocene Pulleniatinidae M. Miocene to Holocene
