General description

Specimens of this species possess a large white peripheral flange composed of a mass of calcareous spicules similar to that illustrated in the original description of Carterina spiculotesta (Carter, 1877). Tests are trochospiral throughout with chambers increasing rapidly in size. The last whorl comprises only 2-3 chambers. The deep umbilicus may be filled up with a spicular mass that may extend into the peripheral flange. Only the first (about 10) chambers are brownish in color, the other ones are yellowish or white. The spicules are elongated, fusiform, arranged somewhat parallel to the periphery on the spiral side and radial on the umbilical side.

General description

V. fragilis has a calcareous test with a high triserial chamber configuration. Numerous elongated or oval-shaped small pores are visible on the test surface . A narrow, elongated tear-shaped aperture is situated at the inner margin of the ultimate chamber and extends toward the apex. A tooth plate stretches through the chambers and terminates around the aperture. Serrate undulation is developed on the basal end of each chamber. Arched sutural openings with interposed bridges of basal chamber wall are developed in each chamber.

Zaninettia conica

Original description Brönnimann P., Whittaker J.E., 1983, Revue de Paléobiologie, 2, 13-33
Further reference Pawlowski J., Holzmann M., Debenay J.-P., accepted for publication, Journal of Foraminiferal Research

General description

In this species, the first stage is a small, high, conical trochospire consisting of about 2 whorls, flattening out toward the periphery, with a subcircular outline. It is shallow-concave on the umbilical side, with a deep axial depression. The following chambers that make up the flattened second ontogenetic stage are crescent with secondary septa. They become increasingly elongated and are added irregularly, resulting in an unevenly lobed outline of the test. There is no peripheral flange. The spirally elongate-crescent chambers appear as symmetric, petal-shaped, on the umbilical side. The walls are made up of typically “rounded-rectangular” truncated spicules that are scattered. The first chambers are dark brown to blackish while the remaining ones are yellowish or white.

Further reference Pawlowski J., Holzmann M., Debenay J.-P., accepted for publication, Journal of Foraminiferal Research

General description

The wall is made up of typically “rounded-rectangular” truncated spicules arranged irregularly. The test begins with a very low-convex trochospiral stage of about 10 chambers, arranged in 2 coils, with oblique sutures. In this stage chambers increase slowly in size. Chambers of the second stage become rapidly elongate-crescent. They are added irregularly and the last ones may have lengths of about one third of the circumference of the chambered test. They are subdivided by secondary septa. The last stage is represented by an irregularly contoured flange, containing randomly dispersed spicules embedded within fine agglutinated particles. The first stage and part of the second stage of the test are dark brown in color. The end of the second stage and the flange are yellowish or white.
