The test wall is composed of imperforate
calcite, a character of the Miliolida
It is a minute turbinate,
shell, with narrow umbilicus, its margin crenated. It is smooth, polished, white neatly blotched with pale rose.
The color of the shell is dead white (on the base a little glossy) on the thin
surface, through which ihe nacreous layer behind gleams.
Miliolana is a subclass established by Saidova, 1981 that comprises
members of the Miliolata from the Cornuspirida, Miliolida with agglutinated forms removed to the Miliamminana, and Soritida. Included are both free and attached forms, some coiled with two chambers per whorl arranged in different planes, others that are irregular or have serial chambers, and still others are fusiform with complex interiors, superficially resembling the Fusulinacea. The unifying character is their imperforate
Shells of "Hexaplex nigritus" can reach a length of . These large shells are black and white with black or dark brown stripes. The shell surface bears short spikes around the body whorl and spire. The aperture is
(Original description by Watson) The height of the shell attains 3.5 mm. The small shell has a depressedly conoidal shape that is sharply angulated, flattish on the base, sharply and deeply umbilicated. It is a little
, and flexuously ribbed.
Alveolinella is a genus of very elongate fusiform alveolinids from the Miocene to recent of the Indopacific with apertures on the leading face in multiple rows and aligned partitions (septula) dividing the primary chambers. Aveolinella are formanifera from the milioline family Alveolinidae and as miliolines have imperforate
walls to their tests.
Miliollata is a class wherein Foraminifera is regarded as a phylum that unites the
Miliolida, (subclass Miliolana Saidova, 1981) and siliceous Rzehakinidae (subclass Miliamminana Mikhalevich, 1980) based on similarities of their tests. Previously the Rzehakinidae were included in the Textulariina (Loeblich and Tappan, 1964) based on test wall composition rather than test form. The meaning of Miliolida is retained.
This shell is from a sea snail species "Turbinella pyrum" in the family Turbinellidae. This species is found living in the Indian Ocean and surrounding seas. The shell is
(i.e. the surface of the shell is strong, hard, shiny, and somewhat translucent, like porcelain).
Shell up to 32 mm in length, acuminate and slender. Color white, semitransparent at apex and
near body. Spire sides are straight while whorl sides are slightly convex, and sutures are simple and prominent. Protoconch has 2.5 to 3 glassy and conoidal whorls. Teleoconch has 8 to 8.5 whorls.
Rotalidia comprises a class of Foraminifera where Foraminifera is regarded as a phylum, (Kingdom Protista or Rhizaria, not Chromista) that unites Foraminifera that have tests composed of secreted lamellar calcium carbonate, optically radial or granular calcite, or aragonite; separating them from those with
, agglutinated, or microgranular, tests, or tests composed of organic compounds. Seven orders are included, the:
Triloculinella is a genus of Miliolacean forams with a fusiform to asymmetrically globular test. Inner chambers, one-half coil in length, are crypto-quinqueloculine to quinqueloculine in arrangement; The final three to five visible from the exterior. The aperture is an arch at the end of the final chamber, largely covered by a broad apertural flap, which distinguishes the genus from "Triloculina", "Quinqueloculina" and such, characterized by a more narrow tooth. The wall, as for all miliolids, is calcareous, imperforate,
Sigmoilinopsis is a genus of miliolid Foraminifera, with an ovate test, chambers one-half coil in length, arranged in rapidly changing planes in the early stage resulting in two spiralling series that appear sigmoid in section, gradually becoming planispiral in the adult. Walls are thick,
but enclosing a large quantity of agglutinated quartz particles, sponge spicules, and shell fragments; the aperture terminal, rounded, with a small tooth.
The adult test is ovoid to fusiform . Ontogeny goes through an early quinqueloculine stage immediately following the proloculus, followed in sequence by triloculine and biloculine stages and finally to an adult stage with completely enveloping chambes. Wall, calcareous, imperforate,
. Chambers with complete floors. Aperture in quinqueloculine and triloculine stages with a simple tooth. Aperture in adult stage, terminal, radially cribrate, with a convex trematophore (sieve plate) pierced by numerous irregular openings.
Sigmoilinita is a miliolid genus (Foraminifera) with an ovate to fusuform test that becomes flattened with growth. Chambers are tubular, one-half coil in length, at first added in a sigmoiline (S-shaped) series starting at slightly more than 180° apart. the angle gradually decreasing until the later whorls are planispiral. Chambers are numerous, the wall narrow. imperforate,
. The aperture at the end of the final chamber. may have a weakly developed tooth
Archaeological finds of Chinese pottery in the Middle East go back to the 8th century, starting with Chinese pottery of the Tang period (618-907). Remains of Tang period (618-907) ceramics have been found in Samarra and Ctesiphon in present-day Iraq, as well as in Nishapur in present-day Iran. These include
white wares from Northern Chinese kilns, celadon-glazed stoneware originating in the Yue kilns of Northern Zhejiang, and the splashed stoneware of Changsha kilns in Hunan Province.
Fischerinidae is a foraminiferal family now in the miliolid superfamily Cornuspiracea that comprises genera that can be free or attached, in which the proloculus is followed by an undivided tubular or spreading second chamber. Commonly, especially in free, i.e. unattached, forms the second chamber is looped around in coils. As diagnostic for the Miliolida the test wall is of imperphorate
calcite. The aperture, which is the avenue of egress and ingress for the protoplasm, is terminal; can be rounded or slitlike.
Shells of "Hexaplex radix" can reach a size of . These large, massive, heavy shells are globose or pear-shaped and very spyny, with a white surface and blackish-brown foliations and spiral elements. The body whorls have six to eleven varices. The aperture is large, broad, ovate and
white. The outer edges are strongly dentate. The siphonal canal is moderately long. The operculum is dark brown.
Ceramics industry was highly developed during Goryeo times. Production of a
stoneware with a fine bluish-green glaze (known as celadon) was centered in Jolla and reached its highest development in the twelfth century. The technology was originally imported from the Song China, but Korean potters developed a distinctive style that today is regarded as one of the greatest artistic achievements in the field. Ceramics were one of the major industrial exports during the eleventh and early twelfth centuries.
The test is free, chambers one-half coil in length, added in planes 120 deg. apart, as in "Triloculina". Tests are rounded to triangular in section; sutures depressed. As with other miliolid, the wall of the test is composed in imperforate,
calcite. The aperture is terminal, at the end of the final chamber, but instead of having a distinct tooth, as in "Triloculina", "Cruciloculina" develops as tri-radiate aperture in the young that becomes cruciform (X-shaped) to dendritic in the adult.
