Though the exterior is more uniform than in most groups of Crustacea, the bivalved shell or carapace may be strongly calcified and diversely sculptured (fig.
The bivalved carapace has a jointed rostrum, and covers only the front part of the body, to which it is only attached quite in front, the valve-like sides being under control of an adductor muscle.

The fossils of the undoubted Glacial deposits are principally shells, which are found in great numbers in certain localities, sometimes with Foraminifera, the bivalved cases of Ostracode Crustaceans, &c.
The Water-fleas (Ostracoaa) are extremely abundant in the Carboniferous rocks, whole strata being often made up of little else than the little bivalved shells of these Crustaceans.
Besides the little bivalved Ostracoda--which here are occasionally found of the size of beans--and various Phyllopods of different kinds, we have an abundance of Trilobites.
The carapace, as in the Conchostraca, forms a bivalved shell, but does not enclose the head.

In this family the two valves are attached to each other by their free edges, just as in the bivalved Mollusca and Diatoms; and these edges may either be smooth (Conchasmida, Pl.
The #Phaeoconchia# are distinguished from all other Radiolaria by the possession of a bivalved shell like that of the Conchifera; the two valves of this Conchoid skeleton must be distinguished as dorsal and ventral, as in the Brachiopoda (Pls.
In the peculiar bivalved #Phaeoconchia#, on the other hand, the basal pole with the cannopyle is directed upwards; as also in the Challengerida and Tuscarorida.
The bivalved shell of the Ostracoda gives to this group of animals an external appearance very different from that of the trilobites, but the few appendages, though highly modified, are directly comparable.

Many of the Cambrian branchiopods had developed a bivalved carapace, though not so large a one as that of the primitive Leptostraca.
The division will be probably effected in the frontal plane, so that each half of the bisected capsule gets one nucleus and one valve, and the other valve becomes newly formed (in a way similar to that in the bivalved Diatomaceae).
Spongy framework of the bivalved mantle rather loose, not nearly so thick and dense as in the preceding species.
Hollow tubes, arising from the galea of both valves, dichotomously branched; the branches anastomose and form an outerbivalved lattice-mantle.
The central capsule fills up the cavity of the bivalved shell almost entirely, and the voluminous dark phaeodium envelops both to such an extent that the shell and the enclosed capsule are often hidden in it completely.
The lateral margins of the two hemispherical valves are smooth, without teeth, and catch one into the other like the two valves of a Diatom, or the two halves of a bivalved box.
Spongy framework of the spherical bivalved mantle very dense and thick, produced by very numerous, irregular anastomoses of the lateral and terminal branches, which arise from the hollow tubes.
