The shell in the Discosoridae is conical, expanding variably with respect to genus.

Curvature tends to be slight with the ventral or siphuncular side slightly concave in profile (the endogastric condition), and the opposite dorsal side arched or convex in profile (another endogastric condition).

The siphuncle is composed of broadly rounded segments the increase rapidly in size toward the aperture, with growth.

Endocones are formed by overlapping parietal deposits that line in inner side of the siphuncle in the apical part of the shell.

Most of the information regarding comes from isolated siphuncles The Discosoridae are thought to be derived from the Lowoceratidae, a small family of variably exogastric discosorids, probably from Lowoceras the straighter of the two.
