Original Description
Type of wall: Muricate, with a tendency for concentration of the muricae around the periphery and umbilical region and possessing smooth areas on the spiral side.

Test morphology: Low trochospiral, generally lobulate or petaloid in outline, with concentration of bladed muricae around the periphery forming a discontinuous muricocarina. Four to eight chambers in the final whorl; aperture umbilical-extraumbilical or wholly extraumbilical

Etymology: Similar to Morozovella.

Extra details from original publication
Distinguishing features — Morozovelloides n. gen. is highly convergent in morphology with some true Morozovella. It is considered in this work to be derived from Acarinina.

Discussion — The new genus accommodates several lower-middle Eocene species that have generally been placed in Morozovella in recent years, but which are believed to have evolved from Acarinina. The concept of Morozovelloides was developed in discussions with R.D. Norris (pers. comm., 2001).

Stratigraphic range — Restricted to the middle Eocene, Zones E7-E13.
