The Ventrolaminidae are a family of benthic Foraminifera included in the Involutinida, now part of the subclass Spirillinana, class Spirillinata.[1]
Tests of the Ventrolaminidae are lenticular, planispiral, or a low trochospiral with multiple chambers in a rapidly enlarging whorl. The wall is calcareous in two layers. The inner one is microgranular, the outer hyaline glassy).[2]
Two genera are included, Archaeosepta and Protopeneroplis. Loeblich and Tappan included Protopeneroplis (or Ventrolamina, in the Involutinidae in the Treatise Part C, 1964. Archaeosepta was added hence, in 1970.
