†Archinacellidae is an extinct family of paleozoic molluscs of uncertain position (Gastropoda or Monoplacophora).

Description

These are cap-shaped fossil shells.

Taxonomy

The taxonomy of the Gastropoda by Bouchet & Rocroi, 2005[3] categorizes Archinacellidae in the superfamilia Archinacelloidea within the Paleozoic molluscs of uncertain systematic position. This family has no subfamilies.

Genera

Genera in the family Archinacellidae include:

  • Archinacella Ulrich & Scofield, 1897[4] – type genus of the family Archinacellidae
    • Archinacella powersi Ulrich & Scofield, 1897 – type species
    • Archinacella instabilis (Billings, 1865)[5]
  • Barrandicella Peel & Horný, 1999
  • Barrandicellopsis Horný, 2000[6]
    • Barrandicellopsis ovata – synonym: Archinacella ovata Barrande in Perner, 1903 – Archinacella ovata var. elevata Barrande in Perner, 1903 – type species, Middle Ordovician from Bohemia
    • Barrandicellopsis extenuata – synonym: Orthonychia extenuata Barrande in Perner, 1903 – probably belongs to genus Barrandicellopsis, Middle Ordovician from Bohemia[6]
