See text Pelagiellidae is an extinct family of Paleozoic fossil 'snails'.

Some material assigned to this taxon represents gastropod molluscs, but some chaeta-bearing specimens first assigned to Pelagiella (now Pseudopelagiella) are perhaps better interpreted as tube-bearing annelid worms.

[3] Aragonite, with various microstructures - details in reference [4] The taxonomy of the Gastropoda by Bouchet & Rocroi, 2005[5] categorizes Pelagiellidae in the superfamilia Pelagielloidea within the Paleozoic molluscs of uncertain systematic position.
