Dacryomya


Dacryomya, or the pointed nutclam is an extinct genus of small-sized saltwater clams, marine bivalve molluscs in the nutclam family Nuculanidae. The size and shape of the shells of species in this genus are reminiscent of broad apple pips.

Distribution

Dacryomya lived during the Lower and Middle Jurassic, possibly throughout the Tethys Faunal Province. Fossils of D. lacryma are known from the very late Lower Jurassic of France ; the early middle Middle Jurassic of Germany ; and the very late Middle Jurassic of India.

Habitat

The fossil locations cited were open shallow subtidal areas, where this mollusc lived as a facultatively mobile infaunal deposit feeder-suspension feeder.
