"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 (Toarcian) of France (Causes, 44.3° N, 3.3° E); the early middle Middle Jurassic (Bajocian) of Germany (Sengenthal); and the very late Middle Jurassic (Callovian) of India (the Gadhada Sandstone Member and the Chari Formation, 23.5° N, 70.5° E).
