**Dacryoconarida** is an extinct subclass of free living animals from the [Tentaculita](/source/Tentaculita) class, which were common in the Devonian oceans (Fisher, 1962). Dacryoconarids have a subspherical, drop- or tear-shaped embryonic chamber (Farsan 2005). The phylogenetic affinities of tentaculites are not fully resolved; they have often been placed among [molluscs](/source/Molluscs), but recent microstructural analyses place them among the [Lophophorata](/source/Lophophorata). Their fossils are known from Devonian rocks of Australia, Asia, Europe, North Africa and North America.
