Brachiopod, mollusk, trilobite, ostracod, bryozoan, graptolite and stromatoporoid fossils are especially common. Carbonita is an extinct genus of nonmarine ostracod crustaceans that lived during the Carboniferous period. Limnocythere is a genus of ostracod crustaceans in the family Limnocytheridae. Based on the ostracod and charophyte assemblages of the Iren Dabasu Formation, Itterbeeck et al. Most of the fossil examples of ostracod come from the preserved carapaces, or feeding appendages. The ostracod assemblages of this formation indicate a neo-Algoas age (local time scale). Vargula tsujii is a bioluminescent cypridinid ostracod found in southern California. Neocyprideis timorensis is a species of Indo-Pacific ostracod that has existed since the Miocene. Its age, based on the ostracod assemblages, is Hauterivian to Aptian. Two cladoceran, two ostracod and one testate amoeba species were originally discovered in Licancabur Lake. The diet may include insects, mainly larvae; snails, and Ostracod crustaceans. Similar to another ancient lake, Tanganyika, Baikal is a center for ostracod diversity. Ostracod fossils were used to establish its age. The ostracod "Sclerocypris zelaznyi" was named after him. Ostracod species identified in Navidad Formation numbered 28 by 1978.
