Podocopida Sars, 1866. Ostracods, or ostracodes, are a class of the Crustacea (class Ostracoda ), sometimes known as seed shrimp. Some 33,000 species (only 13,000 of which are extant) have been identified, [2] grouped into 7 valid orders. [2] They are small crustaceans, typically around 1 ...

A total of 160 specific names are included. Of these, 154 are taxonomically accepted names. At present, the richest province with more than 53 species of ostracods is Qinghai, followed by Yunnan …Succession of late Pleistocene and Holocene ostracode assemblages in a transgressive environment: A study at a coastal locality of the southern Baltic Sea (Germany). Palaeogeography, Palaeoclimatology, Palaeoecology, Vol. 264, Issue. 3-4, p. 318.Eighty-one ostracode taxa were identified in 81 samples. Changes in ostracode faunas in space and time provide information that enabled us to reconstruct a detailed paleobiogeography of the Bay.the Cherty-ostracode Unit of this member, and (c) to determine relationships between the organic geochemical composition of the Cherty-ostracode Unit of the Upper Limestone Member and both the various studied facies and fifth-order cyclicity. This paper is also a contribution to the ongoing study of restricted carbonate platform facies.

The Ostracoda are one of the most diverse arthropod groups alive today; they also have a tremendous fossil record. Because of their widespread environmental distributions, small size and carbonate shell, they have become extremely useful biostratigraphic and paleoenvironmental proxy indicators, particularly in nonmarine environments. Ostracode community composition of springs differed from all other sampled habitats, which was also reflected in CCA analyses. Our data indicated that the ostracode fauna of western Mongolia shows a high response to calcium content, alkalinity, salinity, temperature, nutrients, and altitude. Species composition and diversity seem to be ...Changes in ostracode assemblages through time can provide such records as ostracode species are sensitive to changes in their local environments. Before they can be used to indicate past environments, however, is it necessary to understand how distributions of assemblages change across environmental gradients. To that end, thirty-two lakes on ... ….

Jan 1, 1999 · The profiles express ostracode tolerance of environmental parameters such as salinity or currents. Tolerance of a wide range of values is taken to indicate shallow water because shallow environments are conducive to thermal variability, short-term water residence, and the development of currents from wind-driven waves. Here we analyzed the late Paleocene-early Eocene ostracode species from Deep Sea Drilling Project (DSDP) Site 401 (47°25.650′N, 8°46.618′W, 2495 m water depth; Fig. 1) in the Bay of Biscay, North Atlantic.Planktonic foraminifer and calcareous nannofossil biostratigraphy has been described for this site (Pardo et al., 1997, Tremolada and Bralower, 2004), as well as the extinction of ...

Cluster analysis revealed three water depth ranges in the lake of importance to ostracode distribution: 1) littoral zone (0.1-3 m), 2) water depths from the base of the littoral zone to the base of the thermocline (3-40 m), and 3) water depths below the thermocline (40-160 m).Thirty species of 10 ostracod genera were identified from 440 fossil specimens isolated through the hot acetolysis of the rock samples collected across the Permian-Triassic boundary at Chongyang section.
