We present a subjective list of the Recent, free-living, non-marine ostracods species and genera of the world, with their distribution in the large zoogeographical regions, as well as a list of genera in their present hierarchical taxonomic position. Based on the recognised synonymies, there are at present about 2090 species in c. 209 genera.Converting the ostracode Mg/Ca ratios to temperature 11 (Extended Data), the MBE shift equates to a rise in bottom temperatures in the AIW layers from near 0 °C to as much as 3–5 °C.INTRODUCTION. The Indo-Australian Archipelago (IAA), also known as the Coral Triangle, a hotspot in the Indo-West Pacific region (IWP), is known as the area of highest marine biodiversity for various taxa (Paulay, 1997; Hoeksema, 2007; Tittensor et al., 2010; Bellwood, 2012; Jablonski et al., 2013).Fossil (larger benthic foraminifera, ostracods, corals) and molecular (gastropods) evidence ...

Analysis of thorium and ostracode shell abundance records from the Songliao Basin reveal evidence for two chaotic secular resonance transitions in the orbital motions of Earth and Mars from 85.2 Ma to 91.55 Ma. The evidence validates similar observations in western North American marine stratigraphy.The meaning of OSTRACOD is any of a subclass (Ostracoda) of very small aquatic crustaceans that have the body enclosed in a bivalve carapace, the body segmentation obscured, the abdomen rudimentary, and only seven pairs of appendages.Ocean Drilling Program (ODP) Holes 980 B and C, Feni Drift at the eastern slope of the Rockall Plateau, eastern North Atlantic, were examined for late Quaternary deep-sea ostracode taxonomy. Nineteen genera and 32 species were examined and (re-)illustrated with high-resolution scanning electron microscopy images. The ostracode values mostly coincide with the ranges . of the equilibrium calcites from June to December. During the first half of the year, the ostracode val-The giant sperm of ostracods are exceptional in as far as they are considered to have originated only once some 100 million years ago and have been retained since then, which stands in contrast to ...

The carbonate valves of ostracodes provide excellent material for oxygen ...We would like to thank the Canadian Museum of Nature for generously granting permission for the Delorme Ostracode Dataset to be shared through the Neotoma paleoecology database.
