Until now, however, most studies of either extant or fossil ostracodes are still confined to analyses of the species composition. Little is known about the spatial distribution of extant ostracode in regards to the population age structure.the most atypical of all of the ostracode groups which have traditionally been assigned to the Myodocopa and their true taxonomic position may well lie elsewhere” (Siveter & Vannier 1990, p.19). That some Silurian myodocopes probably had pelagic lifestyles was proposed in a paper interpreting the habitats and modes of lifeThe ostracode response to oceanographic changes during the Paleocene-Eocene thermal maximum (PETM, ca. 55 Ma) is largely unknown. The Gebel Duwi section (Egypt) provides a detailed ostracode record across the PETM in a middle neritic setting. Quantitative analysis of this record reveals two significant results.Ostracods are by far the most abundant fossil arthropods. They are collected for many purposes and applications, such as palaeoenvironmental and palaeoecological analysis, dating and correlation of rock sequences, reconstructing past geographies, and for taxonomic and evolutionary studies. By virtue of their small size and calcified bivalve ...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 relationship between Mg/Ca ratio in ostracode valve and temperature has primarily been modeled as a simple temperature-dependant partition coefficient between valve and ambient water (e.g., De Deckker et al 1999, Engstrom and Nelson 1991, Xia et al 1997).
