Preface: The phylogeny, fossil record and ecological diversity of ostracod crustaceans

  title={Preface: The phylogeny, fossil record and ecological diversity of ostracod crustaceans},
  author={Noriyuki Ikeya and Akira Tsukagoshi and David J. Horne},
After more than two centuries of research, more than 65,000 living and fossil ostracod species have been described and studied, yet much remains to be learned about this ancient, widespread and diverse group of bivalved arthropods. Their higher classification and phylogeny are subjects of vigorous debate, as is their position in the broader picture of crustacean phylogeny. At the same time, major advances in our understanding of ostracod lineages and their relationships are resulting from the… 

The importance of lithographic limestones for revealing ontogenies in fossil crustaceans

A summary of the occurrences of crustacean fossils providing developmental information and a demonstration of the potential of the lithographic limestones in this context are presented.

Japan's earliest ostracods

Mesozoic, Cenozoic and especially Holocene ostracod faunas have been documented from Japan. Not surprisingly, considering the plate tectonic factors at play, very few ostracod faunas are known from

Studies on development in Euphilomedes ostracods: Embryology, nervous system development, and the genetics of sexually dimorphic eye development

The main events in Euphilomedes’ embryology are studied, focusing on cleavage and cell migration, and a visual staging scheme for their development is described.

Ostracodes and Gastropods of the Waucobi Lake Beds: Significance for Pliocene Environmental and Climate Conditions in the Eastern Sierra Nevada, California

The fossil record of lake strata typically provide a high resolution record of past ecosystems and environmental conditions. The faunal records of the Pliocene Waucobi Lake beds provide such an

Occurrence of Hemocyanin in Ostracod Crustaceans

Bayesian phylogenetic analyses showed that ostracod hemocyanin subunit diversity evolved independently from that of other crustaceans, with myodocopid and platycopid subunits forming distinct clades within those of the crustACEans.

Recent marine Ostracoda from East Indian shelf-slope sediments and their response to marine hydrodynamics

A total of 45 seafloor sediments procured from shelf-slope region off Chennai–Cuddalore in the Bay of Bengal and analyzed for ostracod population revealed the presence of 41 species in 30 genera.

Exceptionally preserved lacustrine ostracods from the Middle Miocene of Antarctica: implications for high-latitude palaeoenvironment at 77° south

The ostracods signal a high-latitude lake setting viable for benthic animal colonization prior to 14 Myr ago and support the notion of warmer, tundra-like environmental conditions persisting in the Dry Valleys until the Middle Miocene.

Ostracodology in time and space: looking back on fifteen International Symposia on Ostracoda, and the times in between

Fifteen International Symposia on Ostracoda (ISO) have been organized between 1963 and 2005, each of them followed by one or more proceedings volumes. In the present study, 906 titles presented at



Phylogeny and evolution of Loxoconcha (Ostracoda, Crustacea) species around Japan

The results of this study suggest that the differences in ecology may have had an impact on the late Cenozoic diversification around Japan.

Crustacean phylogeny inferred from 18S rDNA

Resolution concerning issues of higher-order crustacean phylogeny remains elusive even after years of thorough morphological and palaeontological scrutiny. Surprisingly, there is as yet no consensus

Evolutionary Biology and Ecology of Ostracoda

This set of papers supports the claim that ostracod studies are situated in all main evolutionary domains, according to the author's own research.

Ontogenetic change of distributional patterns of pore systems in Cythere species and its phylogenetic significance

The similarity and difference of the pore patterns, which are traceable until the last ontogenetic stage, can be used to determine phylogenetic relationships and were applied to the reconstruction of phylogeny of the eleven living and three extinct species of Cythere.

Appendages of the arthropod Kunmingella from the early Cambrian of China: Its bearing on the systematic position of the Bradoriida and the fossil record of the Ostracoda

It is demonstrated that this genus, and by implication other taxonomically allied bradoriids in general, are neither ostracode, crustacean s.str.

Functional morphology of Palaeozoic ostracods: phylogenetic implications

  • G. Becker
  • Geography, Environmental Science
  • 2004
The combination of soft anatomy, carapace architecture and behaviour (feeding techniques, brood care) provide evidence of a general body plan which appeared (at the latest) during the Ordovician and continuously evolved towards the anatomy of modern ostracods.

Molecular phylogeny of Ostracoda (Crustacea) inferred from 18S ribosomal DNA sequences: implication for its origin and diversification

The tree topology and the crustacean fossil record suggest that the lineage of podocopidans and platycopidans should have separately been established already in the Cambrian, although there is no ostracod fossil record in that time period.

Origin of the Ostracoda and their maxillopodan and hexapodan affinities

  • W. Newman
  • Geography, Environmental Science
  • 2004
If current interpretations of living ostracodan and fossil hexapodan body plans are largely correct, it can be hypothesized the Ostracoda are close to the ancestor of the Hexapoda, and if so they are convergent.

A revised classification of the higher taxa of the Ostracoda (Crustacea)

  • A. Liebau
  • Geography, Environmental Science
  • 2004
A new classification of the Ostracoda is outlined, focusing on palaeontological data from the literature of the last four decades, and the superorder Podocopomorpha is accepted as a mantle term for the ‘P-orders’ Palaeocopidas, Punciocopida, Platycopida and Podocipida.

The evolutionary history of Late Permian Darwinulocopina Sohn, 1988 (Ostracoda) from the Russian Plate

Evolutionary trends in Late Permian Darwinulocopina are summarised with reference to extensive collections from eastern European Russia, from the White Sea in the North to the Cis-Caspian in the
