Journal of Crustacean Biology      Jan 2019   [Refereed]
The calcification of the two valves of ostracodes in evolutionary history is poorly understood. Previous studies hypothesized that valve calcification has intensified with the development of a more complex hingement, independently of phylogeny. Th...

Marine micropaleontology   135 32-44   Sep 2017   [Refereed]
During the Paleocene, the marine plankton community recovered its diversity after a severe diversity loss at the Cretaceous/Paleogene (K/Pg) boundary. In general, changes in Paleocene deep-sea ostracode faunas are poorly understood. It is still un...

Quaternary Research      Sep 2017   [Refereed]
The Sea of Japan (also termed the East Sea) has a circulation system isolated from the Pacific Ocean and East China Sea. The East Asian winter monsoon drives the circulation system and cools the Tsushima Warm Current (TWC) to form the Japan Sea In...
Tatsuhiko Yamaguchi, Rie Honda, Hiroki Matsui, Hiroshi Nishi
Paleobiology   43(4) 407-424   Aug 2017   [Refereed]
Sexual dimorphism is thought to have evolved via selection on both sexes. Ostracodes display sexual shape dimorphism in adult valves; however, no previous studies have addressed temporal changes on evolutionary timescales or examined the relations...
Tatsuhiko Yamaguchi, Takeshi Terada and Yuki Morono
Paleontological Research   20(4) 296-301   Oct 2016   [Refereed]
A scanning electron microscope (SEM) is a very common instrument to observe fossil specimens. Although a low-vacuum SEM is now getting to be a common tool, still a conductive coating is required for observation of specimens at higher magnification...

Geobios   49(5) 407-422   Sep 2016   [Refereed]
Invertebrate fossils described from ancient hydrocarbon seep deposits represent diverse groups, e.g., brachiopods, mollusks, decapod crustaceans, worm tubes, and rare echinoderms, but the fossil record of ostracodes from hydrocarbon seep deposits ...
Tatsuhiko Yamaguchi, Richard D Norris
Geology   43(5) 443-446   May 2015   [Refereed]
Modern global change threatens alpine ecosystems by forcing species to migrate to higher elevations and potentially eliminating alpine habitat altogether. Here we show that an analogous restriction of suitable habitat operates on submarine mountai...

Zootaxa   3919(2) 306-326   Feb 2015   [Refereed]
The ostracode genus Bicornucythere (Ostracoda, Crustacea) is abundant in modern-day eutrophic marine bays, and is widely distributed in estuaries and inner bays throughout East Asia, including in China, Korea, Japan, and the Russian Far East. The ...

Proceedings of the Integrated Ocean Drilling Program, 346   342    Mar 2018   [Refereed]
At the present, typical North Atlantic Deep Water ostracod faunas are characterized by the dominance of Krithe species and the association with Henryhowella and Poseidonamicus. The fauna may have originated during the Eocene–Oligocene. Because the...

Proceedings of the Integrated Ocean Drilling Program, 346   346    Oct 2017   [Refereed]
Little is known about fossil ostracods from deep-sea drilling sites in the marginal sea bordered by the Eurasian continent, the Korean Peninsula, and the Japanese Islands. This report presents taxonomic descriptions for the Pliocene and early Plei...

Bulletin of Geological Survey of Japan   59(7-8) 369-384   Aug 2008   [Refereed]

Bulletin of the Mizunami Fossil Museum   -(30) 91-105   Dec 2006   [Refereed]
The uppermost Eocene–lowermost Oligocene Kishima Formation, containing abundant Mazean molluscan fauna, is distributed in the Karatsu Coalfield of Saga Prefecture. The formation yields at least 12 ostracode species from muddy sandstones. The fossi...
