Abstract: | In podocopid ostracods, the “hingement”, with teeth/sockets or crenulations, is developed along the attached dorsal margin of the carapace. Dual calcified lamellae, called “duplicatures” are also developed along the free margin. However, the terminology of these marginal areas is often confused by many ostracodologists because of their differing interpretations and viewpoints. In this study, the marginal areas of the carapace were observed in detail, using the transmission (TEM) and scanning (SEM) electron microscopes. Consequently, the terminology of the marginal areas has been revised. The homology between attached and free margins and the structural differences of duplicatures, for some taxa are also discussed. |
