| Abstract: | Leptocoeliid brachiopods from the Early Devonian Baruntehua Formation of Dong Ujimqin Qi, northeastern Inner Mongolia were assigned to Leptocoelia by Su (1976) and Zhang(1983), and subsequently to Pacificocoelia by Hou & Boucot (1990). Transverse serial sections of Pacificocoelia sinica are illustrated hère, for the first time, based on topotype specimens. The known geographic range o Pacificocoelia is from northern China, North America, South America and Kazakhstan (Eastern Americas Realm and also occurs in east-central Asia). Atlanticocoelia is regarded hère as a junior synonym of Pacificocoelia. |
