- Abstract
A bivalve fauna of Early Ordovician (late Arenig) age is described from the Hsiangyang Formation of the eastern part of West Yunnan, China. The fauna contains elements in common with Early Ordovician faunas of southern Gondwanan areas such as the Montagne Noire and Morocco and with those of Avalonia, together with several previously undescribed taxa. The following taxa are new:Biseriodonta simplexgen. et sp. nov.;Glyptarca sinensissp. nov.;Trigonoglyptarca magnagen. et sp. nov.;Erhaiconcha xiangyangensisgen. et sp. nov.;Fasciculodonta impressagen. et sp. nov.;Yunnanoredonia laevisgen. et sp. nov.;Daliellagen. nov.;Goniophorina(Goniophorina)contractasp. nov.;Haidongoconcha radialisgen. et sp. nov.;Eopterinea aequiconchagen. et sp. nov. The bivalve fauna includes the most diverse glyptarcid fauna and the earliest nuculanid and paracyclid known hitherto. Eastern West Yunnan belonged to the Indochina terrane and it is concluded that the bivalve fauna represents a high-latitude assemblage and that the Indochina terrane should be considered a component part of the Peri-Gondwanan continent in the Ordovician; its bivalve faunas contrast with those of neighbouring terranes which have affinities with those of lower latitudes.
