Trilobites and biofacies of the Ordovician Pagoda Formation, Donggongsi of Zunyi, Guizhou Province, China
Published online by Cambridge University Press: 03 November 2011
Abstract
Twenty-one trilobite species belonging to 18 genera are described from the measured section of the Pagoda Formation (Caradoc) at Donggongsi, Zunyi, Guizhou Province, China. The fauna is numerically dominated by the hammatocnemid Ovalocephalus and remopleuridid Dislobosaspis (gen. nov.), and the Ovalocephalus–Dislobosaspis Biofacies is established to represent a shallow outer-shelf trilobite association. The lithofacies and trilobite taphonomy indicate a comparatively quiet and undisturbed depositional environment. Trilobites exhibit strong SE Asian affinities and formed part of the Peri-Gondwana fauna. They are closely related to those of South- Central Europe but show some Baltoscandian aspects.
