Trilobite-constrained Ordovician Biogeography of China with Reference to Faunal Connections with Australia

Proceedings of the Linnean Society of New South Wales
Volume 129 (19 Mar 2008)

Abstract: All the plates and most of the terranes in China exhibit close biogeographic links and may have formed part of eastern Peri-Gondwana during the Ordovician. Synthetic analysis based largely on the platform/inner shelf trilobite faunas suggests that the Chinese eastern Peri-Gondwanan plates and terranes may have belonged to a single biogeographic province during the Tremadocian (Tremadoc) and late Katian-Hirnantian (Ashgill), but may be separated into two sub-provinces during the Floian-early Katian (Arenig-Caradoc): one consists of South China, Tarim and Annamia, and the other may include North China, Sibumasu, Southern Tibet, Tianshan-Beishan and possibly Hainan. However, the deep-water facies trilobites of the relevant Chinese geographic units had progressively become more unifi ed from the mid Darriwilian to early Katian (Llanvirn to Caradoc) before the sub-provinces eventually broke down by the late Katian (Ashgill). Australian Ordovician trilobite faunas had close affinities with most of the Chinese eastern Peri-Gondwanan plates and terranes, but closest biogeographic links were in particular with North China and Middle Tianshan-Beishan.
