摘要

The recent discovery of mummified Dacrycarpus remains from the Miocene Erzitang Formation of the Guiping Basin,Guangxi,southern China,essentially contests our concepts of floristic exchange between Australia and China.East Asia has several biodiversity hotpots and is a key region for understanding the origin and evolution of the biodiversity in the Northern Hemisphere [1].Most Gondwanan elements in East Asia are those formerly distributed across much wide areas in the Southern Hemisphere,but their modern distributions are the results of complex geological and climatic changes.Understanding the biogeographical history of Gondwanan taxa,and the mechanism underpinning their current distributions,help in understanding and conserving extant biodiversity.
