摘要
During the last two decades research on the Devonian period was part of some successful IGCP projects, such as IGCP 216 """"""""Global biological events in Earth history"""""""" (led by O.H. Walliser), IGCP 335 """"""""Biotic recoveries from mass extinctions"""""""" (led by D.H.Erwin and E.G. Kauffman), and IGCP 421 """"""""North Gondwanan Mid-Palaeozoic bioevent /biogeography patterns in relation to crustal dynamics"""""""" (led by R. Feist and J.A. Talent）.
