贵州关岭生物群研究的进展和存在问题(代序)

Study of the Guanling biota in Guizhou:progress and problems

德国被誉为三叠系的故乡,因为三叠系这个术语来自德国的日尔曼盆地,其中三叠统壳灰岩素有化石库之称。然而,关岭生物群的发现和在生物群的时代、组合特征、产出层位、分布以及形成环境等方面研究的进展表明:关岭生物群堪称世界上独一无二的化石库或化石矿床,其化石保存之完美、类型之多样、数量之多,远远优于德国的壳灰岩。对这个珍稀生物群的综合研究不仅为创新海生爬行动物、海百合和软骨鱼等化石的分类、演化、古生态和古生物地理分区的理论提供了丰富的素材,而且对于解决与此有关的重大问题、建立中国甚至全球拉丁阶和卡尼阶界线层型剖面、发展生物超常规保存及埋藏环境理论和重建“三叠纪公园”均具有重要意义。

Germany is known as the native place of the Triassic System since the term of'Triassic' is from the Germatic Basin.The Germanic well-known Middle Triassic(Anisian)Muschelkalk is always known as“Fossillagersttten”.However,the discovery of the Guanling biota in the Guanling area,Guizhou Province,SW China,and the advances in the study of the assemblage,age,horizon,distribution and formation environment of the biota indicate that the Guanling biota may be rated as a unique Late Triassic“Fossillagersttten”.This“Fossillagersttten”is much superior to the well-known Muschelkalk“Fossil-lagersttten”in fossil abundance,diversity and preservation and very seldom seen in the world.The com-bined bio-,eco-,sequence-and chemo-stratigraphic studies of this valuable and rare biota not only provide abundant materials for exploring the taxonomy ,evolution,paleoecology and biogeographic provin-cialism of marine reptiles,crinoids,clasmorbranch ichthyolids etc.,but also have great significance for ex-plaining some relevant problems ,establishing regional and even global Ladinian /Canian boundary stratotype,developing the theory of unusual preservation and taphocoenosis and reconstruction of the“Triassic Park”.
