描述
China is richly endowed with Cambrian strata yielding some of the best-preserved fossils known anywhere in the world. The trilobites are most important element in the fauna, and of scientific relevance. The polymerid trilobite faunas of northwestern Human are remarkable for their diversity and excellence of preservation. Many of them belong to genera confined to China or to its palaeogeographic neighbours. The detailed work on the trilobites is placed in the wider context of biostratigraphy and correlation, which should be of interest to all those concerned with Cambrian geology. A refinement of the biostratigraphic zones based on the ranges of trilobite species will have implications for those currently seeking to increase the precision in international correlation of subdivisions within the Cambrian. Careful new work, of which this paper is an excellent example, is a more valuable contribution than anything else in this endeavour Provides general geologic information concerning the Huaqiao Formation of the northwestern Hunan, lithostratigraphic data, and biostratigraphic zonation. This two-volume set also contains systematic treatments of ptychopariids, eodiscids, and trilobites of uncertain affinity. V. 1. Corynexochida, Lichida, And Asaphida -- V. 2. Ptychopariida, Eodiscida, And Undetermined Forms. Peng Shanchi, Loren E. Babcock, Lin Huanling. Reprint Of Ed. Published In 2004. Includes Bibliographical References And Indexes.

备用描述
China is richly endowed with Cambrian strata yielding some of the best-preserved fossils known anywhere in the world. The trilobites are most important element in the fauna, and of scientific relevance for several reasons. First, they are of regional importance in the precise correlation of strata, and are of primary use in characterising mappable formations. Second, some of the species are widespread internationally, and these permit the placing of Chinese stratigraphical schemes within the global chronostratigraphy. Thirdly, the variety, relationships and endemicity of the faunas contributes to the broad questions of how evolution proceeded in the Cambrian, and is relevant to debates about whether special conditions applied at the early stage of the Phanerozoic radiation. Volume 1 of this set contains general geologic information concerning the Huaqiao Formation of the northwestern Hunan, lithostratigraphic data, biostratigraphic zonation, detailed description of three stratigraphic sections, and the systematic of corynexochid, lichid, and as aphid trilobites. Volume 2 contains systematic treatments of ptychopariids, eodiscids, trilobites of uncertain affinity, and some undertermined sclerites. In both volumes, considerable effort was made to reillustrate type material of many previously described taxa. In some older literature, illustrations were not always reproduced well, so the new illustrations should help to clarify taxonomic concepts. * Provides a detailed documentation of 196 polymerid triobites from Huaqiao Formation of northwestern Hunan, including a large number of new genera and species * Includes high-quality photographs and illustrations throughout; From 500 to 570 million years ago
