A Standard Biostratigraphic Sequence for the Devonian of Western North America

美国西部泥盆纪的拟议研究 涉及三大领域的奋进。 1.腕足动物系统学： 尤其是志留纪-泥盆纪的腕足类， 家庭，和下属水平，他们的范围事件， 与编写《联合国海洋法公约》有关的地理意义 修订版的腕足动物手册。 2.中国大陆中部腕足类和牙形石生物地层 弗拉斯期-法门期泥盆纪和牙形石生物地层 边界 在这些层序中，大盆地的沉积历史是 正在调查的重点是海平面上升事件的加深 （中泥盆世）和台地暴露（上泥盆世）。 3. 上泥盆统动物群序列的调查， 强调腕足动物为主的群落和综合区 与牙形石分区计划，将继续建立在已公布的 研究表明，早泥盆世和中泥盆世 顺序

Proposed research in the Devonian of the western United States involves three broad areas of endeavor. 1. Brachiopod systematics: especially Siluro-Devonian spiriferid brachiopods at the genus, family, and subordinal levels, their range events, and biogeographical significance, in connection with preparation of the revised edition of the Brachiopod Treatise. 2. Brachiopod and conodont biostratigraphy of the Middle Devonian and conodont biostratigraphy across the Frasnian-Famennian boundary. In these sequences Great Basin depositional history is being investigated with a focus on eustatic events of deepening (Middle Devonian) and platform exposure (Upper Devonian). 3. Investigation of the Upper Devonian faunal sequence, with emphasis on brachiopod-dominated communities and zones integrated with the conodont zonal scheme, will continue to build on published research that has made known the Lower and Middle Devonian sequence.
