This study includes the following: 1. Completion of the series of worldwide Silurian Correlation charts: Continental Europe and Northern Asia (Asiatic Russia, Mongolia, Korea, Japan). 2. Obtaining biogeographically critical Silurian and Devonian brachipod collections from southern Thailand, northwestern Saudi Arabia, northern Chile and adjacent Argentina, to fill in critical blanks and establish better relations between large parts of the World. To further investigate the implications of the newly discovered terrestrial biogeography of the higher land plants (using spore tetrads) for the Llanvirn-Llandovery interval of the Ordovician and Silurian, and compare and contrast it with the biogeography of the associated marine environments. To further extend global, studies of post-Ibexian brachipod biogeography for the Ordovician at the generic level. Description of biogeographically critical Upper Silurian brachipods from Iran will also be carried out. 3. Completion for publication of the global studies involved in Project Ecostratigraphy. 4. Gathering information on the Ibexian-Whiterockian boundary interval, which is one of the major times of both extinction and subsequent adaptive radiation in the marine environment, and about the minor extinction event that occurred in the earlier Wenlockian for much of the World. 5. Completing the Treatise on Invertebrate Paleontology assignment, as part of the brachiopod volume revision, on the pentameroids and Paleozoic terebratuloids.

这项研究包括以下内容： 1. 世界志留系对比系列的完成 图表：欧洲大陆和北方亚洲（亚洲俄罗斯， 蒙古、韩国、日本）。 2. 获得地理学上的关键志留系和泥盆纪 来自泰国南部，沙特西北部的腕足动物 阿拉伯半岛、北方智利和邻近的阿根廷，以填补关键的 空白和建立更好的关系之间的大部分 世界 为了进一步研究新的 发现了高等陆地植物的地理分布 （使用孢子四分体）的Llanvirn-Llandovery间隔 奥陶系和志留系，并与 相关海洋环境的地理学。 进一步 扩大全球范围，对后Ibexian腕足动物的研究， 奥陶纪在属的层次上。 描述 来自伊朗的上志留世腕足类化石， 也要执行。 3. 完成有关全球研究报告的出版工作， 生态地层学项目 4. 收集有关伊贝先-怀特罗克阶边界的资料 间隔，这是两个灭绝和 随后在海洋环境中的适应性辐射， 发生在温洛克纪早期的小灭绝事件 对于世界上的大部分地区。 5. 完成对无脊椎动物古生物学的研究 分配，作为腕足动物体积修订的一部分， 五角体和古生代圆柱体。
