The project aims to precisely document and synthesize the biotic, sedimentologic, and geochronologic signals in the Cambrian Series 2–Series 3 boundary interval for the most significant and little studied Cambrian continents. It is believed that a significant refinement in correlation can be achieved by the taxonomic investigation of yet undescribed and imperfectly studied skeletal fossils and the correlation of the biotic succession of these remains with sea-level fluctuations and its eustatic and epeirogenic characters in various regions of the Cambrian continents. The three-year project will allow a focus on the biota, the composition of which is to be detailed to reveal evolutionary changes and facies relationships for the studied interval. Previously undescribed skeletal metazoan fossils (primarily trilobites as the principal biostratigraphic indicators) from Morocco, Israel/Jordan, Turkey, the Franconian Forest, North Greenland, and Newfoundland will be systematically studied and described. The final objective is a global synthesis of faunal, sea-level, and climate change on tropical and temperate paleocontinents (i.e., West Gondwana, Avalonia, Baltica, Laurentia, and the Yangtze Platform) for one of the most dramatic intervals in life history. This synthesis will allow reevaluation and resolution of the highly divergent views for biostratigraphic intercontinental correlation of this interval and is a major contribution to the global subdivision project of the ISCS.

该项目旨在精确记录和综合寒武纪系列2-系列3边界间隔中最重要和研究较少的寒武纪大陆的生物，沉积学和地质年代学信号。人们相信，通过对尚未描述和研究不完善的骨骼化石进行分类学调查，并将这些遗骸的生物演替与寒武纪大陆不同地区的海平面波动及其海平面升降和造陆特征相关联，可以实现相关性的重大改进。这个为期三年的项目将重点关注生物群，其组成将被详细说明，以揭示所研究的间隔的演化变化和相关系。来自摩洛哥、以色列/约旦、土耳其、弗兰肯森林、北格陵兰和纽芬兰的以前未描述的骨骼后生动物化石（主要是三叶虫作为主要的生物地层学指标）将被系统地研究和描述。最终目标是对热带和温带古大陆（即，西冈瓦纳，阿瓦隆尼亚，波罗的海，劳伦提斯和扬子地台）的生命史上最戏剧性的间隔之一。这种综合将允许重新评估和解决这个区间的生物地层洲际对比的高度分歧的观点，是对国际海底科学系统全球细分项目的重大贡献。
