Cyclostome bryozoans: Their use as paleoceanographic, paleoclimatologic and paleoenvironmental proxies throughout the cenozoic of southern Australia.

环口苔藓虫：它们在整个南澳大利亚新生代作为古海洋学、古气候学和古环境指标的使用。海洋演化的揭开在很大程度上依赖于化石的数据--古代海洋的地球化学性质的替代物。南澳大利亚拥有4500万年前冷水碳酸盐沉积的无与伦比的记录，因此也是全球古海洋学的记录。目前，在这些广泛的沉积物中唯一可用的替代品是腕足类和浮游有孔虫。然而，这些沉积物中含有大量的低镁方解石苔藓虫，特别是环口苔藓虫，可以用来替代。这项研究将利用现有的广泛的现代海洋和第三纪样本、数据库和切片，评估这种苔藓虫，并测试它们的有用性和可靠性。这种潜在的替代品将在全球范围内对过去500年的石灰岩有用。

Cyclostome bryozoans: Their use as paleoceanographic, paleoclimatologic and paleoenvironmental proxies throughout the cenozoic of southern Australia. The unravelling of ocean evolution relies largely on data from fossils - geochemical proxies of ancient oceans. Southern Australia contains an inrivalled 45 million-year old record of cool-water carbonate sedimentation and thus global paleoceanography. Currently, the only proxies available in these extensive sediments are brachiopods and planktic foraminfers. However, these sediments contain prolific low-magnesium calcite bryozoans, particularly cyclostomes, that could be used instead. This research will assess such bryozoans and test their usefulness and reliability, utilising existing extensive modern marine and Tertiary samples, data bases and sections. Such potential proxies would be globally useful for limestones from the last 500My.
