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

环孔苔藓虫：它们在整个南澳大利亚新生代作为古海洋学、古气候学和古环境代用物的用途。海洋进化的解开很大程度上依赖于化石数据——古代海洋的地球化学代用物。南澳大利亚拥有无与伦比的4500万年前的冷水碳酸盐沉积记录，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，唯一可用的代用物是腕足类和浮游有孔虫。然而，这些沉积物含有丰富的低镁方解石苔藓虫，特别是环口虫，可以用来代替。这项研究将利用现有的广泛的现代海洋和第三纪标本、数据库和剖面，评估这些苔藓虫并测试它们的有用性和可靠性。这些潜在的代用物将对过去500年的石灰石在全球范围内有用。

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.
