This Project will refine a national biostratigraphic framework integrating growing understanding about the history of Australia's unique mammals, climate change and geological events. Increasing precision in correlating Australia's phylogenetic, palaeoecological and palaeoclimatological events will clarify how these act synergistically to change environments and biodiversity. Increased precision in the biostratigraphic framework will also serve evolutionary genetics which needs age data to calculate molecular rates of divergence, economic geologists needing to know the age of Cainozoic sediments, biologists trying to understand the origins and nature of biodiversity and conservationists using divergence dates and relative branch lengths to help determine conservation priorities.

该项目将完善国家生物地层框架，整合对澳大利亚独特哺乳动物历史、气候变化和地质事件的日益了解。在澳大利亚的系统发育，古生态和古气候事件的相关性越来越精确，将澄清这些如何协同作用，以改变环境和生物多样性。生物地层学框架的精确度提高也将有助于进化遗传学，因为进化遗传学需要年龄数据来计算分子的分歧率，经济地质学家需要知道新生代沉积物的年龄，生物学家试图了解生物多样性的起源和性质，保护主义者使用分歧日期和相对分支长度来帮助确定保护优先级。
