Funds are provided to complete taphonomic and paleobiologic work on a series of highly significant bonebeds containing the largest concentration of Late Cretaceous dinosaurs and associated vertebrates found in either ancient polar region. These paleontologic studies will be integrated with the development of a sequence stratigraphic framework, including a description of fossil soils and fluvial sedimentology, to provide comprehensive documentation of an ancient Arctic terrestrial/coastal ecosystem during a "greenhouse" period in Earth's history by: 1) testing hypotheses from previous paleobiologic, taphonomic, paleobiogeographic and paleoclimatic work regarding the ancient arctic terrestrial ecosystem; 2) establishing high resolution litho- and chronostratigraphic framework for the dinosaur-rich succession within the Prince Creek Formation; 3) integrating multidisciplinary data to produce a much-needed framework for a greater understanding of the paleoenvironments within which abundant, diverse, and long-standing paleo-arctic dinosaur populations thrived; and 4) better understanding Earth history at a critical time of biological diversity, mass extinction and climate change in the ancient arctic.

提供的资金用于完成对一系列非常重要的骨床的挖掘和古生物学工作，这些骨床中包含了在这两个古老极地地区发现的最集中的晚白垩世恐龙和相关脊椎动物。这些古生物学研究将与层序地层学框架的发展相结合，包括对化石土壤和河流沉积学的描述，以通过以下方式提供地球历史上“温室”时期古代北极陆地/沿海生态系统的全面文献：1)测试先前关于古代北极陆地生态系统的古生物、墓葬、古地理和古气候工作的假说；2)为太子溪组内富含恐龙的演替建立高分辨率的岩石和年代地层框架；3)整合多学科数据，以产生一个迫切需要的框架，以更好地了解丰富、多样化和长期存在的古北极恐龙种群内的古环境；以及4)在古代北极生物多样性、大规模灭绝和气候变化的关键时刻，更好地理解地球历史。
