Patterns of Dinosaur Abundance Through Time in Facies of the Hell Creek Formation

9304513名法斯托夫斯基PI将对密尔沃基公共博物馆收集的化石材料进行统计数据分析，该项目是由密尔沃基公共博物馆收集的，该项目名为挖掘恐龙。拟议的分析将检验这样一个假设，即在白垩纪的最后220万年里，恐龙的多样性和丰富度逐渐减少。这项研究还将解决确定灭绝速度的一般问题，包括农艺问题、采样和保存偏差以及(古)生态控制。

9304513 Fastovsky PIs will conduct a statistical data analysis of fossil material collected by the Milwaukee Public Museum "Dig a Dinosaur" program. Proposed analyses will test the hypothesis that dinosaurs dwindled gradually in diversity and abundance during the last 2.2 million years of the Cretaceous. This research will also address the general problem of determining rate of extinction, including taphonomic issues, sampling and preservation biases, and (paleo)ecologic controls.
