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.

Fastovsky pi将对密尔沃基公共博物馆“挖掘恐龙”项目收集的化石材料进行统计数据分析。拟议的分析将检验这样一种假设，即恐龙的多样性和数量在白垩纪的最后220万年中逐渐减少。本研究还将解决确定灭绝速度的一般问题，包括地语学问题，采样和保存偏差，以及（古）生态控制。
