The PI will coordinate field work at the Pipe Creek Sinkhole, a recently discovered site in Grant County, Indiana, which preserves unconsolidated sediments containing a diverse late Tertiary assemblage of animals and plants. The study will be a collaborative effort between Indiana-Purdue University, Fort Wayne and the Indiana State Museum (the repository for specimens). Field work will comprise on-site wet-sieving and concentration of sediments (some sediment samples will be bagged for later sieving in the lab). Sieve concentrate will then be picked for small fossils in the lab. The PI will create a database in which each identifiable specimen will be associated with records about the sample and size fraction of sediment from which it came. This will eventually be used to analyze the paleoecology of the site. In addition, the PI will set up a lab for preparing thin sections of lower vertebrate bones from the assemblage for osteohistological/skeletochronological analysis relevant to reconstructing the late Tertiary paleoclimate in the region of the Pipe Creek Sinkhole.

PI将协调在管道溪Sinkhole的实地工作，这是印第安纳州格兰特县最近发现的一个地点，该地点保存着包含各种晚第三纪动植物组合的松散沉积物。这项研究将是印第安纳-普渡大学、韦恩堡和印第安纳州立博物馆(标本储存库)的合作成果。现场工作将包括现场湿筛和沉积物浓缩(一些沉积物样本将被装袋，以便稍后在实验室进行筛分)。然后，将在实验室中挑选筛分浓缩物用于小型化石。PI将创建一个数据库，其中每个可识别的样本将与有关其所来自的沉积物的样本和粒度比例的记录相关联。这最终将被用来分析该遗址的古生态。此外，PI将建立一个实验室，从该组合中制备较低端脊椎动物骨骼的薄片，用于骨组织学/骨骼年代学分析，与重建管道溪Sinkhole地区晚第三纪古气候有关。
