In spite of their obvious potential utility, trace fossils and ichnofabric have been incorporated only rarely into stratigraphic analyses. For their potential to be fully realized, a predictive model based on all aspects of the ichnological record must be developed within a well-constrained stratigraphic horizon. The purpose of this research is to document discrete trace fossils and their distributions, record ichnofabric indices, and describe the ichnofabric from the Cincinnatian Kope-Corryville succession. The sequence and cyclo-stratigraphy of these strata have received considerable attention in the past ten years and a high resolution choronostratigraphic study is currently underway. As a result, a well constrained stratigraphic framework has emerged providing an ideal opportunity to test the utility of the ichnological record in stratigraphic analyses. These strata have an additional advantage; the Ordovician represents a critical time in the history during this time. This study will aid in our understanding of the history of the benthic community during the Ordovician radiation. Dr. Droser will also attend the Third International Ichnofabric Workshop at the University of Lopenhagen, Denmark and participate in field trips that include visits to similar age strata to the Cincinnationa Kope-Corryville succession but that represent very different environmental conditions of deposition. The interactive activities consist of five main facets: teaching one graduate-upper level undergraduate seminar in ichnology; participating in additional paleontology and departmental seminars; actively involving students, particularly undergraduates, in research; leading general department field trips; and leading field trips for middle school and high school museum volunteers at the Cincinnati Museum of Natural History.

尽管它们具有明显的潜在效用，但痕迹化石和物质结构很少被纳入地层分析中。 为了充分发挥其潜力，必须在严格约束的地层范围内开发基于地质记录各个方面的预测模型。 这项研究的目的是记录离散的痕迹化石及其分布，记录物质结构指数，并描述辛辛那提科普-科里维尔系列的物质结构。 这些地层的层序和旋回地层学在过去十年中受到了相当多的关注，目前正在进行高分辨率的年代地层学研究。 结果，一个约束良好的地层框架出现了，为测试地层分析中的地貌记录的效用提供了理想的机会。 这些地层还有一个额外的优势： 奥陶纪代表了这一时期历史上的一个关键时期。 这项研究将有助于我们了解奥陶纪辐射期间底栖群落的历史。 Droser 博士还将参加在丹麦洛本哈根大学举行的第三届国际织物研讨会，并参加实地考察，其中包括参观与辛辛那纳科普-科里维尔系列年龄相似但代表截然不同的沉积环境条件的地层。 互动活动包括五个主要方面： 教授一场研究生高水平本科生的植物学研讨会； 参加其他古生物学和部门研讨会； 积极让学生，特别是本科生参与研究；领导综合部门实地考察；并带领辛辛那提自然历史博物馆的初中和高中博物馆志愿者进行实地考察。
