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，但痕量化石和鱼类却很少纳入地层分析。 为了使它们的潜力充分实现，必须在构成良好的地层范围内开发基于流氓记录的各个方面的预测模型。 这项研究的目的是记录离散的痕量化石及其分布，记录鱼类的指数，并描述辛辛那提科普 - 科里维尔继承的疫苗。 在过去的十年中，这些地层的序列和环地层学受到了很大的关注，目前正在进行一项高分辨率的脉络膜地层学研究。 结果，出现了一个良好的限制地层框架，为在地层分析中测试了基因学记录的实用性提供了理想的机会。 这些地层有一个额外的优势； 奥陶纪代表了这段时间里历史上的关键时刻。 这项研究将有助于我们在奥陶纪辐射期间对底栖界的历史的理解。 Droser博士还将参加丹麦Lopenhagen大学的第三次国际ICHNOFRIC研讨会，并参加现场旅行，其中包括访问与Cincinnationa Kope-Corryville继任的类似年龄阶层的访问，但代表着截然不同的沉积环境条件。 互动活动由五个主要方面组成：教授一个研究生级的本科生课程研讨会； 参加其他古生物学和部门研讨会； 积极参与学生，特别是本科生的研究；领先的总部门实地考察；以及辛辛那提自然历史博物馆的中学和高中博物馆志愿者的领先实地考察。
