The goal of this U.S.-Romanian research project between Rodney M. Feldman and Carrie E. Schweitzer of Kent State University and Iuliana Lazar of the University of Bucharest is to expand our knowledge of the diversity of fossil decapods during Jurassic and Cretaceous time intervals when stem groups of the order experienced major diversification events that set the stage for the appearance, then expansion, of modern decapod fauna, such as crabs, lobsters and shrimp. The team of U.S. and Romanian experts and students will jointly examine the sedimentological history and paleontology of four sites in the southern Carpathian Mountains, a region that has not been well studied due to previously limited access. Stable isotope analyses and new data derived from the fieldwork will be combined to describe the taphonomic and paleoecological history of the assemblages. Because these mountains lie at a crossroads between northern and western Europe, known to contain rich decapod faunas in the Jurassic and the Tethyan seaway to the south, the researchers hope to determine where the two major diversification events were centered. Results are expected to enrich our understanding of the taxonomy, biostratigraphy, biogeography and evolution of decapods, a globally important group of organisms. This project in paleontology fulfills the program objective of advancing scientific knowledge by enabling experts in the United States and Central Europe to combine complementary talents and share research resources in areas of strong mutual interest and competence. Broader impacts include the introduction of U.S. students to the benefits of international collaboration through fieldwork at Carpathian sites and direct involvement in the project's analysis of ancient sediments and fossil decapod radiation.

肯特州立大学罗德尼·费尔德曼（Rodney M. Feldman）和凯莉·施维策（Carrie E. 虾。 美国和罗马尼亚专家和学生团队将共同研究南部喀尔巴阡山脉四个地点的沉积学历史和古生物学，该地区由于以前有限的通道而尚未对该地区进行过很好的研究。 稳定的同位素分析和从现场工作得出的新数据将结合使用，以描述组合的taphonomic和古生态历史。 由于这些山脉位于北欧和西欧之间的十字路口，众所周知，在侏罗纪和南部的Tethyan Seaway中包含丰富的Decapod动物群，因此研究人员希望确定两个重大多元化事件的中心。 预计结果将丰富我们对分类法，生物地层学，生物地理学和Decapods的进化的理解，Decapods是全球重要的生物群体。古生物学项目实现了计划的目标，即通过使美国和中欧的专家能够结合互补才能并在浓厚的共同利益和能力领域中共享研究资源来促进科学知识。 更广泛的影响包括通过在喀尔巴阡山脉的实地调查引入美国学生对国际合作的好处，并直接参与该项目对古代沉积物和化石Decapod辐射的分析。
