ABSTRACT In this project, students will conduct fieldwork to characterize the pale environmental setting of an Upper Jurassic dinosaur site in the Bighorn Basin of Wyoming. The primary goals of the site analysis are to understand the stratigraphic setting of the site, the environments hosting fossils, and the pale ecology of the organisms preserved there. Students will work under the auspices of Hope College, in cooperation with personnel from the University of Minnesota Duluth, the Cranbrook Institute of Science, and the Cincinnati Museum of Natural History. Intellectual merit. Dinosaurs in the Morrison Formation occur in several scattered clusters of sites that represent a wide variety of depositional settings. The project site is part of an understudied cluster in the Bighorn Basin, at the northern reaches of the Morrison Formation. Although the site has yielded unusual dinosaur fossils including theropod teeth and articulated sauropod remains its paleoenvironmental setting has not been examined. Understanding the project site's pale environmental setting, dinosaur fauna, and relationship to other sites in the Bighorn Basin cluster will improve knowledge of the region and allow more equable comparisons between the Bighorn Basin and better-known regions across the Morrison Formation. These comparisons will provide a firmer basis for recognizing temporal and spatial heterogeneity in pale environments as well as pale ecological and taphonomic variation across the formation.

在这个项目中，学生将进行实地考察，以描述怀俄明州大角盆地上侏罗纪恐龙遗址的苍白环境。 遗址分析的主要目标是了解遗址的地层背景、化石所在的环境以及保存在那里的生物的苍白生态。 学生将在霍普学院的主持下工作，与明尼苏达大学杜卢斯、克兰布鲁克科学研究所和辛辛那提自然历史博物馆的工作人员合作。 智力上的优点。莫里森组中的恐龙分布在几个分散的遗址群中，代表了各种各样的沉积环境。 该项目所在地是大角盆地一个未充分研究的群的一部分，位于莫里森组的北方河段。 虽然该遗址已经发现了不寻常的恐龙化石，包括兽脚亚目恐龙的牙齿和关节型蜥脚亚目恐龙的遗骸，但其古环境尚未得到研究。 了解项目现场的苍白的环境设置，恐龙动物群，并在大角盆地集群的其他网站的关系将提高该地区的知识，并允许大角盆地和整个莫里森形成更知名的地区之间的更公平的比较。 这些比较将提供一个更坚实的基础，认识到时间和空间异质性的苍白环境，以及苍白的生态和埋藏变化的形成。
