In this project, Dr. Dagosto will study approximately 200 postcranial skeletal remains of specimens of the genus Hemiacodon. This is a form of early primate which inhabited both Europe and North America during the Eocene period. Dr. Dagosto will visit museums in both the United States and Europe which contain these specimens. She will describe and measure them to produce a comprehensive assessment of the limb skeleton in order to: 1. assess variation among species; 2. reconstruct locomotor and postural behavior; 3. test competing ideas on the taxonomic place of these groups within the primate order. While research has been conducted on Hemiacodon cranial remains, postcranial materials remain undescribed. Relatively little is known about the early stages of the development of the primates and the position of the group to which Hemiacodon belongs has been much debated. This research should help to resolve this issue and provide new insight into the emergence of the human lineage.

在这个项目中，Dagosto博士将研究大约200个半齿龙属标本的颅后骨骼遗骸。这是一种早期灵长类动物，在始新世时期居住在欧洲和北美。达格斯托博士将参观美国和欧洲藏有这些标本的博物馆。她将描述和测量它们，以产生肢体骨骼的综合评估，以便：1。评估物种间的变异；2. 重建运动和姿势行为；3. 测试关于这些群体在灵长类目中的分类学位置的相互竞争的观点。虽然对半齿鲨颅骨遗骸进行了研究，但颅后材料仍未被描述。相对而言，我们对灵长类动物发展的早期阶段所知甚少，而半齿龙所属群体的地位也一直存在争议。这项研究应该有助于解决这个问题，并为人类血统的出现提供新的见解。
