Dissertation Research: Morphometric and Microwear Analysis of Fossil Primates (Adapidae: Notharctinae): The Relationship Between Tooth Shape and Diet in an Evoling Clad

古生物学家一直希望通过对牙齿化石的研究揭示现存和灭绝脊椎动物的饮食、生态适应以及进化关系。这项研究，利用扫描电镜臼齿微磨损分析来推断饮食，以及基于地标和轮廓的牙齿形态计量学，将揭示在一个重要的已灭绝灵长类动物群体中，牙齿的形状和使用是如何在相当长的时间间隔内发生变化的。此外，来自怀俄明州始新世早期序列的古土壤数据表明，那里的变化可能与牙齿微磨损和形态变化有关，这将是一个突破。该项目将有助于研究这些灵长类动物进化变化的速度和模式。它还将在一个优秀的项目中培养一名非常有能力的年轻研究员。* * * P人类学\ jfried \ \ 9316019。腹肌​!！ ！ D (Times New Roman Symbol & Arial S " h e e = Jonathan Friedlaender

ABSTRACT P.I. Kenneth Rose/Maureen O'Leary SBR-9316019 Paleontologists have always hoped the study of fossil teeth would reveal the diet, ecological adaptations, as well as the evolutionary relationships, of living and extinct vertebrates. This study, using SEM molar microwear analysis to infer diet, and also landmark-based and outline-based morphometrics of the teeth, will reveal how dental form and use changed over a substantial time interval in an important extinct primate group. Also, paleosol data from this early Eocene sequence in Wyoming suggests that variation there can be tied to the dental microwear and morphological changes, which would be a break-through. The project will contribute to the study of the tempo and mode of evolutionary change in these primates. It will also train a very competent young researcher in an excellent program. *** P\anthro\jfried\9316019.abs ! ! !
