Dissertation Research: Phylogenetic Systematics of EusuchianCrocodylomorpha

9423428罗这个项目是基于头骨和颅后骨骼的形态特征，研究现存的鳄鱼和它们已灭绝的近亲(真鳄鱼)之间的进化关系。计算机断层扫描或CT扫描的使用将允许研究颅骨形态的详细方面，并提供另一种用于分析的特征来源。鳄鱼进化关系的研究具有重要意义，因为首次包括了化石和活的类群以及来自后颅骨的特征。除了建立鳄鱼的系统发育，这项研究还将调查与水生适应有关的特征进化，以及发育时序差异(异时性)在鳄鱼进化中的作用。***

9423428 Rowe This project is a study of the evolutionary relationships among living crocodylians and their closest extinct relatives (eusuchians) based on morphologic characters from the skull and postcranial skeleton. The use of computed tomographic or CT scanning will permit study of detailed aspects of cranial morphology and provide an additional source of characters for analysis. %%% The study of crocodylian evolutionary relationships is significant in terms of including for the first time both fossil and living taxa and characters from the postcranial skeleton. Beyond establishing a phylogeny for crocodylians, this study will investigate character evolution in relation to aquatic adaptation and the role of differences in developmental timing (heterochrony) in crocodylian evolution. ***
