Dissertation Research: Phylogenetic Systematics of EusuchianCrocodylomorpha

小行星9423428 本项目是基于头骨和颅后骨骼的形态特征，研究现存鳄鱼和它们最近的灭绝亲属（尤苏克）之间的进化关系。使用计算机体层摄影或CT扫描将允许研究颅骨形态的详细方面，并提供额外的分析特征来源。 %%% 鳄类动物的进化关系的研究是有意义的，因为它首次包括了化石和活的分类群以及来自颅后骨骼的特征。除了建立一个crocodylians，本研究将探讨字符的进化与水生适应和鳄鱼进化的发展时间（异时性）的差异的作用。 ***

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. ***
