鳄形目化石遍布世界各地，是中、新生代脊椎动物中记录最完整的一种。为该组提出的关系的多个系统发育假说允许有争议的结果有足够的空间，部分原因是小的重叠类群和不一致的同源性声明之间的研究。我们提出了两个超树的鳄鱼形目，根据不同的协议源树选择，总结成一个“合成共识”的组的系统发育数据。最简约的树，包含184个终端类群的共识，有一个非常好的解决分支结构，这可能会作为一个框架，进一步的宏观进化研究。此外，IterPCR脚本首次用于超树环境中，以构建简化的共识树，修剪不稳定的分类群。
With fossils found worldwide, Crocodyliformes stands as one of the best documented vertebrates over the Mesozoic and Cenozoic. The multiple phylogenetic hypotheses of relationship proposed for the group allow plenty of space for contentious results, partially due to the small overlapping of taxa and disagreeing homology statements among studies. We present two supertrees of Crocodyliformes, based on different protocols of source tree selection, summarising phylogenetic data for the group into a 'synthetic consensus'. The consensus of the most parsimonious trees, containing 184 terminal taxa, has a remarkably well-resolved branching structure, which may serve as a framework for further macroevolutionary studies. In addition, the IterPCR script was for the first time used in the supertree context to build a reduced consensus tree with the pruning of unstable taxa.
