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.
