The phylogeny of basal metasuchians has experienced many revisions in recent years.[1] The phylogeny of notosuchians has been particularly revised, with the construction of Sebecia by Larsson and Sues (2007) to include peirosaurids in the clade.[3] Previously, peirosaurids were placed outside Notosuchia. Larsson and Sues (2007) also suggested that Sebecosuchia (containing the families Baurusuchidae and Sebecidae) was polyphyletic, as Baurusuchus was placed outside Sebecia, which itself was placed outside Notosuchia. However, more recent phylogenetic studies have placed Baurusuchus within Notosuchia once again, although it is still not considered to be a sebecosuchian.[1]
In 2012, a phylogenetic study was done to produce supertrees of Crocodyliformes, including 184 species.[4] The most parsimonious trees were highly resolved, meaning the phylogenetic relationships found in the analysis were highly likely. As such, below is the consensus tree from the study, focusing on the Metasuchian branch of the tree.
