in Marasuchus and Nundasuchus, and therefore had a variable existence in Archosauria. This reanalysis, along with the observance of many traits linking Phytosauria with pseudosuchians, concluded that it was more likely that phytosaurs were pseudosuchians than non-archosaur archosauriforms. The following cladogram is a simplified version the fourth strict reduced consensus tree of Ezcurra's third phylogenetic analyses within his study. This cladogram only shows taxa from the group Eucrocopoda. Footnotes Sources Abler, W.L. 2001. A kerf-and-drill model of tyrannosaur tooth serrations. p. 84–89. In: Mesozoic Vertebrate Life.
