Carnufex is a primitive crocodylomorph, a group including suchians more derived than Rauisuchidae.
It is the most basal of the group, along with an unnamed genus.
Zanno et al. (
2015) conducted a phylogenetic analysis, including taxa as basal as Mesosuchus and as derived as Protosuchus and Alligator.

Below is a simplified version of their cladogram, including only Loricata and Crocodylomorpha.
