A nearly complete skull of Eutretauranosuchus delfsi was uncovered at the upper Jurassic Dry Mesa Dinosaur Quarry in the Brushy Basin Member of the Morrison Formation in western Colorado. It permits an expanded description of the taxon. Like the holotype, from Canyon City, Colorado, the Dry Mesa specimen probably represents a subadult, based on faint parallel lincations in the frontal, incomplete ossification in the otic region, incomplete sculpturing of the dermal bone, and an incompletely fused occipital condyle. The Dry Mesa specimen is compared with the type specimen, crocodyliformes Amphicotylus, photographs of the type specimen, and other related crocodyliformes described in the literature. A phylogenetic analysis lends support to a close relationship between Eutretauranosuchus, Calsoyasuchus, and Sunosuchus.
