Eutreptornis ("changing bird"[1])is a genus of extinct possible cariamiforme bird from the Late Eocene of Utah. It is traditionally considered to be a bathornithid,[2][3] though a combination of the relative incompleteness of the material alongside some differences from other bathornithids have raised some suspicions about this affiliation.[4][5]
