It has been suggested by Paul Willis that the mekosuchine "Mekosuchus inexpectatus" was arboreal, given its small size. An arboreal lifestyle is otherwise unknown in crocodyliforms. Given that "Trilophosuchus" is similar in appearance to "M. inexpectatus", it has often been suggested that it too was arboreal. "Mekosuchus inexpectatus" has a limb bone structure that may be compatible with an arboreal lifestyle, but there is no evidence for climbing abilities in "Trilophosuchus". Because of the lack of evidence, an arboreal lifestyle is not agreed upon by other paleontologists.
