context_page_description: Kritosaurus is an incompletely known genus of hadrosaurid dinosaur. It lived about 74.5-66 million years ago, in the Late Cretaceous of North America. The name means "separated lizard", but is often mistranslated as "noble lizard" in reference to the presumed "Roman nose".
context_section_description: Kritosaurus was a hadrosaurine hadrosaurid, a flat-headed or solid-crested duckbill. Though many species and specimens have been referred to the genus in the past, most of them do not show the shared distinguishing characteristics to allow them to be considered part of the genus, or have been synonymized with other genera of hadrosaurs. The closest relative of Kritosaurus navajovius is Anasazisaurus horneri (or Kritosaurus horneri), which, together with close relatives such as Gryposaurus and Secernosaurus, form a clade called the Kritosaurini within the larger clade Saurolophinae. Location and time separate Kritosaurus and the slightly older, primarily Canadian Gryposaurus, along with some cranial details.
  The following is a cladogram based on the phylogenetic analysis conducted by Prieto-Márquez and Wagner in 2012, showing the relationships of Kritosaurus among the other Kritosaurini:
