Hadrosauridae Dinosauria Ornithischia Cerapoda Ornithopoda Iguanodontia Duck-billed dinosaurs with tooth batteries.

Kritosaurus is an incompletely known genus of hadrosaurid (duck-billed) dinosaur. It lived about 74.5-66 million years ago, in the Late Cretaceous of North America. The name means “separated lizard” (referring to the arrangement of the cheek bones in an incomplete type skull), but is often mistranslated as “noble lizard” in reference to the presumed “Roman nose” (in the original specimen, the nasal region was fragmented and disarticulated, and was originally restored flat).

What we know

  • Named by Brown, 1910.
  • Body length estimated at about 9 m.
  • Fossils found in North America and India.
