Anasazisaurus

Name: Anasazisaurus ‭(‬Anasazi lizard‭)‬.
Phonetic: An-ah-sah-ze-sore-us.
Named By: Adrian P.‭ ‬Hunt‭ & ‬Spencer G.‭ ‬Lucas‭ ‬-‭ ‬1993.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Ornithischia,‭ ‬Ornithopoda,‭ ‬Hadrosauridae,‭ ‬Saurolophinae.
Species: A.‭ ‬horneri‭ (‬type‭)‬.
Diet: Herbivore.
Size: Skull about‭ ‬90‭ ‬centimetres long.‭ ‬Total size uncertain.
Known locations: USA,‭ ‬New Mexico‭ ‬-‭ ‬Kirtland Formation.
Time period: Campanian of the Cretaceous.
Fossil representation: Skull.

       Anasazisaurus is currently only known from a single skull,‭ ‬but one that has a flange of bone rising from the top of its snout.‭ ‬Because this crest is solid,‭ ‬Anasazisaurus has been identified as a saurolophine hadrosaurid.‭ ‬The skull of Anasazisaurus was once attributed to the genus Kritosaurus,‭ ‬but because the skull contains several unique features it was used to create its own genus.‭ ‬While most consider this to be correct however,‭ ‬some have questioned the move suggesting that the skull should be re-classified as belonging to Kritosaurus.
       Anasazisaurus lived alongside other hadrosaurs such as Parasaurolophus as well as ceratopsians like Pentaceratops and Titanoceratops.‭ ‬Predatory threats likely came from tyrannosaurs like Bistahieversor.
