Still extinct, I'm afraid.

Anasazisaurus

This is a gryposaur from the Late Cretaceous of New Mexico, based on a skull 
formerly referred to Kritosaurus.  The three North American gryposaur genera 
(Gryposaurus, Anasazisaurus, Naashoibitosaurus) can be distinguished from 
each other by the conformation of the nasal arch, and certain other details 
of the skull.  In Gryposaurus and Naashoibitosaurus, the accentuated nasal 
arch ends terminates in front of the orbits.  In Anasazisaurus, the nasal 
arch extends posterodorsally all the way to above the orbits (Hunt and 
Lucas, 1993).  In this genus, the back of this nasal crest folds under 
itself, creating a small cleft between the crest and the skull roof.
