In Williamson T.E. (2000) Review of Hadrosauridae (Dinosauria,Ornithischia) from the San Juan Basin, New Mexico. in Lucas S.G. and Heckert A.B. (eds) Dinosaurs of New Mexico. pp:191-213. New Mexico Museum of Natural History and Science Bulletin n.17. Williamson argued that Anasazisaurus Naashoibitosaurus and are synonym of Kritosaurus navajovius?.
BYU 12950 [holotype]: partial skull
(\\\\\\\"Anasazi lizard\\\\\\\" Named after the Anasazi, an ancient people of the American southwest) For a hook-nosed skull attributed to the species Kritosaurus navajovius? by Jack Horner in 1992. Hunt and Lucas considered Kritosaurus a nomen dubium, based on undiagnostic type material, and proposed the new name for a taxon distinguished by \\\\\\\"possessing a short, posteriorly folded nasal crest that is above the level of the frontals, but does not extend posterior to the anterior end of the frontals.\\\\\\\" Anasazisaurus and Naashoibitosaurus representing possible variants of Kritosaurus navajovius?.
Horner, J.R., Weishampel, D.B. & Forster, C. (2004) Hadrosauridae in The Dinosauria eds. Weishampel, Dodson and Osmolska. pp 460. Little can be said about the relationships of Kritosaurus navajovius? and Anasazisaurus horneri, both from the Late Cretaceous of the southwestern United States. They are diagnostic at the species level, but are currently too incompletely known to allow placement within the context of euhadrosaurian phylogeny.
