 A comprehensive study of known Kritosaurus material published by Albert Prieto @-@ Márquez in 2013 upheld the status of Naashoibitosaurus as a distinct genus , but found that the type specimens of Kritosaurus and Anasazisaurus were indistinguishable when comparing overlapping elements ( i.e. only those bones preserved in both specimens ) . Prieto @-@ Márquez therefore regarded Anasazisaurus as a synonym of Kritosaurus , but retained it as the distinct species K. horneri .
