These dinosaurs were named in the Cretaceous Reptiles chapter by Hunt and
Lucas in the 1993 SVP meeting Field Trip Book on Vertebrate Paleontology of
New Mexico.  As I recall, they are both roman-nosed hadrosaurine
hadrosaurids.  Both were previously described as Gryposaurus or
Kritosaurus, and in fact may just be additional specimens of one or both of
these genera.  The alledged differences between these two and Gryposaurus
are mainly slight differences in snout shape, which might be legitimate
differences or might be simple individual variation.

I might have the order mixed, but I believe the full names are
Anasazisaurus horneri and Naashoibitosaurus ostromi.

I don't have the full reference on me, but the chapter is something like
"Cretaceous Reptiles of New Mexico" and the volume _Vertebrate Paleontology
in New Mexico_.
