This is because the skull has been challenged as
representing a growth stage of Kritosaurus,
though other studies have
shown that it is different enough to be regarded as its own genus.
Currently however, Naashoibitosaurus is only

reliant upon future fossil discoveries and studies.
With a reconstructed skull length of eighty-three centimetres, Naashoibitosaurus would be expected to be a moderately large hadrosaur.
