In Depth

       At times the skull of Naashoibitosaurus has been attributed to Kritosaurus,‭ ‬while the post cranial skeleton attributed to Edmontosaurus.‭ ‬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 known from a small number of fossils,‭ ‬and further clarification about the genus is 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.
