In Depth

       Equijubus seems to have been a primitive hadrosauroid from the early Cretaceous of China,‭ ‬though some have considered the genus to be more simply an iguanodont.‭ ‬Despite this,‭ ‬the skull of Equijubus lacks a palpebral bone,‭ ‬meaning that the eye did not have a bony projection jutting above it.
