With this mod you'll change the Maiasaura to look more accurate to the fossil material we have on the species.

A full list of the changes:
-Remodeled the brow horns to be closer to the actual fossils, removing the unibrow in favor of more accurate hornlets
-made the temporal area of the skull rounder and less flat, taking in consideration both skull shape and muscolature attached to it
-remodeled the beak to fit the shape seen in fossil evidence, taking into consideration keratin overgrowth
-made the jaw deeper and more muscolar
-moved the masseter frontally
-made the neck more muscolar, tweaking various muscles (m. Transversospinalis capitis, Complexus, m. Transversospinalis Cervicis, m. Longissimus Capitis Superficialis)
-tweaked neck posture and curvature
-gave the animal proper scapulae and a gastralia
-moved the "hump" frontally
-smoothed out the Ischium and Pubis to be less evident
-made the tail slightly thinner in the final section
