With this mod you'll be able to change the appearence of the Huayangosaurus to a more accurate look (in the current limits of modding)

A full list of the changes:
-Resized the head to the limits given by the rig (originally reduced it to the correct size; animal had serious animation issues)
-opened up the eye, adjusting the brow ridge to be more thin, in line with fossil evidence
-severely reduced the ridges going down to the premaxilla, giving the animal a more stegosaurian look
-adjusted the temporal area of the cranium, making the skull less rounded
-slightly thinned out the skull (any more than that gave animation issues)
-opened up the underside of the jaw and adjusted the muscolature attaching to the angular and surangular bones
-completely remade the neck, thinning out unnecessary muscles and giving it the correct posture (no more elephantiasis on newly born Huayangosauruses ;P)
-reworked the spine to give it proper posture
-remade the osteoderms to the shapes they should have, reflecting paleontological data
-enlarged osteoderms to take into account keratine growth over the bony interior, giving them a way more sharper look
-same as above for the shoulder osteoderms
-gave the animal a coracoid bone, gastralia, ischium and pubis
-remade the tail in length, thickness and posture to reflect fossil evidence
-pointed the tip of the tail downward to take into account thagomizer weight
-augmented the thagomizer's length and sharpness to reflect keratin growth over the bony interior.
