With this mod you'll be able to change the in-game Allosaurus to a more accurate one; from a redone head and crests, to non pronated hands.

A full list of the changes:
-Reshaped the premaxilla to a more boxy look, closer to fossil evidence
-created a ridge from the nasal bone, as observed in fossils
-created lacrimal brows
-removed ridges above, around and behind the eyes
-moved the teeth to the accurate position
-created a lip to partially cover the teeth
-adjusted jaw thickness
-adjusted the neck to have a more accurate curvature
-gave the animal an extensive and thick dewlap
-gave the animal a coracoid bone
-adjusted the underbelly to reflect the gastralia properly
-made the animal a bit bulkier to take into account body muscolature (rectus abdominus, serratus ventralis, m. longissimus dorsi)
-evidenced scapulae
-gave the animal unpronated hands
-adjusted the fingers to be less skeletal
-adjusted the claws of the manus to reflect fossil evidence
-slightly reduced manus size
-reduced the ischium and pubis to take into account the muscolature above the bones themselves (external abdominal obliques)
-adjusted the tail in thickness, length and posture

There are two versions of this mod:
-the Scuteless version is the Allosaurus in its most accurate to (known) science representation
-the Scuted one is the same model as the other but retain the crocodile scutes on the back
