Majungasaurus vs Rugops

Majungasaurus takes this.

I think you guys are forgetting that while known specimens of Rugops and Majungasaurus are about the same length, Rugops is only known from juvenile material. The adult Rugops is probably much larger than Majungasaurus. Moreover, Majungasaurus had an extremely odd skeletal design when compared to other abeliosaurids, as shown by Scott's reconstruction:



Not sure how this would effect it's fighting abilities, but Majungasaurus has got stockier legs and a more elongate body than any other abeliosaurid known. Kinda like a "Dinosaurian Dachshund" as described in All Yesterdays.
