Personally, I always thought that carnotaurus would ambush smaller dinosaurs and ram them to the ground, causing bones to break. After all, the horns looks to small to be used for mating competitions and I heard that the jaws were too weak to be used for biting on to moving animals.
Very nicely done. the only inaccuracy i noticed is the tail. it's tail is not thick enough. a recent study shows Carnotaurus had a very thick, stiff tail thanks to the massive caudofemoralis muscle that attached to the caudal vertebrae. this huge muscle also helped Carnotaurus run surprisingly fast: in fact, its estimated top speed is around 31 mph. it was the cheetah of its world; a speed demon that could run down prey in a straight chase, but could not turn quickly.
From what I hear. The skin impressions were scaly. So do you think that Carnotaurus would've been all scaly then and had no feather. If that's so. Then that would mean all Abelisaurid's wouldn't have any. (Possibly would hav feathers when they're hatchlings, but would lose them all when they become an adult.)
