Why do carnotaurus have small arms?

As fearsome as Carnotaurus looked, though, it’s hard not chuckle at the dinosaur’s arms—the hand and lower part of the forelimb were so reduced in size that some paleontologists have viewed them as vestigial structures that have almost entirely lost their ability to function in acquiring prey.

What are the fastest dinosaurs?
