T. rex's tail muscles made it one of the fastest dinosaurs of its time. They thought it was just to balance the weight of its big head. Earlier researchers thought it was a scavenger only able to survive by feeding on animals killed by other predators.They discovered the muscles in its body discovering how it was able to move fast.

I think this is cool because it was always thought as slow dinosaur. But actually it was one of the fastest. also because it was always said to be a scavenger because it was thought as slow and not able to kill prey. i always thought it was the way the older scientists said it was.
