tyrannosaurus
Facts
Its teeth got up to 8 inches long and the head 4 feet long and longer for both teeth and skull.
It had a strong flexible neck to change its attack angle at any time.
It had a large brain for smell and sight which is good predator coordination.
It had puny arms so it had to be careful at if it fell in its head and broke its skull. The T-Rex puny arms couldn't catch him if he fell.
Its jaw muscles were so strong that it could tear through a thick leg bone. Its razor teeth helped.
The tail was a good balancer for the T-Rex's weight.
