Ultimat fight of predator vs his prey

A single ceratosaurus is looking for his next food. But the only thing that he has is a full grown stegosaurus. He needs to be careful. A movement of the stegosaurus tail, and ceratosaurus is dead, if the fight doesn´t kill him first.
PALEONTHOLOGIST: He is decided to kill that animal.
Ceratosaurus bites the leg of stegosaurus and break that bone. Ceratosaurus know that other bite like that one and that is all, GAME OVER. Stegosaurus hit the ceratosaurus in the face, but doesn´t cause so damege. Ceratosaurus take other bite and stegosaurus slows to the ground.
PALEONTHOLOGIST: Ceratosaurus has won the battle and starts to eat his prey. But this fight had not end.
Stegosaurus with all the strenge he has swings his tail and hit on the ceartosurus face, braking all the skull. But that won´t help. Stgosaurus is going to die slowly. Both animals are going to die very painfully.
