Here’s what happen…

Theyd kill and destroy a few things and then would get contained by the authorities

Tyrannosaurus,here is all the reasons why

1. It is the largest Apex carnivore to have ever lived on land

2. It has the strongest bite force of any animal

3. It is very robust and even if it was brought back to life,it would have to be in Africa instead of the USA since it would hunt everything in its sight,plus it would have to be with a few animals that can rival it
