 Tyrannosaurus Rex when we think about it, we tend to think of the big adult because that’s the skeletons that we see, but we know that they didn’t hatch that way. 


 
Once those eggs hatched, we’ve got an animal that’s maybe, you know, three feet long, maybe weighs about five to eight pounds. Comparing that to the adults, which might weigh as much as seven tons and be 40 feet in length, you know, how is this animal gonna be careful to not step on these little beasts and let alone try to protect them and try to make sure that they’re going to be cared for.
 
There is nothing fearsome without them. Sure maybe someday they’ll become a fearsome animal but at that time, they are just a meatball on legs.
 
Wherever this T-Rex looks, he stares danger in the face. 
 
There were crocodiles, medium, large, to gigantic that could plop down, swallow baby T-rexes like maraschino cherries.
 
Clearly, a young T-Rex is very susceptible 1 to be eaten by just about everybody else who’s around, who likes to eat meat. 
 
And danger isn’t limited to the ground. Sometimes it dives out of the sky. Quetzalcoatlus,a one hundred and eighty kilogram flying carnivorous reptile 2, circles, waiting for the right moment to strike.
 
Quetzalcoatlus would make all the animals in the Late Cretaceous scare. 
 
With a 42-foot wing span, they could shut out the sun.
 
One tool that makes this flying reptile so effective is a highly advanced eyeball. Its eyes are built like a hawk’s and are able to see with four times the clarity of a human eye and with a retina over ten centimeters wide containing over a billion light receptors. This is a reptile that sees the world in high definition.
