 To eviscerate prey, Deinonychus uses both its hands and feet. These were animal that had weapons everywhere you go.

 

It’s ridiculous minor weaponry for animal like that size. It’s clear its name of all for every reason to be able to dish a lot of damage for its size.

 

For a young Sauroposeidon, even one the size is polar bear, Deinonychus is a fierce opponent. And when there is a pack of these savage killers, a lone Sauroposeidon has little hope of surviving their own slot. But they do survive, and grow up to one day become almost indestructible. For Tyrannosaurus Rex, the most advanced carnivore that has ever lived, the odds are even harder.

 

The T-Rex chicks wait near the nest. The female is far away on a hunt, trying to replenish her strength. The male stays behind to guard the roost.

 

There’s always this idyllic picture of this female Tyrannosaurus is guarding her clutch of eggs.

 

May have been the male as far as we know. I mean, the female could have said, "Buddy, you caused the problem. You take care of them." But the male needs to eat, too.

 

A warm-blooded carnivore can’t last for long without a meal. A scent travels on the breeze, an aroma his brain instantly recognizes—a dead and rotting Triceratops.

 

It’s a tempting proposition for the T-Rex, not least because it can’t fight back,

 

There’s this debate whether T-Rex was scavenger or predator. The answer of that is it was both. Any large animals need to be able to find food on a regular basis. These guys are warm-blood. They need to eat frequently.
