Its reputation for violence and terror is unmatched, but an infant T-Rex comes into the world better protected than most. If you say Tyrannosaurus Rex, I think of gentleness. I think of superb motherhood and a struggle to raise ones chicks. The dread

I think its a very beautiful idea that you have this little egg thats surprisingly small and out of it comes a baby sauroposeidon thats about the size of a rabbit and in two or three decades, its gonna be a 50-ton adult. But why does this huge animal

Tyrannosaurus Rex when we think about it, we tend to think of the big adult because thats the skeletons that we see, but we know that they didnt hatch that way. Once those eggs hatched, weve got an animal thats maybe, you know, three feet long, maybe

There probably werent many animals of Cretaceous that would dare to try to grab a baby Tyrannosaurus Rex. Quetzalcoatlus could probably manage it. If you see a stork on the Nile today eating a baby crocodile, you can imagine in your mind Quetzalcoatl

When you start off coming out of the egg and youre less than, say, 2 feet long and you are in a world full of predators that are loving to crunch on you, then you need to get big fairly quickly. The future seems bleak for this dinosaur. With its life

Male lions defend their cubs against rivals who see their offspring as future competition for food and mates. So its likely that an intelligent predator like T-Rex would do the same. Compared to prehistoric plant eaters, its cerebrum, the part of the

T-Rex is impressive and it's powerful, but compare to Ankylosaurus, it is relatively lightly built. Protective plates made of bone and cartilage covered this lumbering creature from head to tail. Light, but extremely strong, the hide of Ankylosaurus

And there is something else unusual about a T-Rexs nose. The nostrils are a huge 25 centimeters apart, which means T-Rex can smell in stereo. It can triangulate an odor and pinpoint its exact source. T-Rex could walk into a crowded auditorium and in

One could imagine that the conflict between Tyrannosaurs and Triceratops may have been one of the greatest combats that nature has ever had. And this well-protected herbivore is everywhere. In fact in the Late Cretaceous, Triceratops outnumbered Tyra

Sauroposeidon probably had a brain about the size of a kittens, because it was not, unfortunately, a very smart animal. It didnt have to be. It was a food-processing plant. Sauroposeidons five senses are little more than a life-support system for the
