Tyrannosaurus Rex, though, lives in an entirely 1 different world. A male devours 2 a Triceratops carcass.
Those powerful jaws 3 smash into the meat of the animal. Those gigantic teeth pierce down through flesh. These well-rooted teeth are there to break into the bones.
Scavenging keeps T. Rex alive. Maintaining strength is essential. His chicks are depending on him. Left alone, they're as vulnerable as a clutch of baby Sauroposeidon.
And a Quetzalcoatlus has a voracious 4 appetite. Soaring at 3,000 meters, a sense of smell is useless. This flying reptile 5 relies on its incredible eyesight
to scan for vulnerable infants on the ground.
It could make the difference between a meal and no meal. It zeroes in on a target. A meter-long baby T. Rex appears on the radar 6.
It's gonna need to have fairly good distance vision to be able to see just generally where it's going and targets on the ground.
They would have been just about the right size to be a snack for Quetzalcoatlus.
Luckily, just as this massive flying reptile approaches the nest, the male senses trouble. His ultra-sensitive olfactory 7 lobes 8 pick up the distinctive 9 scent 10 of Quetzalcoatlus.
This triggers a rush of chemicals to the brain, and an immediate 11 decision to return to the nest. But Quetzalcoatlus are fast. And it only takes a split second to launch their 180-kilo body into the sky. The other chicks might just make it for another generation.
