Private Notes
A very long time ago, some tiny creature discovered how much more efficient it is to convert its neighbour into food than to convert sunlight into food. By the time of the dinosaurs, the ever-escalating arms race of predator and prey had brought about some of the most remarkable deadly killing machines that the Earth would ever see.
Palaeontologists are discovering and re-creating the mechanisms by which the dinosaurs gradually adapted to flight; and they're finding that the Pterosaurs were once as diverse as modern birds.
Some 60 Million years ago, a strange and fierce bear like creature tested the waters of an ancient ocean, it's descendants - Whales and Dolphins.
In isolated pockets of the Cretaceous and Jurassic worlds, the evolutionary experiment of the dinosaurs sometimes seems to have run amok. The result: extremes of size, shape, and lifestyle that seem to defy the notion of survival of the fittest.
Human paleontology reaches back to find the origins of human kind. PaleoWorld explores how we survived, the gaps in our knowledge, and the twists, turns, and dead ends in our evolutionary pathway.
While the dinosaurs ruled the earth, super giant squid, ancient sharks and 20 foot long crocodiles held sway in the seas.
When the curtain rang down on the dinosaurs, the mammals took centre stage. But mammals actually had their start long before the first dinosaurs - and they were as bizarre and mysterious as the dinosaurs themselves.
With astonishing rapidity, tiny mammals stepped into the void left by the extinction of the dinosaurs. In the blink of an eye, evolution-wise, giant predators once again strode the earth: saber-toothed lions and tigers, dire wolves, and even saber-toothed marsupials.
Fossils attest to dinosaur mating rituals.
This episode explores mistakes of paleontologists about prehistory.
From Godzilla, the fire-breathing film star of the 50s, to Sue, the latest and greatest Rex discovery of them all, these dinos were the perfect predators--or were they? The debate is ongoing, even as we learn more intimate details about this creature.
From the smallest notch on a giant fossil, paleontologists can infer the most amazing details of the long-missing parts of a dinosaur--nervous systems, vital organs, giant musculature, and even how well they can hear and see. High-tech medical equipment is now letting us see inside the head of a T. Rex and into the unhatched embryos of dinosaur eggs.
Dinosaurs flourished on every continent 65 million years ago. Then they vanished. Many incompatible theories have been developed to explain the dinosaurs' extinction.
