They are perhaps the most fascinating dead creatures on Earth. Rulers of the Earth for over 150 million years, the dinosaurs are one of the most successful terrestrial vertebrates ever. exn.ca delves into the myths, the latest discoveries and the biggest unsolved mystery of all time - what killed the dinosaurs?

Continuing the quest for the biggest dinosaur ever
(Jan. 24, 2001) In a humid forest, 170 million years ago, the ground shook like no time before. It wasn't an earthquake or volcanic eruption. It was a subtler, more constant tremor - the footsteps of four-legged dinosaurs known as sauropods. These plant-eaters were the largest animals ever to walk the Earth. With long necks that dwarfed those of modern-day giraffes and huge legs, bigger than any elephant, these creatures are the ultimate example of what makes dinosaurs so captivating. "It's amazing just how big these creatures could get," says Phil Currie, curator of dinosaurs and co-founder of the Royal Tyrrell Museum of Palaeontology in Drumheller, Alberta. Some scientists think the largest sauropods are already on display. But Currie says discoveries to-date are just the tip of the iceberg. "Everytime you think you've pushed the boundaries of what nature can do, nature surprises you and you get something bigger."

It's an archaeopteryx's life
(Jan. 19, 2001) Nearly 150 million years ago, a sparsely feathered creature called archaeopteryx roamed the forests of Pangaea in search of prey. Today, the evolution of the tiny carnivore is widely seen as a key element in the link between dinosaurs and birds. But until recently, scientists had few clues as to how archaeopteryx actually lived. Now, researchers at Oxford University say they have a much better picture of how archaeopteryx evolved, how it managed to eke out an existence and how it really used its wings.

The real 'winners' of the dinosaur age
(Sep. 21, 2000) They are perhaps the tiniest mammals that roamed the Earth. Forever in the shadows of the enormous dinosaurs that have tended to hog the media limelight, the mammals that lived through the dinosaur extinction 65 million years ago may have met their biggest promoter in Jaelyn Eberle. She is one of a handful of scientists in the world who study mammals that lived during the time of the very last dinosaurs.

"I like happy endings," says Eberle, a paleobiologist at the Canadian Museum of Nature. "And let's face it, the dinosaurs didn't have one. They got wiped out whereas the mammals survived. They're the real winners."
