Last week I got to spend a day out with paleontologist Grant Zazula and his two assistants. We spent about 10 hours walking over a creek bed in a gold mine that has yielded extraordinary fossil remains. This is a fully working gold mine, and the owner lets paleontologists explore freely. Grant promised a day filled with finding pre-historic bones, and he was right!
Early on in the morning I found a pre-historic bison horn (about 45 cm long) that Grant estimates is 25-30,000 years old! Later ...

When dinosaur fossils survive the elements for millions of years, it’s outrageous to know that looters and vandals can destroy them in the span of a couple of hours.
Last week, a Hadrosaur dinosaur skeleton was smashed overnight in Peace Country, Alberta, the area’s fourth fossil crime in the past six weeks. The Hadrosaur, which was found on June 15 and partially prepared for display in the new Philip J. Currie Dinosaur Museum in northern Alberta, was discovered shattered on July 5, robbing ...

It all started with a log. Joel Barker, an earth scientist from Ohio State University, was researching carbon dioxide emissions on Ellesmere Island, Nunavut, when he was told about an odd log sticking out of the snow. Since trees only grow sparsely and to a few feet high on the tundra, it was definitely out of place.
"I knew that was a rare thing and I was interested in seeing it," Barker tells CG, "I knew there was a possibility of forests up there in the past. When they told me they found ...

Climate Futures. October 2010.
Our climate futures issue in October struck a chord with many Canadians. Some thought we didn't do enough to warn about the dangers of a warming world and urge action. Others thought that we did too much and wondered why we would cover the topic at all.
Below we've collected together a mixed-bag of the mail we received to show the spectrum of opinions that arrived at our door.
We would like to hear more and welcome you to add your voice. What do you think ...

Did you know that sea otters float on their backs in groups called "rafts," sometimes holding paws with fellow otters to avoid drifting apart?
Embracing the notion of power in numbers, this is how they protect themselves against predators such as bald eagles and sharks. Peregrine falcons, for their part, are consummate creatures of habit, regularly returning to the same nesting sites. Falcon pairs have apparently used one site in England for more than 760 years!
This is but a glimpse of the ...
