These reptiles lived on our planet during the Triassic and Jurassic periods of earth’s history, from about 243 to 231 million years ago. Dinosaurs became extinct a long time ago and one explanation is that the earth became much cooler, during the ice age. Another explanation is that the earth was hit by a massive asteroid.
There were a huge a variety of these ‘terrible lizards’. Some were herbivorous or plant eaters, like the diplodocus. The diplodocus was the longest dinosaur with a very long neck and tail. It’s powerful tail could whip around and fight any creature that dared to come near! Others were carnivorous or meat eaters like the tyrannosaurus, which walked on two legs and could run very fast. Unlike the tyrannosaurus, the Pterodactyl was an avian dinosaur had wings and flew. Avian dinosaurs may have been the ancestors of birds.
The diplodocus and tyrannosaurus were huge, but the heaviest known dinosaur was the titanosaur, which weighed about 69 tons, more than 4 semi-trucks put together! Not all dinosaurs were massive. The epidexipteryx was only 25 cm long, about the size of a small puppy!
Have fun learning about dinosaurs and making this project!
Inuit built Inuksuit (plural of inukshuk), piles of rock, to act “act like humans” in the arctic.
An inukshuk could help an Inuit hunter in many ways. Like humans they communicated important messages – where to find good hunting grounds for walrus, seal or whales, or point to a good landing site for a kayak. Sometimes they showed the way home, or warned of danger, such as deep snow or strong undercurrents.
The shape and size depended on the kind of rock, and how they were piled on top of each other. These were sometimes huge boulders and the inukshuk was enormous and could be seen from many miles away.
“This is the violet hour, the hour of hush and wonder, when the affections glow and valor is reborn, when the shadows deepen along the edge of the forest and we believe that, if we watch carefully, at any moment we may see the unicorn.” – Bernard DeVoto
Let your imagination run wild with this fantasy animal. It could be a white horse or some other creature roaming around the Squamish woodlands! We have been obsessed with unicorns for centuries – you can find a unicorn on the coat of arms of Nova Scotia and Queen Elizabeth!
