Dinosaurs: A Blast From The Past

Dinosaurs are some of the greatest creatures that have ever roamed the surface of this Earth. Some of them standing at heights of over 80 feet, were large species that were diverse in nature. Some flew across the sky with their wings so large that it made a sunny day seem cold and dark. The Quetzalcoatlus is the largest avian dinosaur and stood at a height equal to a giraffe. When in the air, their wingspan was around 37 feet wide!

Other fierce and more common dinosaurs included the Tyrannosaurus rex and Brachiosaurus altithorax. These two creatures were complete opposites of each other. One was a gentle giant while the other was a fast-moving predator. The Brachiosaurus is best known for its long neck, similar to a giraffe. These gentle giants were herbivores that would feed on plants in trees high in the sky. One of the funniest things about them is the structure of their body. They are in a family known for having small skulls. Their skull was around the size of a horse head yet, their body was the size of a building.

Fortunate for human survival, most of these beasts that roamed the Earth became extinct due to a cataclysmic event. The stories are true, an asteroid hit the Earth, somewhere around Mexico, and caused immediate death to millions of species nearby. This event even created an ash cloud so large that you would not see the light of day for weeks. Not all creatures died, however. Species such as the shark and alligator still live with us today and are some of the most feared creatures alive. Who knows what can still be alive from the pre-historic era?
