Burgess Shale

 

The Burgess Shale is located in the Canadian Rockies.  Location where researches discovered a number of perfectly preserved Cambrian Fossils. Scientists believe these organisms were buried in an avalanche that produced an airtight pocket that prevented decay of their soft tissues. The area was once a massive reef within the Pacific Ocean. Over the ages the fossils were pushed to the surface by Tectonic Movement.The reason the site is so important is because the Cambrian fossils found here challenge Darwin's theory of evolution. Located within the rocks were fossil evidence of all the basic body plans of animals exist today. No evidence of ancestors evolving into these species exists within the pre-Cambrian fossil record. This suggests that these organisms appeared instantly. Scientists are calling this event the "Cambrian Explosion" or the Cambrian Big Bang. 

Tsunami



The term Tsunami comes from the combination of the Japanese words tsu-"harbor" and nami-"wave."
A Tsunami is a series of large violent waves caused by the displacement of a large volume of water following a large tetonic event such as an earthquake, like the one that Japan; or a volcanic eruption. They usually occur in the worlds oceans, but they have been known to also occur in large lakes. Tsunami's were first documented by the Greek historian Thucydides when he referred to it as "submarine earthquakes."
