Snow Ball Earth

Snow ball earth was a hypothesis, which stated that some hundred million years ago the whole planet earth including tropical regions was frozen for around ten million years. Yesterday I was watching a tv program. They proved this is no longer a hypothesis. It really existed. They answered all the questions like how life didn’t extinct and how ended except one, which is how it started.

Cool!

Here is more interesting details with an important observation of mine regarding the survival of life during the millions of years of snowball Earth:

Guess what!!! I have already discovered, regarding this Snowball Earth, that both geologists and biologists didn't know an important recent discoveries about life, which doesn't always depends on sun light.Recently hot springs have been discovered on the ocean floor. The hot springs contain chemicals to sustain microscopic life completely independent fom sun light. There is more in the link bellow:

Since 1977, other hot springs and associated sea life have been found at a number of sites along the mid-oceanic ridges, many on the East Pacific Rise. The waters around these deep-ocean hot springs, which can be as hot as 380 °C, are home to a unique ecosystem. Detailed studies have shown that hydrogen sulfide-oxidizing bacteria, which live symbiotically with the larger organisms, form the base of this ecosystem's food chain. The hydrogen sulfide (H2S--the gas that smells like rotten eggs) needed by these bacteria to live is contained in the volcanic gases that spew out of the hot springs. Most of the sulfur comes from the Earth's interior; a small portion (less than 15 percent) is produced by chemical reaction of the sulfate (SO4) present in the sea water. Thus, the energy source that sustains this deep-ocean ecosystem is not sunlight but rather the energy from chemical reaction (chemosynthesis).http://pubs.usgs.gov/gip/dynamic/exploring.html

''...During that time, the entire Earth was encased in ice up to a kilometre thick.''?

Know anymore info on about the ''...strange creatures were discovered...''?

No strange creatures, except microscopic life, which depended on sun light and the ecosystem around hot springs on the ocean floor, which scientists missed during the debate about the survival when the earth completely covered by ice for millions of years.
