stromatolites & shellsToday we wake up with a beautiful sunrise at the lookout. After breakfast we went on for Shark Bay Peninsula. Our first aim there were the Hamelin Pools with stromatolites, apperently the oldest live-form on Earth. These were the first ones producing oxygen and due to this, kind of made live on land possible. The basis for this are the so called cyanobacteria, which started to build colonies of stromatolites about 3,5 million years ago and then these stromatolites started to produce oxygen. Following this stromatolites were the major live-form on Earth and this way provided the basis for a life on land. 550 years ago plants and animals started to become the main live-form on earth and the stromatolites draw back. Afterwards at some stage the dinausaurs, mamals and finally homo sapiens took their place on Earth.After a nice boardwalk visting different kinds of stromatolites - you can really see little bubbles of oxygen emerging from them - we went to the telegraph station, which was a little bit disappointing. Then we went to Shell Beach - a beach, as the name already says - just consisting of shell. The beach is quite nice - especially as you do not carry around any sand - but the water did not really meet my expectations. I think you can walk in there for kilometers and it is not getting any deeper. So you cannot even swim, as it just is knee's deep. Then we went back to the highway and then a little bit further north for tonights camp. |
