Stromatolites and Pinacles

This weekend I had some spare time to fill in Western Australia so I thought I would take a little drive and check out some of the amazing natural phenomena that abound the ‘Coral Coast’ as this area has been dubbed. With a massively long coastline with warm tropical waters flowing down from the northern Indian Ocean there is a massive variety of sea life including whales (in season), sea lions and so many varieties of sea grass that the coast line is quite putridly fascinating.

So, what is it that I actually went to see? Well an example of the oldest type of living creatures of the world (well slime) which despite being more then 1, 300 million years old can actually be found in quite a few locations around Australia and the world. In one of my little nerding out periods it is interesting to know that Stromatolites and Thromatolites (their very close relative) are communities of bacteria that form large accretions which over time become large rock like structures. These living fossils really don’t look exciting, but when you consider almost identical fossils are the oldest known fossils that is cool.


The second part of my adventure was to visit the Pinnacles, which are fascinating limestone structures sticking out of the sand in a desert like part of the coastline. The pinnacles can be best describes as stalamites that have formed in rock by limestone perculating through fissures instead of through the conventional dripping process. But that is enough science I think.
