Most Ancient Life on Earth

They are called "thrombolites" and they were 2 km from our B&B in Flower's Cove.  They are a microbial community that we now see as rounded rock structures.  But they really look 'organic', if that word can be used for rocks.  They date as far back as 3.5 billion years ago (yes that's 3.5E9) and represent the first forms of life on this planet.  Apparently they are quite rare (the only other known site is in Australia) so it is rather amazing that this is not a nationally protected site.
