Do you know what a Stromatolite is? I didn’t until I read chapter 19 in Bill Bryson’s book “A Short History of Nearly Everything” – which I found highly interesting.
Well a Stromatolite is one of the first complex living organisms that arrived on the scene about 3.5 billion years ago; which is quite a long time ago considering the earth is only 4.5 billion years old.
The interesting thing is that I found a press release from the NY State Museum which tells us that the Adirondacks a few billion years ago were teaming with them. Some of the more complex ones have been found in present day Washington County.
“New York has the oldest animal fossils in the eastern United States – dating to a time that takes eight zeros to express. The (museum had an) exhibition … of these, a star-like trail discovered in Washington County. (NY has) fossils that are even older, stromatolites made by blue-green bacteria living more than a billion years ago in the seas of what are now the Adirondacks.”
Next time you’re out for a walk, you’ll know what to look for.
