What’s the oldest fossil in the American Museum of Natural History?
On display is not only our oldest fossil, but one of the oldest fossils yet known on Earth. In the Hayden Planetarium’s Cosmic Pathway, you can see a stromatolite from the Warrawoona Group of Western Australia that is 3.45 billion years old. Stromatolites are structures built by single-celled bacteria and the Warrawoona specimen comes from a time when life was exclusively bacterial.
