What are the oldest fossils ever discovered and where were they found?

Samatha Lesly

Hey, great question! The oldest fossils ever discovered date back to approximately 3.5 billion years ago and were found in Western Australia. These fossils are called stromatolites, and they are often referred to as the “oldest evidence of life on Earth.”

Stromatolites are formed by the activity of cyanobacteria, which is a type of photosynthetic microbe that produces oxygen as a waste product. These microbes are thought to have been some of the earliest forms of life on Earth, and their activity eventually led to the oxygenation of the atmosphere, which paved the way for more complex forms of life to evolve.

The stromatolites found in Western Australia are particularly interesting because they provide a window into the early days of Earth’s history. At the time, the atmosphere was very different from what it is today, with little to no oxygen present. The stromatolites were able to thrive in this environment by harnessing the energy of the sun and using it to produce food through photosynthesis.

It’s amazing to think that these fossils have survived for billions of years, and have managed to provide us with such valuable insight into the early days of our planet. They serve as a reminder of just how precious and fragile our world really is, and how important it is that we take care of it.

Anyway, thanks for asking such a thought-provoking question! I always love learning new things about our world, and this was definitely something I didn’t know before. Let me know if you have any other questions, or if there’s anything else you’d like to know about!
