The oldest known fossils are stromatolites, which are formed by the layering of microbial mats, primarily cyanobacteria.

Discovered in Greenland, these microfossils date back approximately 3.7 billion years, representing some of the earliest evidence of life.

Found in Canada, these fossils are believed to be about 3.77 billion to 4.28 billion years old, potentially the oldest evidence of life on Earth.

This is one of the oldest known eukaryotic fossils, dating back to about 2.1 billion years ago, found in Michigan, USA.

These are some of the oldest known eukaryotic microfossils, found in sediments dating back to around 1.8 billion years ago in Australia and China.

Discovered in India, these fossils are about 1.6 billion years old and represent some of the earliest complex multicellular organisms.
