Uncover the fascinating story behind an ancient fossil, a window into the past of life on Earth.

About this subject

Ancient fossils are remains or traces of organisms that lived in the past, preserved in sedimentary rocks. They provide valuable information about the evolution of life on Earth, including the diversity of species that existed and the environmental conditions in which they lived. The formation of fossils is a rare process that requires specific conditions, such as the rapid burial of organic remains and the presence of minerals that can replace them over time. The oldest known fossils date back to around 3.5 billion years ago, during the Eoarchean, and include microorganisms such as bacteria and archaea.
