We offer you sculptures of nature, true evidence of the creation of life on Earth. Stromatolites are biological constructions formed by the activity of bacterial colonies. The discovery of these structures has renewed the search for “simple” life forms that could exist on other apparently hostile planets. When Earth itself was inhospitable—characterized by high temperatures and saline and alkaline waters, such as those found in volcanic environments—the first traces of life are estimated to have appeared between 3.5 and 3.8 billion years ago, in microbial form. This listing is a lot of 3 stromatolite specimens, each a unique and authentic witness to the earliest chapters of life on our planet.
