动物化石 - Lot of 3 stromatolites (没有保留价)

We offer you a remarkable lot of three natural stromatolite specimens, presented as true sculptures of nature and accompanied by elegant display stands (included).
are among the oldest known records of life on Earth. These fascinating structures are biological formations created by colonies of microorganisms, primarily cyanobacteria, whose activity led to the gradual accumulation of layered mineral deposits over billions of years.
Formed during the earliest stages of our planet’s history, stromatolites date back to the , approximately 3.5 to 3.8 billion years ago. At that time, Earth was an extreme environment, characterized by high temperatures and chemically challenging conditions such as saline and alkaline waters—similar to those found in volcanic regions today.
These specimens are not only visually striking, with their natural banding and organic shapes, but also hold profound scientific significance. The study of stromatolites has played a crucial role in understanding the origin of life and continues to inspire the search for simple life forms on other planets.
