"Lost Lagoon Unveils Ancient Living Fossils and Clues to Earth's Origins"
Scientists have discovered a hidden lagoon system in Argentina containing stromatolites, giant layered rocks formed by cyanobacteria. These stromatolites provide insight into Earth's earliest forms of life, dating back 3.5 billion years. The fossils found in the lagoons represent Earth's earliest macrofossils in a rare environment. The discovery also has implications for the possibility of life on Mars, as stromatolites could have formed through anoxygenic photosynthesis, similar to what may have occurred on the red planet. The study of these ancient stromatolites will help us understand Earth's early history and shed light on the potential for life on other worlds.
