Scientists performed detailed 3D reconstructions of fossils discovered in Scotland.

Cyanobacteria, commonly known as blue-green algae, are the earliest known life forms on Earth. They are responsible for the Earth’s transition from a carbon dioxide-rich atmosphere to the present relatively oxygen-rich atmosphere due to oxygenic photosynthesis.

Ubiquitously found in ponds, lakes, water streams, rivers, and wetlands, they have played a significant role in shaping life.
