Fossilised animal - 26 cm - 18 cm

Designation: Fossil stromatolite matrix / natural geological sculpture. • Origin: Morocco (often the Sahara Desert, Atlas). • Geological age: Ordovician to Precambrian (depending on the exact formation, estimated between 450 million and 3.5 billion years). • Scientific & aesthetic interest: Stromatolites are among the oldest traces of life on Earth. They were built by colonies of cyanobacteria (photosynthetic microorganisms) that captured sediments to form these unique concentric laminated layers. Highly sought after as interior decoration pieces or cabinets of curiosities. • Condition: Raw and natural on the back, often cleaned or lightly polished on the surface to highlight the geometric growth rings.
