AI-assisted summary
Description from the seller
Fossil colonial stromatolite - Microbial mat of cyanobacteria - One of the oldest fossils.
Description:
Fossil of botryoidal/colonial stromatolite, formed by colonies of photosynthetic cyanobacteria that built the planet's first reefs and generated the atmospheric oxygen. Irregular abstract-shaped specimen with 7-8 visible stromatolitic domes/cuppolas, with a very pronounced eye-of-needle concentric growth structure - lamination visible in circles.
The color is reddish-brown - ochre, due to iron oxidation of the sandstone matrix. Wavy laminar structure typical of microbial growth.
Type: Domal stromatolite - Collenia/Conophyton-type colonies - Stromatolitic limestone
Locality: Region of Atar, Mauritania / Anti-Atlas Morocco - Sahara
Geological Age: Precambrian - Neoproterozoic - Approx. 600 - 800 million years - subtidal marine
This fossil predates the dinosaurs, predates the trilobites. It is the origin of life.
Measurements:
Height: 140 - 16.5 cm
Width: 9.5 cm
Conservation:
Good / Very good. Natural, without restoration, without resin, without paint. Original laminations intact, unpolished. Natural irregular edge. Piece stable, solid.
Scientific Note:
Stromatolites are the oldest fossil evidence of life on Earth, about 3,500 million years ago
