Large Stromatolite 20 lbs. Wyoming

Stromatolite Ancient Microbial Mat Green River Wyoming

Stromatolites are fascinating geological formations created by the activity of microorganisms. Here’s a simplified explanation of how they form:

1. Microbial Mats: The process begins with the growth of microbial mats in shallow water environments. These mats are composed primarily of cyanobacteria, which are photosynthetic microorganisms.
2. Sediment Trapping: As these microorganisms photosynthesize, they trap and bind sediment particles from the surrounding water. Tidal activity is generally involved in this process.
3. Growth Over Time: These layers build up gradually, creating banded patterns characteristic of stromatolites. The process continues as long as the microbial mats remain active, forming more complex structures.

Premium Museum-Grade Specimen

This exquisite museum-grade stromatolite specimen hails from Green River, Wyoming, dating back to the Eocene epoch, approximately 50 million years ago. Known as Chlorellopsis coloniata Reis, this specimen showcases the characteristic botryoidal structure (resembling a bunch of grapes or a brain-like formation) on its outer surface. The edges reveal the layered structure formed by successive layers of algal microbial mat growth.

Sometimes this type of stromatolite is called a "brain stromatolite" because it resembles the folds of a human brain. Regardless, it has interesting features, great color and dynamic details.
