Large Stromatolite Fossil Algae 20 lbs Wyoming

Stromatolites are fossilized algae colonies which scientists think we might find for life on Mars. They have been determined to be the oldest and longest continually surviving life forms on Earth.

It shows the characteristic botryoidal structure (lumpy - like a bunch of grapes, or a "brain" -like structuring) of the outer surface of the ancient colony. Other edges show the layered structure created by layer after layer of continued algael microbial mat growth.
