Stromatolite is a three million year old fossil, sometimes called Crocodile Jasper, due to the crocodile markings created by blue/green algae or cyanobacteria.
Stability, time and tide cycles to do with personal biorhythms. Stromatalite helps the lungs of the human and plant kingdoms and stops one drifting too far away from their roots. It can become a shamanic teacher if you allow it in and can listen to it. Try placing a smooth piece along the spine from the lower to the hollow of the back of the neck. During the day a piece can be taped with ‘micropor’ tape to the base of the spine. It soon warms up and stops feeling strange! This will pull negative energy down the spine away from the neurotransmitters of the brain. It is believed to ground and dissipate negative patterns that have lodged there. New theories are that negative experiences that have happened in this life time or past lives have placed markers within the aura.
