Toadstool Stromatolite




Toadstool Stromatolite
Field research this past summer (2003) has led to the discovery of some beautiful structural stromatolite. The stromatolite is from the Lower Ordovician, Oneota Formation, and is approx. 495 million years old. This stromatolite shows exquisite maze-like surface details…many resembling raised toadstools.

The intricate patterning it has is very naturally artistic. It is important to remember that this is the actual living surface of stromatolite reef. Because of the unique growth structure and field observations, we suspect that this form developed in quite shallow lagoons far removed from the often violent reef front. This is truly an amazing and eye-catching growth form! Specimen weighs 7 pounds and measures approx. 24cm x almost 8cm in height at the highest point.
