Stromatolites are one of the Earth's earliest life forms. This giant stromatolite display specimen is a cross-section cut from the Green River formation from a bulbous columnar microbial mat in Wyoming. This stromatolite is thick cut, has terrific exterior "crust," and is shaped like a mushroom.

Size: 13 1/2" W X 10" H X 3/4" D, Weight: 4.7 lb.; The specimen is unaltered and is in its most natural form. The first picture is of the front, the second of the back, the third is side-on, and the 4th is a DIFFERENT specimen from the same columnar stromatolite that shows the same rind that can be seen on the edge of the stromatolite for this listing.

Ships with Certificate of Authenticity, display stand (shown), tag, and tag stand.

Here is a very rare opportunity to get a dynamically large specimen from the ancient Lake Gosiute, Wyoming region, one of the most incredible stromatolite locals in the world.
