7" Polished Stromatolite (Kussiella) Slab - Canada
This is a beautiful polished slab of Paleoproterozoic stromatolites (Kussiella cf. kussiensis) that was collected from a small island at the northeast end of Blanchet Island, within the Northwest Territories of Canada. These precambrian stromatolites have been dated at roughly 1.88 billion years old. The slab has been polished to a mirror finish and comes with an acrylic display stand.
About Stromatolites
Stromatolites are fascinating, ancient rock formations created by the activity of cyanobacteria and other microorganisms. These layered, mound-like structures represent some of the earliest evidence of life on Earth, dating back over 3.5 billion years. Often found in shallow, warm waters, stromatolites form as layers of sediment and minerals are trapped and bound by microbial mats, gradually building up over time into unique, textured shapes.
Visually, stromatolites can range from smooth, rounded forms to intricate, banded structures, with colors that span earthy reds, browns, greens, and grays. Each layer captures a record of environmental conditions at the time of its formation, making stromatolites an invaluable source of information for scientists studying Earth’s early history and the origins of life.
