Product Description

Authentic Apex Chert for Sale

This is authentic Apex Chert from Pilbara, Western Australia, and is believed to among the oldest specimens to contain the oldest known fossils on Earth. There is some controversy over Apex Chert - as so many other early life specimens among scientists, certainly not for all of them.

Approximately 3.5 billion years ago, this rock was sediment on the floor of an ancient lake or ocean. Bacteria or algae lived on (and in) the sediment and were trapped and preserved. These fossil bacteria are so small that they can only be seen with a microscope. There have been approximately eleven taxa of prokaryotes found in the Apex Chert. Most are chains of single cells, forming filaments, very much like bacteria and blue-green algae do today found on the floors of modern lakes. These filaments of cells have the same shapes as some structures found in ALH 84001 (a meteorite found in Antarctica believed by some to contain actual life from Mars), which suggests that the structures in the meteorite could also be fossils of bacteria.

This material was legally obtained in a trade with a university.

-The Apex Chert (3.4 Ga) of the Pilbara craton, Australia is known to have preserved eleven taxa of prokaryotes.

- The Gunflint Chert of western Ontario (1.9 to 2.3 Ga) preserves not only bacteria and cyanobacteria but also organisms believed to be ammonia-consuming and some that resemble green algae and fungus-like organisms (see sample on website).

- The 3.2 Ga chert of the Fig Tree Formation in the Barberton Mountains between Swaziland and South Africa preserved non-colonial unicellular bacteria-like fossils (see sample on website).

- The Devonian Rhynie chert (400 Ma) of Scotland has the oldest remains of land flora, and the preservation is so perfect that it allows cellular studies of the fossils (see sample on website).

Note: The Pilbara Craton is an old and stable part of the continental lithosphere located in Pilbara, Western Australia. It is one of only two pristine Archaean 3.6-2.7 Ga crusts identified on the Earth, with the Kaapvaal Craton in South Africa. Both locations may have once been part of the Vaalbara Supercontinent on the continent of Ur.
