Bitter Springs Group is a Precambrian fossil locality in Australia, which preserves microorganisms in silica.[2] Its preservational mode ceased in the late Precambrian with the advent of silicifying organisms.[3]

Fossil stromatolites from the Bitter Springs Group

Preserved fossils include cyanobacteria microfossils.[4] This locality also has been claimed to contain eukaryotic green algae[5] preservation, though this interpretation is debated.
