Bitter Springs Group

Bitter Springs Group is a Precambrian fossil locality in Australia, which preserves microorganisms in silica.^[1] Bitter Springs type preservation ceased in the late Precambrian with the coming of silicifying organisms.^[2] Preserved fossils include cyanobacteria microfossils.^[3]

Bitter Springs is pretty much in the centre of Australia, in the south of the Northern Territory.
