Bitter Springs Group

Precambrian fossil locality in Australia
(Redirected from Bitter Springs)

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.
