The Bitter Springs Group, also known as the Bitter Springs Formation is a Precambrian fossil locality in Australia, which preserves stromatolites and microorganisms in silica. [3] Its preservational mode ceased in the late Neoproterozoic with the advent of silicifying organisms. [4]
Fossils include exceptionally well-preserved cyanobacteria microfossils, as well as multiple stromatolite species, including Linella avis and Inzeria intia. [5] [6] This locality also has been claimed to contain eukaryotic green algae preservation, though this interpretation is debated. [7]
