Pilbaria is a genus of fossil stromatolite-forming cyanobacteria from the Paleoproterozoic era 2.3 to 1.7 billion years ago.[1] It is named after the Pilbara region of Western Australia where the type specimen was found.[3][2]
Distribution and age[edit]
Fossils of P. perplexa, the type species, have been found in the Wyloo Group of the Pilbara region in Western Australia, aged 1.7 to 2 billion years old and in the Epworth Group of the Coronation and Pine Creek Geosyncline in Canada, aged 1.865 to 2.2 and 2 to 2.3 billion years old.
P. boetsapia and P. inzeriaformis are from Schmidtsdrift Formation of the Northern Cape Province in South Africa, aged approximately 2.2 billion years old.
P. deverella is from the Yelma and Frere formations of the Eeraheedy Group of Western Australia. It is the youngest of the four species, with fossils from these areas aged to about 1.7 billion years old.[1]
