The fossils in this group were discovered by
Arthur Hugh Hickman in 1983 in
Warrawoona, , a region on the
Pilbara craton in the northern part of
Pilbara province. Whether or not the fossils were authentic was disputed in the past, as
abiotic processes could not be ruled out. Currently the fossils are thought to be of biological origin, however there is no conclusive evidence of fossilized organisms in the formation, and whether the lines in the rock are fossilized
stromatolites. The rocks also include
felsic volcanic rocks. == See also ==
