[1]A report of the research, entitled ‘Changing the picture of Earth's earliest fossils (3.5-1.9 Ga) with new approaches and new discoveries’, is published in PNAS. The resolution of a decades-old debate about the oldest fossils on Earth can reinvigorate the search for early life and open up a window on the strange world of ancient microorganisms.

Analyses by secondary ion mass spectroscopy (SIMS) of 11 specimens of five taxa of prokaryotic filamentous kerogenous cellular microfossils permineralized in a petrographic thin section of the ∼3,465 Ma Apex chert of northwestern Western Australia, prepared from the same rock sample from which this earliest known assemblage of cellular fossils was described more than two decades ago, show ... chert and flint, very fine-grained quartz ( q.v. ), a silica mineral with minor impurities. Several varieties are included under the general term chert: jasper, chalcedony, agate ( qq.v. ), flint, porcelanite, and novaculite. Flint is gray to black and nearly opaque (translucent brown in thin splinters) because of included carbonaceous matter.
