A Presumptive Fossilized Bacterial Biofilm Occurring in a Commercially Sourced Mars Meteorite

Milton Wainwright, Christopher E Rose, Tareq Omairi, Alexander J Baker, Chandra Wickramasinghe and Fawaz Alshammari

A commercially sourced Mars meteorite sample was found to contain a presumptive fossilized bacterial biofilm composed of a wide variety of bacteria-like morphologies. We conclude this presumptive biofilm, and other biomorphs, provide preliminary evidence for the occurrence of fossilised bacteria in a Mars meteorite and therefore that life once existed on Mars.
