    Abstract

    The possibility of pseudofossils is a well-known obstacle to the identification of fossilized microorganisms (Cloud, 1973; Westall, 1999) and distinguishing abiotic from biotic origins is still a hotly debated topic (Dalton 2002; Schopf et al., 2002; Brasier et al., 2002). Here we report silica-carbonate aggregates, so-called ‘biomorphs’ that mimic—both morphologically and chemically-primitive microfossils.
