International audiencePhosphorites are sedimentary formations enriched in Ca-phosphate minerals. The precipitation of these minerals is thought to be partlymediated by the activity of microorganisms. The vast majority of studies on phosphorites have focused on a petrological and geochemical characterization of these rocks. However, detailed descriptions are needed at the sub-micrometer scale atwhich crucial information can be retrieved about traces of past ormodern microbial activities. Here, scanning electron microscopy (SEM) analyses of a recent phosphorite crust from the upwelling-style phosphogenesis area off Peru revealed that it contained a great number of rod-like and coccus-like shaped micrometer-sized (~1.1 μm and 0.5 μm, respectiv...
