Oldest complex organic molecules found in ancient fossils

matograph mass spectrometer. The machine vaporized the solution so that a magnet could separate individual molecules based on electric charge and mass. Computer software then identified the molecules.

Orange and yellow organic molecules emerged, along with several other molecules that the geologists have yet to identify. The off-the-shelf software was only designed to identify common laboratory compounds, O'Malley explained. She would like to generate her own database of fossil organic molecules, and also extract pigments from other marine fossils, including some from sites in Iowa.
