Oldest Fossil Brain Found in Kansas

Iniopt-Reconstruction

When Alan Pradel of the Muséum National d′Histoire Naturelle in Paris CAT scanned a 300-million-year-old fossilized iniopterygian from Kansas, he and his colleagues saw a symmetrical blob nestled within the braincase. This turned out to be the oldest brain found in fossil form, a wholly unexpected and rare discovery.
