Cool fossilized nervous system

Hey guys,

So recently there was a 520-million-year-old fossilized nervous system that was discovered. Similar to modern arthropods, this fossil has nerve cords which are similar to spinal cords in vertebrates. They even used fluorescence microscopy to see the evolution of the nervous system and confirming that the ganglia are individual nerves that are fossilized as carbon films. Cool stuff.
