Comments P.9 bottom paragraph: "Oldest fossil spider—∼300 Myr ago. The oldest known true spiders date back to the Carboniferous age, around 300 Myr ago. Most likely, specimens of Palaeothele montceauensis (Selden) (Mesothelae) are the earliest described fossil species, from the Upper Carboniferous (Stephanian) of Montceau-Ies-Mines, France (primary source)."
