  ## Taxonomy
  
  The type species of Furo, F. orthostomus, was originally named Eugnathus by the Swiss naturalist Louis Agassiz in 1843, but the genus name was changed to Furo by Gistel in 1848 because Eugnathus was preoccupied by the spider genus Eugnatha. A number of species referred to Furo have been found in the Solnhofen Formation of Bavaria. The type species of Ophiopsis, O. muensteri, was mistakenly referred to Furo by some authors, but recent studies have indicated that the Furo and Ophiopsis type species are distantly related.
