Furo is an extinct genus of marine ray-finned fish, belonging to the order Ophiopsiformes or Ionoscopiformes, known from the Early Jurassic of England. Other species from throughout Europe, from the Late Triassic to Late Jurassic, have been previously placed in this genus. [1]

Taxonomy

Life restoration

The type species of Furo, F. orthostomus, was originally named Eugnathus by the Swiss naturalist Louis Agassiz in 1843, [2] but the genus name was changed to Furo by Johannes von Nepomuk Franz Xaver Gistel in 1848 because Eugnathus was preoccupied by the beetle genus Eugnatha. A number of species referred to Furo have been found in the Solnhofen Formation of Bavaria. [3] 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. [4] [5]

The following two species are the only definitive members of this genus: [1]

The following species, previously classified into Furo, are considered valid taxa but likely do not belong in Furo, and need to be classified into their own genera: [1] [7]
