Spathiurus is an extinct genus ofray-finned fish that lived during theCenomanian in theSannine Formation of Lebanon.[1]
Spathiurus was designated as a member of the familyIonoscopidae in 2020, as it shows the diagnostic features of the group, making it the first member of the family to be known from the late Cretaceous as well as theMiddle East.[2] It is believed to be a sister taxon toIonoscopuspetrarojae, the both are more derived than 'Ionoscopus'cyprinoides, which probably belongs in a different distinct genus.[2] The speciesAmphilaphurus major is currently believed synonymous withSpathiurus dorsalis.[2]
