          Gasterosteus kamoensis was a stickleback fish of the Miocene. The systematic paleontology of it is:
       
      Actinopterygii Cope 1887
      Neopterygii Regan 1923
      Teleostei Muller 186
      Gasterosteiformes
      Gasterosteidae
      Gasterosteus Linnaeus 178
      Gasterosteus kamoensis Nazarkin, Yabumoto, and Urabe 2013
       
       
          Mikhail V. Nazarkin, Yoshitaka Yabumoto, and Atsushi Urabe wrote an article titled A New Miocene Three-Spined Stickleback (Pisces: Gasterosteidae) from Central Japan. It was publishein 2013 in Paleontological Research 16(4): 318-328. This quote from the abstract says:
       
      Gasterosteus kamoensis sp. nov. is described from the Upper Miocene Minamiimogawa Formation in Kamo City, Niigata, Japan. The new species represents the oceanic complete morph. It is characterized by: short and high ectocoracoid; presence of posttemporal bone; fully developed pelvic girdle with convex margin; wide and not tapering posterior process of pelvic bone; four dorsal spines; comparatively long spines in dorsal, pelvic and anal fins; and large body size, apparently exceeding 130 mm in standard length. Gasterosteus kamoensis sp. nov. is the third nominal fossil species of the genus described from East Asia, along with freshwater G. orientalis Sytchevskaya and the marine G. abnormis Gretchina. Together, these discoveries demonstrate the wide distribution and morphological and ecological diversity of this genus during the Miocene in the northwestern Pacific.
