dc.description.abstract "The fossil genus Knightia is revised; bK. eocaena Jordan, 1907, and K. alta (Leidy, 1873) are redescribed, and sK. vetusta, new species, is described from the Middle Paleocene Tongue River Formation of southeastern Montana. Knightia is placed in the Pellonulinae. It was found that the known geologic range of aKnightia is Middle Paleocene to Middle Eocene and its geographic distribution appears to be western North American, or possibly Pacific continental (western United States and possibly China). Knightia is known only from deposits of probable freshwater origin. A new clupeid genus, pGosiutichthys, is described from early Middle Eocene deposits of the Green River Formation in Wyoming. Gosiutichthys parvus, new species, is a small herring that, unlike iKnightia (the other Green River clupeid), has two supramaxillary bones, thin transparent scales, and several other differentiating characters. The interrelationships of G. parvus with other clupeids are not known, but it is placed provisionally in the poorly defined subfamily Clupeinae. The presence of two supramaxillary bones prevents its placement in Pellonulinae as the subfamily is currently defined"--P. [1]. en_US
