Origin and Etymology of dinichthys

borrowed from New Latin, from din- dino- + -ichthys-ichthys
Note: Genus name introduced by the American physician and geologist John Strong Newberry (1822-92) in “On Some Remarkable Fossil Fishes, Discovered by Rev. H. Herzer, in the Black Shale (Devonian) at Delaware, Ohio,” Proceedings of the American Association for the Advancement of Science, Sixteenth Meeting, August, 1867 (Cambridge, Mass., 1868), p. 146: “Dr. Newberry exhibited to the section different portions of the head of a gigantic fish, to which he had given the name of Dinichthys Herzeri, and which, he said, from its size and structure, deserved the same distinction among fishes that Dinotherium and Dinornis enjoy among mammals and birds.”
