Etymology: Limnocyonids belong to the family Limnocyonidae, named after the genus "Limnocyon," which was described by the American paleontologist Edward Drinker Cope in 1872. Cope built the name from two Greek parts: "limnē," meaning "marsh" or "lake," and "kyōn," meaning "dog." The name therefore means "marsh dog," a reference to the place where the earliest specimens were found, in the Eocene fossil beds of the American West. Cope's naming was typical of his era, when fossil finds were labelled with descriptive Greek and Latin compounds. The plural form simply follows the Latin-style family suffix "-idae," which zoologists add to the stem of a genus to name a family, and "-id" is the singular form of that suffix. So the noun is a plural of "limnocyonid," one member of this extinct group. Despite the name, these animals were not true hyenas or dogs. They were early members of the broader group of mammals called creodonts, carnivorous relatives of later meat-eaters that lived in the Paleogene period, roughly 56 to 34 million years ago.
