Brachyhyops was an early entelodont that roamed across North America long before the emergence of large entelodonts such as Daeodon. There is some confusion about Brachyhyops however regarding another genus called Eoentelodon from Asia. In 2004 Eoentelodon was found to the same genus as Brachyhyops in a study by Lucas and Emry, however a counter to this idea came in 2007 when I. Vislobokova found Eoentelodon to be different. Researchers are currently split as to which theory is correct, something that adds to the confusion to the validity of Eoentelodon, as well as the amount of fossils that can be attributed to Brachyhyops.
