Range of Prosynthetoceras based on fossil record

Prosynthetoceras is an extinct genus of Artiodactyla, of the family Protoceratidae, endemic to North America. It lived from the Early to Middle Miocene 20.6—13.6 Ma, existing for approximately 7 million years. ^[1] In appearance, Prosynthetoceras looked much like Syndyoceras, Kyptoceras, and Synthetoceras with three horns, one on the snout, and two above the eyes.
