'Gomphotherium' is an extinct genus of proboscideans within the family Gomphotheriidae. These animals were more primitive relatives of modern elephants, mammoths and mastodons. They possessed elongated lower jaws and unique tusk arrangements. Think of them as the experimental prototypes of the elephant world. ๐งช They lived from the Oligocene to the Miocene epochs, found in various parts of the world. Their fossils give us insight into proboscidean evolution.
