Of course they did you silly goose! All of the Holocene megafauna died because they were hunted by man.
Here are some interesting images of Stegodonts. There are at least 6 different labeled species. They all seem to have rather small ear flaps, although I am not sure how they know this. Frozen carcasses? The pigmy “elephants” on the island of Flores, the one with the “Hobbits” seem to have belonged to this genus. Mostly they have long rather straight tusks, but some seem to do a rather abrupt curve near the end.
