Elephant
The gomphotheres lasted  a long time, and were hunted by modern man. There was a change in plant resources, with the reduced forests and extended grassland. This favoured specialist grass feeders over generalist eaters. This change in the dietary supply was one of the factors which forced gomphotheres toward extinction in the late Pleistocene in South America. The remaining population probably succumbed to climatic change and/or human predation around the time of the Holocene margin.
