Proboscidea (meaning "trunked beast") is an order containing only one familiy of living animals, Elephantidae, the elephants, with three living species (African forest elephant, African bush elephant, and Asian elephant).[1]
During the period of the last ice age there were more species. They included a number of species of the elephant-like mammoths and mastodons.
The oldest proboscidean dates from the early Palaeogene period, over 50 million years ago. The evolution of the elephant-like animals mainly concerned the proportions of the cranium and jaw and the shape of the tusks and molar teeth. These were adaptations to various kinds of vegetable. food
