Illiger, 1811

During the period of the last ice age there were more, now extinct species, including 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.

FamiliesEdit

Present-day elephants are the survivors of a once larger and more varied family.
