Stomping Grounds: Where Mammoths Roamed
As proboscideans spread beyond Africa, about
20 million years ago, they moved across Europe
and Asia into the Americas. Over their six million
year history, proboscideans were able to adapt to
diverse environments: Asian elephants in tropical
forests; woolly mammoths in cold, dry steppes; and
mastodons in temperate woodlands. In the American
West, Columbian mammoths shared the landscape
with other animals and plants. Today, scientists use
clues from the past, such as plant pollen and animal
dung, to help re-create diverse mammoth habitats.
In the early 1800s, the first scientific expeditions to
Siberia collected remains of mammoths. These early
discoveries sparked the public’s fascination with
woolly mammoths and their wintry habitats. In places
like Siberia and Alaska, cold permafrost helps preserve
mammoth remains, and the abundance of woolly
mammoth bones here often leads people to believe that mammoths only lived in snowy, cold climates. But in
fact, during the last Ice Age, many of these areas were drier and less snowy than they are today. Mammoths also
lived in warmer climates, but their remains are often less well preserved in these regions.
During the Pleistocene, or last great Ice Age, mammoths lived alongside many other mammals—many
now extinct. They shared their North American habitat with other herbivores like rabbits, antelopes, camels,
horses and giant ground sloths—the largest herbivores after mammoths and mastodons. Powerful carnivores
also populated these regions: dire wolves, short-faced bears, and American scimitar-toothed cats—the most
successful predators of mammoths.
