Researchers discovered sled-like drag marks alongside ancient footprints at White Sands National Park in New Mexico .
Indigenous groups of the Great Plains (which includes part of New Mexico ) used travois pulled by dogs (and later horses) to transport their houses, furniture and other possessions at the time of early contact with European colonizers around 500 years ago .
