Interglacials are a useful tool for geological mapping and for anthropologists, as they can be used as a dating method for hominid fossils. [3] Brief periods of milder climate that occurred during the last glacial are called interstadials. Most, but not all, interstadials are shorter than interglacials.
Generally, stadials endure for a thousand years or less and interstadials for less than ten thousand years, and interglacials last for more than ten thousand and glacials for about one hundred thousand. For a period to be considered an interglacial, it changes from Arctic through sub-Arctic to boreal to temperate conditions and back again.
