The European Land Mammal Ages establishes a geologic timescale for prehistoric European fauna beginning 66.5 Ma during the Paleogene and continuing through to the Middle Pleistocene (0.33 Ma). These periods are referred to as ages, stages, or intervals and were established using geographic place names where fossil materials where obtained.

The basic unit of measure is the first/last boundary statement. This shows that the first appearance event of one taxon is known to predate the last appearance event of another. If two taxa are found in the same fossil quarry or at the same stratigraphic horizon, then their age-range zones overlap.
