Overview
Excerpt from Cenozoic Mammal Horizons of Western North America: With Faunal Lists of the Tertiary Mammalia of the West

It is proposed, according to the ruling of the International Geo logical Congress and the old practice of invertebrate paleontologists, to use the word zone for the faunistic levels of such geologic forma tions or groups as may be synchronized by the presence of certain distinctive animals. Thus we may speak of the Uintatherium zone of the upper Bridger formation or of the lower Washakie. The word beds, previously used in the same sense, is liable to cause confusion because it is used also for formations.
