Quaternary paleogeography — Quaternary Distribution of landmasses, mountainous regions, shallow seas, and deep ocean basins during the Quaternary Period. Included in the paleogeographic reconstruction are the locations of the interval's subduction zones.

The Holocene Epoch is the current, formally recognized interval of geologic time, spanning approximately the last 11,700 years and coinciding with the development of human civilization following the most recent ice age.12

In contrast, the Anthropocene Epoch is a proposed, unofficial interval that some scientists argue should follow the Holocene. While the Holocene accounts for the emergence of humanity as a force on the landscape, the Anthropocene is defined by the period in which human activities—such as industrialization, population growth, and technological advancement—began to fundamentally and substantially alter Earth’s surface, atmosphere, oceans, and biogeochemical cycles.3214

Proponents of the Anthropocene often suggest 1950 as a potential start date, citing the global presence of plutonium isotopes from nuclear testing as a distinct stratigraphic marker. However, the Anthropocene remains an informal designation, and its formalization is subject to ongoing debate within the scientific community regarding its necessity and the criteria for defining its base.25
