Palaeogeography Edit

Palaeogeography is the study of the continents, the oceans and general geography in the times of ancient humans, the animals before them, the dinosaurs, the first creatures living on land, etc. It is most often associated with the physical landscape, but is known as paleogeomorphology if referring to landforms. Palaeogeography is also used in petroleum geology, to understand the evolution of a fossilised creature and helped prove continental drift and plate tectonics correct.

Notes Edit

This list contains dates as listed on Wikipedia. Dates, names and classifications may vary from those listed here.

*The Hadean Eon, Archean Eon and Proterozoic Eons are informally classified together as the Precambrian Supereon.   

**The Gelasian Sub Epoch is currently being disputed over as to whther it should form part of the Pliocene Epoch or Pleistocene Epoch. In this list, the Gelasian Sub Epoch is classified as part of both the Pliocene and Pleistocene.
