  1. Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4.

  2. Although the recognition of fossils goes back hundreds of years, the systematic cataloguing and assignment of relative ages to different organisms from the distant past — paleontology — only dates back to the earliest part of the 19th century.

  3. The Age of Dinosaurs was so many millions of years ago that it is very difficult to date exactly.

  4. This diagram shows a selection of rock layers, or stratigraphic columns, from the Koobi Fora geologic formation on the eastern shore of Lake Turkana in Kenya.

  5. The age of fossils can be determined using stratigraphy, biostratigraphy, and radiocarbon dating.
