The ability to directly date our fossils using the unstable isotope carbon-14 enables us to pair these results with cutting-edge techniques such as stable isotopes, dental microwear, and collagen sequencing to help us understand the factors that influenced the current distributions of much of our flora and fauna before humans changed the landscape.
Pleistocene epoch - pleistocene epoch - pleistocene fauna and flora: the plants and animals of the pleistocene are, in many respects, similar to those living today, but important differences exist. Moreover, the spatial distribution of various pleistocene fauna and flora types differed markedly from what it is at present. Changes in climate and environment caused large-scale migrations of both.
