Dating different fossil technique
Some paleontologists study the ecology of the past; others work on the evolution of fossil taxa.
For additional information on the subdisciplines of paleontology, read our "What is paleontology? Archaeologists primarily work with human artifacts objects that have been made by humans and with human remains.
Radiometric dating and many other techniques are used to support the idea that this transformation process took tens and hundreds of millions of years.Anthropologists work with humans their cultures, societies, languages, and ways of life, in addition to their bones and artifacts.Some paleontologists do study the fossil record of humans and their relatives.This means that plants can be used as proxies for the terrestrial conditions that prevailed when they were alive: data from fossil plants can be compared with records based on marine organisms and chemical isotopes to reconstruct past climates.Several methods have been developed that help us to interpret the climate signals stored in the plant fossil record; the most important of these are outlined below.
