For most scientists all of this seems so obvious that it is difficult to question.It goes against human nature to challenge long held ideas of truth.One way to use plants to learn about palaeoclimates is to identify the nearest living relative of a fossil (Fig.2) and document its environmental tolerance, its relationship with the environment (its Miocene (5 million to 23 million years ago) of the Rhine area of Germany.Although most of the fossils that paleontologists study are several thousands to several billions of years old, there is no absolute minimum age for a biological structure to be a fossil.Paleontologists study fossils and attempt to use them to reconstruct the history of the Earth and the life on it.
A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.
Many of the layers also show a certain specialization.
Some layers contain mostly fish fossils while others contain land-dwelling creatures such as dinosaurs.
Fossils provide us with our only direct record of prehistoric life.
Studying them can help us to reconstruct the anatomy, behaviour and evolution of long-extinct organisms.Perhaps less obviously, fossils are also among the most important sources of information for scientists attempting to learn about past (palaeo) climates and environments — a major focus of research in Earth and environmental sciences, motivated in part by concerns over future climate change. 1), in particular, can be useful for decoding past climate signals.
