Dating the fossil record activity
Many of these organisms have left their remains as fossils in sedimentary rocks.
Geologists have studied the order in which fossils appeared and disappeared through time and rocks. Fossils can help to match rocks of the same age, even when you find those rocks a long way apart.
So, there are different types of fossils: Obviously fossils became more common after the appearance of hard parts (shells, teeth, bones …), 543 million years ago (Cambrian Explosion).
The fossil record prior to this period is very scarce.
But when laid on the ground, they are fixed to the position that the north magnetic pole was at the time.
If we look at what coordinates are oriented such minerals at the site, we can associate it with a particular time.
The method of reading the order is called stratigraphy (layers of rock are called strata).
Students begin by observing a photograph and a diagram of rock layers near Whanganui, watch an animation about how the layers were formed, then use an interactive labelling diagram to work out the order in which the rocks were created.Evolutionists believe that the fossil record supports their theory of the slow and gradual evolution of life from amoebas to astronauts.Creation scientists reject this view and choose to accept the biblical version of the origin of life on earth.we often make reference to fossils to explain the past of living beings. Fossils are remnants (complete or partial) of living beings that have lived in the past (thousands, millions of years) or traces of their activity that are preserved generally in sedimentary rocks.
Have you ever wondered how science knows the age of a fossil? If you think of a fossil, surely the first thing that comes to your mind is a dinosaur bone or a petrified shell that you found in the forest, but a fossil is much more.Correlation can involve matching an undated rock with a dated one at another location.Suppose you find a fossil at one place that cannot be dated using absolute methods.For example, microscopic dinoflagellates have been studied and dated in great detail around the world.
