How are fossils dated using radiometric dating

Many of the layers also show a certain specialization.

Some layers contain mostly fish fossils while others contain land-dwelling creatures such as dinosaurs.

If the geologic column truly represents a series of closely spaced catastrophic burial events instead of long ages of time, how can this feature be explained?

Radiometric dating and many other techniques are used to support the idea that this transformation process took tens and hundreds of millions of years.

Single celled organisms make their first appearance in the lowest layers followed by multicelled ocean bottom-dwelling creatures like sponges and worms etc.

Higher up come creatures like bony fishes, then land plants and animals, then birds and larger land animals.

Some habitats are clearly more susceptible to the preservation of fossils.

If those specific habitats are not occupied by a particular kind of creature, it may not be preserved in the fossil record even though it is still alive and well in some other habitat.
