Fossils and relative dating cats intemidating each other
(relative geologic timescale) (b) Absolute Dating Following the discovery of radioactivity in 1895, radiometric dating techniques were developed to determine the absolute ages, i.e. In the succession of strata, each layer represents the geographical conditions that occurred over that area at the time the layer was deposited.
Depending on the day, I’m either on the river with my partner and friends, working on projects around my house, or riding my bike whenever possible through the Connecticut River Valley What are your hobbies?

Strata X to Z were laid down horizontally on top of the older beds.
The table below summarises key features: Gastrioceras listeri is a particularly good example of a ZONE fossil.
