Question

What does the geologic time scale confirm about the Cretaceous period?

Answer 1

Geologic Time Scale (GTS) is used by the geologists and the system of the chronological dating relates various geological strata (which are known as stratigraphy) to the time.

The ending of Cretaceous can be defined by K–Pg boundary. It is a geologic signature that is associated with mass extinction that lies between Mesozoic and the Cenozoic eras.
