Eons, Eras,Epochs, and period
Each era on the scale is separated from the next by a major event or change. Different spans of time on the time scale are usually delimited by major geological or paleontological events, such as mass extinctions.

Permian Period.
The Permian Period was ended by the Permian/Triassic Extinction Event, which wiped out 90% of the species on Earth at that time.
The geological time scale organizes a long period of time.
Permian Period was from 299 million years ago to 250 million years ago
dimetrodon was the dominANT SPECIES OF THE permian period
IT encompasses all of the geological time period that have happened since the begin of time
At the end of the Permian Period which was about 251 million years ago
Uplift and erosion over a long period of time are some of the various geologic events that can occur to eventually destroy a part of the rock record
the mass extinction
Quaternary.
