What is Paleontology?
Paleontology or palaeontology is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene Epoch. It includes the study of fossils to determine organisms’ evolution and interactions with each other and their environments.
What are the things paleontology includes?
Paleontology includes geological time scales, prehistoric era, animals and biodiversity
Geologic time scale
The geologic time scale is a system of chronological dating that relates geological strata to time. It is used by Geologists, Paleontologists, and other Earth scientists to describe the timing and relationships of events that have occurred during Earth’s history.
These are the time scales

Prehistoric animals
There are many animals which existed in this world before. We can’t describe them all. So we are going to see animals that existed in Triassic to Cretaceous period
