Paleontologists are scientists that study the history/existence of past lives by collecting and examining fossils. They use these fossils to determine the history and age an organism has existed. Fossils are remains of dead organisms (plants and animals) which serve as evidence of past lives that have existed on earth in the past. They could include bone remains or footprint of this animals.

Fossils (from bones) are however mostly incomplete because they decompose before they are "stored naturally" by sediments which covers them. When scientists discover this incomplete fossils, they are compared (if there has been similar fossils discovered before then) and are stored and transferred to the lab for examination. This examination includes anatomical comparison (to determine relatedness with other fossils/organisms), carbon dating (to determine age) and data comparison (which includes location and type of soil and habitat).
