Abstract: Paleontologists study the past history of life by analyzing fossil remains.The field of paleontology lies on the boundary between two disciplines?biology and geology.Paleontological applications include systematics/taxonomy, evolutionary studies, biostratigraphy, taphonomy, ichnology, paleoecology, and paleoenvironmental analyses.The biological aspects of paleontology support the evolution of life throughout geologic time.The most fundamental fact of paleontology is that organisms have changed throughout the history of Earth and that each geological period has its characteristic forms of life
