The study of fossils is called "paleontology." Paleontology encompasses the examination of the history of life on Earth through the analysis of fossilized remains, tracks, and traces left by organisms. By studying fossils, paleontologists can reconstruct past environments and understand the evolution of various life forms. This field combines elements of biology, geology, and archaeology to uncover how life has changed over millions of years. It provides critical insights into extinct species, ancient ecosystems, and the processes that have shaped the biodiversity we see today.
