Palaeontologian
Palaeontologian is a field of study that focuses on the past life of Earth, as revealed by fossils. Fossils are the preserved remains or traces of organisms that lived millions or even billions of years ago, and can include bones, shells, footprints, and imprints. Palaeontologists use these fossils to understand the evolution of life, reconstruct ancient ecosystems, and learn about the Earth's history.
The discipline encompasses a wide range of sub-disciplines. Vertebrate palaeontology deals with the fossils of animals
Palaeontologists employ various techniques in their research. Fieldwork involves excavating fossil sites and carefully collecting specimens.
