Palaeontology and palaeontologists

In contrast to evolutionary biology, which is concerned with the general laws of the development of life, palaeontology is concerned with the specific history of the alternation of species on the Earth. The main source of palaeontological knowledge consists in fossils, ancient remains of the bodies of organisms (or rather their hard parts) or remains left by their activities (paths, faeces) that have escaped decomposition by happy circumstances and have remained in better or worse preserved form to the present day.
