Etymology: Palaeobiology is a compound with a precise, recent history. Its first half, "palaeo-", comes from Ancient Greek "palaiós", meaning "old" or "ancient", which itself grows from "pálai", "long ago". Its second half, "biology", is a far younger coinage: the word "biologia" appeared in New Latin in the early 1800s, built from Greek "bíos" (life) and "-logía" (the study of), and English took "biology" from it. Ancient Greeks had no word for the discipline, because the science of life and the science of ancient life only came together once these pieces existed. The combination itself is a modern invention, made by simply joining "palaeo-" to "biology". The result names the study of organisms that lived in the distant past, and of how they related to one another and to their surroundings, through the evidence they left in rock.
