What does palaeobiology mean?
Palaeobiology is the biological study of life in the past, with fossils serving as its principal evidence. Researchers use fossilized remains and traces of organisms to investigate their anatomy, evolutionary relationships, distribution, and interactions, often in conjunction with geology, archaeology, and ecology. The field is especially important for reconstructing the history of life and understanding major changes in biodiversity across deep time. Its name combines the classical element “palaeo-,” meaning “old” or “ancient,” with “biology,” the scientific study of living organisms. The related discipline of palaeontology addresses the broader history of life and the fossil record, while palaeobiology places particular emphasis on the biological characteristics of ancient organisms. In American English, the word is also commonly spelled paleobiology.
nounThe branch of biology concerned with the study of organisms that lived in the past, especially through the scientific examination of fossils. It seeks to reconstruct ancient life and its biological relationships.
- The scientific study of past organisms, especially using fossils to investigate their anatomy, evolution, distribution, and relationships with other life.
"Palaeobiology provides important evidence about how species have evolved across millions of years."
"The fossil revealed new evidence about the evolutionary history of early mammals, contributing to research in palaeobiology."
"Her course in palaeobiology examines how ancient environments shaped the development of marine organisms."
The plural is uncommon because the word normally denotes a branch of study rather than multiple organisms or examples of the discipline.
"The history of palaeobiologies encompasses research on many prehistoric groups of organisms."
Every fossil is a time capsule: palaeobiology turns its bones, shells, and impressions into evidence of how life evolved.

Where does palaeobiology come from?
Palaeobiology combines the combining form “palaeo-,” derived from Greek palaios, meaning “old” or “ancient,” with biology, from Greek bios, meaning “life,” and -logia, denoting the study of a subject. The compound refers to the study of ancient living organisms through their fossil remains. Its spelling reflects the traditional use of “ae” in British English, whereas “paleobiology” is the standard American spelling. It is closely associated with palaeontology, which uses the same Greek combining form.

How palaeobiology is actually used
The term is primarily used in academic and scientific contexts. British spelling uses “ae”; American spelling commonly uses “e.” It overlaps with palaeontology but more specifically emphasizes the biological study of ancient organisms.
Easily confused with palaeobiology
Palaeobiology studies ancient organisms and their biological processes, while palaeontology more broadly studies the history of life through fossils and the rock record.
