What does paleobiology mean?
Paleobiology is the branch of biology that investigates ancient life through fossils and related evidence preserved in the Earth. By examining the structure, age, distribution, and environmental context of fossils, paleobiologists reconstruct how organisms lived, evolved, and interacted in former environments. The discipline draws on biology, geology, ecology, and evolutionary science, making it valuable for understanding both the history of life and patterns that may be relevant to present-day ecosystems. It can also contribute to broader scientific questions about mass extinctions, climate change, species migration, and the relationships among living organisms. For general readers, the word most often appears in museum exhibitions, university departments, research articles, and descriptions of fossil-based scientific investigations.
nounThe branch of biology concerned with the study of ancient life, especially through the scientific examination of fossils. It uses evidence from the past to investigate the evolution, ecology, and distribution of organisms in earlier geological periods.
- The scientific study of ancient life through fossils and other evidence from the geological past.
"The museum's paleobiology exhibition explains how fossils reveal the history of life on Earth."
"Paleobiology provides important evidence about how species adapted to changing climates."
"Her research in paleobiology focuses on the evolution of marine mammals."
The plural is uncommon; the field is normally referred to as paleobiology.
"The course compares paleobiologies from different geological regions."
Every fossil is a time capsule: paleobiology uses the remains of ancient organisms to reconstruct the world they once inhabited.

Where does paleobiology come from?
The word combines the Greek-derived prefix paleo-, meaning “old” or “ancient,” with biology, which comes from Greek bios, “life,” and -logy, from logos, “study” or “science.” Its development reflects the modern scientific study of fossils and ancient organisms. Related terms include palaeontology, which has a parallel formation and comes from the same Greek elements.

How paleobiology is actually used
The term is primarily academic and scientific. It overlaps closely with paleontology but tends to emphasize biological questions about ancient organisms, such as evolution, adaptation, ecology, and biodiversity.
Easily confused with paleobiology
Paleobiology studies ancient organisms and their biological characteristics, while paleontology more broadly studies all aspects of ancient life, including fossils, geological context, and evolutionary history.
Biology studies life in general, whereas paleobiology focuses specifically on organisms and biological processes in the ancient past.
