Paleozoology, also known as palaeozoology, refers to the study of ancient animal life. The term derives from the Greek words "paleo" meaning ancient and "zoology" meaning the study of animals. While paleozoology is a commonly used term, there are several synonyms that can be used interchangeably, such as paleobiology, palaeobiology, and paleozoography. These terms all refer to the study of prehistoric animals, their anatomy, behavior, and evolution. In addition, other terms such as paleontobiology and paleoenvironmental biology can be used to describe the interdisciplinary field combining paleontology and biology. Regardless of the term used, the study of paleozoology allows us to gain insight into the history and diversity of life on Earth.
