Paleobiology, founded to provide a forum for the greater integration of paleontology and biology, began publication in 1975. Paleobiology publishes original articles that emphasize biological or paleobiological processes and patterns including: speciation, extinction, development of individuals and colonies, natural selection, evolution, and patterns of variation, abundance and distribution of organisms in space and time. Papers concerning recent organisms ans systems are also included if they aid in understanding the fossil record and the history of life. In addition to research articles of moderate length, Paleobiology provides an outlet for shorter and longer pieces. The Matters of the Record section features succinct, up-to-date discussions of new discoveries, reviews of recent conceptual advances, and brief syntheses of important topics. Paleobiology also publishes short book essays in its Book Review section. In 1999, Paleobiology began publication of an occasional series, Paleobiology Memoirs, which provides an outlet for longer works on the same topics covered in regular research articles.
