PaleoBase represents a unique combination of up-to-date systematic information on an extensive collection of fossil genera, state-of-the-art color digital photographs of representative specimens from The Natural History Museum's unrivalled paleontological collections, and modern relational database technology.

PaleoBase provides an important new tool for the teaching of life history in a wide variety of advanced secondary, undergraduate, and graduate courses (e.g., paleontology, historical geology, stratigraphy, paleoceanography, paleobiogeography). Instructors will find the database a rich resource for lecture presentations, discussions, and laboratory exercises. Students will find PaleoBase an invaluable addition to traditional textbooks, and a key reference source for basic systematic paleontology.
