History of invertebrate paleozoology and simpler sea-dwelling organisms. By far, invertebrate paleozoology is the easiest type of fossil collecting. "Unlike" the difficult-to-analyze and hard-to-interpret fossils of paleobotany (plants) and micropaleontology (microbes), and "unlike" the rarely found and poorly preserved skeletons of vertebrate paleontology, invertebrate fossils are usually both common and simple to identify. This is because many prehistoric invertebrates were hard-shelled mollusks, brachiopods, trilobites, bryozoans, crinoids or corals who were buried amid marine, sediment-preserving conditions; and therefore frequently fossilized. Stone-age people were without doubt the very first fossil collectors. Fossilized echinoderms have been found in Dunstable, Bedfordshire, central England, decorating a long-buried human skeleton;
Man o' War by Page Cooper and Roger Treat, was published in 1950, and is a classic of its kind. Walter Farley, author of "The Black Stallion" series, also wrote a slightly fictional biography of Man o' War in 1962. In 2000, Edward L. Bowen wrote a biography called "Man o' War: Thoroughbred Legends" from Eclipse Press. In 2006, Dorothy Ours wrote a new, extensively sourced biography titled "Man o' War: A Legend Like Lightning". Man o' War is also featured in several books on Thoroughbred breeding, including Avalyn Hunter's "American Classic Pedigrees (1914–2002)". In 1925, Man o' War was seen in the
