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;

Instead, Man o' War made his three-year-old debut in the Preakness Stakes where he defeated Upset by lengths. Man o' War later won the Belmont Stakes by 20 lengths while setting a world record. Throughout the summer and fall, he continued to dominate his fellow three-year-olds, setting multiple records while conceding large amounts of weight to his rivals. The only time he faced older horses was in the final race of his career
