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 War Admiral, the 1937 Triple Crown winner and the second official Horse of the Year. Another of his offspring, Hard Tack, sired Seabiscuit, who was Horse of the Year in 1938. Man o' War's most successful sons at stud were War Admiral and War Relic, and War Relic's branch of the male line survives today. Tiznow, Tourist, Da' Tara, In Reality, Desert Vixen, Honour and Glory, Bal a Bali, Skywalker and Bertrando are all sire-line descendants of Man o' War. Man o' War's influence in modern pedigrees is magnified by the success of his daughters as broodmares. Although Man o'
