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 under heavy restraint and often conceded his rivals large amounts of weight. He retired as the then-leading money-earner in American history. Developing this talent was not easy for trainer Louis Feustel due to Man o' War's occasionally wild temperament. In his early days, Man o' War would routinely dump his exercise riders, once getting free for over 15 minutes after a morning workout. "He fought like a tiger," Riddle later recalled. "He screamed with rage and fought us so hard that it took several days before he could be handled with safety." Feustel brought the colt along slowly and gradually
