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 proudly proclaim his charge's many accomplishments. Man o' War and Harbut were featured together on the cover of the "Saturday Evening Post" in 1941. This photograph inspired a popular collectors' plate, "Forever Friends", by equine artist Fred Stone. Man o' War was the leading sire in North America of 1926 and was runner-up in 1928, 1929 and 1937. The Jockey Club credits him with 62 stakes winners from 381 named foals. Riddle restricted Man o' War's book to about 25 mares a year, most of which were owned by him or his friends and family. Though many breeding experts believe
