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 Raise A Native, who is an almost "omnipresent name in American pedigrees". Some modern breeders design matings to concentrate the influence of Man o' War through deep inbreeding. For example, he appears at least 22 times in the bloodline of American Pharoah, the 2015 Triple Crown winner. Man o' War was retired from stud in 1943 after suffering a heart attack. He died on November 1, 1947 at age 30 of another apparent heart attack, a short time after Harbut died. His funeral was broadcast live on NBC Radio.
