DINOSAUR BONE COLLECTORS The first recorded dinosaur remains found consisted of a few teeth and bones discovered (1822) in Sussex, England, by an English doctor, Gideon Mantell, who named them Iguanodon ("iguana tooth"). About the same time, other fossil teeth and bones were found near Oxford, England, by Rev. William Buckland. These were named Megalosaurus ("great lizard"). As Americans found exciting new kinds of dinosaurs in the west, two wealthy professors began a rivalry that has come to be known as "The Great Dinosaur Wars." Othniel Marsh of Yale University and Edward Cope of Haverford College both fielded fossil-hunting teams, racing desperately to find new fossil beds to name the next dinosaur. In their hurry to name what appeared to be a large new dinosaur, Marsh's team placed the wrong head on a specimen and gave it the name "Brontosaurus." When it became clear that the head belonged to Camarasaurus and that the body was the same as the Apatosaurus skeleton that had been found earlier, the name Brontosaurus was dropped. Unfortunately, the name continues on in popular usage, as is demonstrated by this 1989 US Postal Service stamp. While the western US continues to be popular ground for paleontologists, thousands of dinosaur specimens have since been discovered all over the world, including Antarctica."
