Looking for dinosaursThe study of dinosaurs first began when someone uncovered a dinosaur jaw bone in Holland in 1770．Soon other dinosaur bones were discovered in England and scientists began to put the bones together to make models of dinosaurs．In 1855, Edward Drinker cope and Othniel Charles marsh discovered dinosaur teeth and bones in the United States and began to construct their own dinosaur models．Although they made some mistakes(such as putting the head on the wrong end of one of their dinosaur models), their work added greatly to our knowledge of dinosaurs．By the 1890s, these two men had discovered 130 new types of dinosaurs using the bones they found in Colorado, Montana, and Wyoming．
Today there are thousands of places where dinosaur bones may be found．However, there are not enough scientists to go to all these places．The Denver Museum of Natural History is helping solve this problem by training dinosaur hunters．They offer eight courses on how to find and take care of dinosaur bones．They have already graduated over 100 “dinosaur hunters”
Number these events in the correct order
□ Dinosaur bones were first discovered in the Unite States．
□ The Denver Museum of Natural History began training dinosaur hunters．
□ Dinosaur bones were discovered in Holland．
□ 130 new types of dinosaurs were discovered by Cope and Marsh．
