Roy chapman andrews's career.

From 1909 to 19 10, he went to east indies with the albatross, where he collected snakes, lizards and other animals and observed marine mammals. 19 13 years, he went to the north pole with the sailing ship adventure. They originally wanted to get a bowhead whale specimen for the American Museum of Natural History. Although he failed to achieve his goal in the end, he succeeded in photographing some seals he had never seen before. He married Yvette Borup. From 19 16 to 19 17, the two of them led an Asian zoological expedition from a museum to China, and visited southwest Yunnan and other places in China. He later recorded this experience in the book Campus and Paths in China. 1920, roy chapman andrews went to China again, and took the Dodge bus from Beijing to visit western Mongolia. 1922, the expedition team found the giant rhinoceros fossil, which was returned to the museum in the same year 12+09. During 1920s, he had hoped to find some traces of human origin in Mongolia. Although I didn't get what I wanted, I still found precious dinosaur bones. During his four expeditions in Gobi from 1922 to 1925, he discovered protoceratops, a nest of protoceratops eggs (which were later proved to be eggs of egg-stealing dragons), painted dragons, sauropods, egg-stealing dragons and raptors. These are all unknown before. 1923 On July 3, the expedition discovered dinosaur eggs for the first time in history. At first, people thought that they belonged to protoceratops and were eggs laid by Ceratosaurus, but in the end, it was proved in 1995 that these eggs actually belonged to the egg stealing dragon of theropod. Walter W. Granger also found a Cretaceous skull. 1925 the museum sent back a letter saying that this skull belongs to a rare mammal. The exploration from 1926 to 1927 has come to an end. 1928 The discovery of the expedition was seized by the China authorities in Zhangjiakou, which led American diplomats in China to negotiate with the China authorities, and finally these collected antiques were returned. The expedition of 1929 was finally cancelled. 1930, he found some mastodon fossils on his last trip. Photographer James B. shackelford took many photos of Anders during the expedition. Six years after roy chapman andrews's exploration, the American Museum of Natural History returned to Mongolia at the invitation of the Mongolian government to continue its exploration. After that, roy chapman andrews returned to the United States and divorced his wife. 1927, American scouts awarded him the title of "honorary scout". This newly established title was awarded to "an American citizen whose achievements in outdoor activities, outdoor adventures and other fields can satisfy children's imagination".

1908, roy chapman andrews joined the new york Explorers Club. He is the chairman of the club from 193 1 to 1934. 1934 roy chapman andrews became the curator of American Museum of Natural History. 1942 after retirement, he lived in Carmel, California. There he wrote down his life experience and died in 1960. After his death, he was buried at Oakwood Cemetery in his hometown of baloyi.
