Giant Eggs of Dinosaur Found in Mongolia
Peking…..Above is shown Roy Chapman Andrews, zoologist and hunter, who was in charge of The Third Asiatic Expedition of the American Museum of Natural History, which has just returned here after five months on the Mongolian Plains. The specimens brought back by the expedition are declared to be the most interesting in recent years. Giant eggs, five or six inches long and proven to be those of dinosaurs of ten million years ago, are among the principal specimens. The prehistoric and colossal reptiles had nests just like ordinary fowl of the present era. The expedition is bringing back also about nine tons of fossils, comprising 72 skulls and twelve complete skeletons of these “terrible lizards” as the two Greek words forming the term “dinosaur” describe them.
