. Annual report for the year ended June 30 .... United States National Museum. EXHIBITS 13 The dominance of tlie dinosaurs in the terrestrial fauna of the age of reptiles is illustrated by displays representing all major groups of dinosaurs, in which the examples range in size from one ^Yhose arm bone was 6 feet long to a tiny beast with a thigh bone smaller than that of a chicken. A number of these specimens are unique, such as the skeleton of Thescelosawms—a small, agile, plant-eating dinosaur that lived near the end of the age of reptiles. Special exhibits show methods of classifying the dinosaurs and the various ways in which they adapted to their environment. The dinosaurs in this museum are of historic as well as scientific interest. Many of the specimens were collected during the early United States Geological Survey ex- plorations associated with the opening of the West between 1870 and 1895. Later acquisitions were made by Smithsonian expeditions, and through gifts and exchanges. The material is well known to paleon- tologists the world over. Reptiles that include the ancestry of mammals also are displayed in this hall. These animals apparently were never abundant in the United States, and the exhibited fossils were collected recently in South Africa by an expedition sponsored jointly by the Smithsonian Institution, National Science Foundation, and the Bernard Price In-.
