Abstract

There was recently added to the paleontological collections at the University several fragments of shells of eggs of the dinosaur Protoceratops andrewsi. They come from the Dja-doch-ta beds of Cretaceous age at Shabarahk Usu, Outer Mongolia, China. The bits of eggshells and a piece of the skull with teeth in place and a part of the frill were collected and presented by Dr. Ralph W. Chaney a member of the Third Asiatic Expedition. (See NATURAL HISTORY, volume xxv, Nov.-Dec. number, 1925, pages 622, 623). The eggshell fragments are over one millimeter thick, are smooth on the inside and are marked by a maze of grooves and ridges on the outside. The pieces are from one to three centimeters across and judging from their curvature the entire eggs were several inches long. They occur in a brick-red friable sandstone, blocks of which were packed for shipment to America in camel's hair, the only available packing in that part of the desert.
