Attached caption: More than a hundred million years of the earth's history written in fossil shells imbedded in eight tons of rock is being deciphered by Smithsonian paleontologists. This is the Permian Geological epoch, extending from about 212,000,000 to 175,00,000 [sic] years ago. It was one of the great transition periods of earthly time when the palent's [sic] curst [sic] was becoming fixed into something approaching its present contour and back-boned animals, including the possible ancestors of mammals had conquered the land. Predominant fossils are those of shelled sea creatures whose remains became imbedded in offshore sea-bottom ooze. Most of them were small. Their fossils are like cryptic letters stamped in rock. Photo shows Dr. G. A. Cooper at work with some of the rock in a special lab which has been set up for the work. A total of 10 tons of accumulated rock is being etched out and classified.
