• "We found the fish-bearing paper shales associated with sandstones in which were sauropod reptiles at Ondai Sair. At the Oshih (Ashile) basin we searched the paper shales this year again for fossils, but found only the remains of a few plants, too badly macerated prior to deposition to be identified. The paper shales of the Oshih basin carry gypsum crystals, which perhaps points to bitter waters in which the fauna of Ondai Sair could not live. The Oshih and Ondai Sair basins are very probably continuous and form one basin. Sauropods and primitive predentates are found in each locality, although perhaps there is a slight difference between the two faunas. At Oshih the paper shales lie far higher in the series, not less than five hundred feet above the chief sauropod beds; but a few large sauropod vertebrae were seen only one hundred feet below a horizon which, on other grounds, we believe is correlated with the paper shales. At Ondai Sair, as I have said, the sauropods are found close to the paper shales and essentially of the same age...Clearly, there is a great unconformity beneath the Oshih and Ondai Sair and, so far as we know, these basins, which carry the paper shales, date the beginning of the basin or gobi sedimentation; that is, the beginning of deposition of shallow masses of continental sediments-alluvial fans, flood-plains, deltas, playa lake deposits and, locally, deposits in shallow but more permanent lakes. These deposits are but little disturbed and it is in them that all the vertebrate fossils are found."
