In the Division of Vertebrate Paleontology the outstanding accession of the year resulted from field work by associate curator Peter P. Vaughn, during the spring of 1958. Excellent materials representing a number of genera of fish, amphibians, and reptiles were obtained from the Clyde and Arroyo formations of Baylor County, Tex. Included in Dr. Vaughn's field collection were also remains of small, primitive vertebrates from a Permian [[inserted]] fissure filling in the Arbuckle limestone at Richard's Spur, Okla. Vaughn arranged the gift from Mr. D. E. Jones of Delta, Colo., of the largest dinosaur bone, 6 feet, 10 inches long, known from this country, a humerus of the Jurassic genus [underlined] Brachiosaurus.

Two accessions of fossil fish received in exchanges furnished exhibition material: One is a specimen of the Triassic coelocanth [underlined] Diplurus newarki, together with its life restoration to scale, received from Princeton University; the other includes 81 specimens of fossil sharks and ray-finned fishes from two marine Upper Cretaceous formations in Lebanon from the School of Engineering, American University of Beirut, through Dr. Harry M. Smith.

Two gifts added importantly to the Museum's unusual collection of fossil fish from Cuba, significant as the only record of the late Jurassic marine piscine fauna from the Western Hemisphere: (1) 7 specimens including holostean and halecostome genera from a new locality in Pinar del Rio Province, by the Cuba California Oil Company through Dr. A. A. Meyerhoff, and (2) 27 specimens of comparable forms collected by Sr. Juan Gallardo from various localities in Pinar del Rio Province, purchased by the Walcott fund.
