A quarry containing fossil bison and associated artifacts was discovered on the High Plains of northwest Texas in 1944 and excavated in 1945. The bone bed, ranging in thickness from a few inches to I ½ feet, is in a former stream channel at the base of valley fill. At the top of the bone bed the bones are more or less broken while at lower levels and at the bottom the bones are usually complete and often in articulation. Whole skeletons are preserved but are difficult or impossible to separate from associated skeletons. Excavation of 62 running feet (about 500 square feet) of the bone bed yielded parts of skeletons of 100 bison (estimated), together with 26 artifacts. The associated projectile points bear some resemblance to Folsom and Yuma types but are distinctive from both and have been described as Plainview points. The bison is notably larger than the largest individuals of the modern species and is referred to Bison taylori. The only other vertebrate fossil found in the bone bed is a wolf, but near-by localities in the .same horizon have yielded Parelephas columbi [Columbian mammoth] and Equus sp. [North American horse]. Fresh-water in vertebrates of several species are abundant in the bison bone bed and in the same horizon at other exposures in the vicinity.

Paperback. Condition: Very Good condition. NOT a library discard (illustrator). Advance Copy. The Journal of Geology, 1917. This is the original 1917 edition -- NOT print on demand edition or modern reprint. Very Good condition (light cover wear). NOT a library discard. Pages are clean and unmarked. PREPRINTED for private circulation (i. e. Advance Copy) from The Journal of Geology, Vol. XXV, No.1, January-February, 1917. According to an notice at the start, this was issued in advance of the regular Journal "so this important assemblage of data might be in the hands of those specially interested before the holiday meetings of the scientific societies." Bound in the original light brown wraps, printed in black. This is a Presentation Copy to Dr. Arthur L. Day, "Compliments of R. T. C." [i.e. Rollin T. Chamberlin]. Dr. Day was director of the Geo-Physical Laboratory of the Carnegie Institution. It later was acquired by Robert B. Sosman and bears his small ink stamp. A geophysicist and physical chemist, Robert Browning Sosman authored THE PHASES OF SILICA (1965, New Brunswick: Rutgers University Press). Sosman received his Ph.D. from the Massachusetts Institute of Technology in 1907, at the age of 26. By 1908 he had joined the Geo-Physical Laboratory of the Carnegie Institution. Dr. Sosman worked at the Geo-Physical Laboratory for 20 years, serving 8 years as Assistant Director. During World War I, his contributions were instrumental in establishing America's capacity for manufacturing optical glass. In 1928 he left to join the United States Steel Corporation as Assistant Director of Research. Following his retirement from U.S. Steel in 1947, he became visiting professor of Ceramics at Rutgers University. Dr. Sosman was a past president of the American Ceramic Society. In his honor, the Society established The Robert B. Sosman Award, "the highest recognition of scientific accomplishment given by the Basic Science Division. in recognition of outstanding achievement in basic science of an area that results in a significant impact to the field of ceramics.".
