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.…

Softcover. Zustand: Very Good. Book is clean and tight. Has small tear on front and back cover and I made a tear on last page of index when I was trying to separate pages with cold hands during Winter Storm Fern. It is in the 30s here in Corpus and I am in the garage listing books with no heater. Tear at top of spine and bumped corners. Surface pull on front cover. Husband says best article is the one by Bullard on Geology of Montague County, but there is stuff on oil fields in North-Central Texas, Sour Lake and Big Lake also.
