Quitaque Creek
Basic information
Sample name: Quitaque Creek
Reference: W. W. Dalquest. 1964. A new Pleistocene local fauna from Motley County, Texas. Transactions of the Kansas Academy of Science 67(3):499-505 [ER 4078]
Geography
Country: United States
State: Texas
County: Motley
Coordinate: 34.23° N, -100.71° W
Coordinate basis: estimated from map
Scale: outcrop
Time interval: Late Pleistocene
Ma: 0.0314
Age basis: radiocarbon (uncalibrated)
Geography comments: "in the bed of a small arroyo tributary to Quitaque Creek, in the northeastern corner of Motley County"
"The Pleistocene terrace from which the fauna were collected is on the north side of Quitaque Creek, beginning approximately one-half mile east of (downstream from) the crossing of State Farm Market Road 599, and extending for about one-quarter of a mile. The sediments of the terrace are apparently continuous and lie at one level above the present stream bed"
said to be "early Wisconsin" in age, and freshwater mussel shells were dated by radiocarbon at 31,400 ± 5600 and 31,400 ± 3200 ybp

Environment
Lithology: claystone
Habitat comments: "sands and gravels, irregularly bedded and often cross-bedded, and gray to brownish-gray clay beds" and the fossils are mostly from the clay
"the present deposits are terrace sediments, resulting from the filling of an older, broader valley... Presumably the clays were deposited in ponds or oxbow lakes on the old floodplain"

Methods
Life forms: bats,carnivores,rodents,ungulates,birds
Sampling methods: screenwash
Sample size: 29 specimens
Years: 1958
Sampling comments: the site was discovered by Gene Wilson in 1958
"On subsequent visits to the area additional vertebrate fossils were found, and a ton of gray clay matrix was washed and sorted... all of the large mammal bones were taken in three small areas fifty yards apart" and the screened sampled is not said to be from elsewhere
molluscs including the mussels were collected and were to be reported later by D. Allen and E. Cheatum
"unidentified fishes, catfish fin spines, broken frog bones and snake vertebrae" are also present and "One broken bird bone was identified by Dr. Pierce Brodkorb, of the University of Florida, as belonging to a small finch" (= Fringillidae indet.)
