摘要：

The mammals of the Carrol Creek local fauna, radiocarbon dated at 32,400 +/- 560 YBP, were found in a late Pleistocene (Middle Wisconsin, Rancholabrean Land Mammal Age) deposit in Donley Co., Texas. Thirteen of 17 taxa were at least tentatively identified to species. Neofiber leonardi, Synaptomys australis, Mammuthus columbi, and Equus sp. are extinct. Sorex arcticus and Microtus pennsylvanicus now occur far from the fossil site. The remaining taxa are typical prairie forms living near the fossil site today. Carrol Creek is the southernmost record of S. arcticus, and N. leonardi is herein documented during the latest Pleistocene. The association of S. arcticus, N. leonardi, and S. australis are recorded together for the first time and suggest a mesic environment and an equable climate.
