Description
A fossiliferous remnant of a small lacustrine unit was discovered in an arroyo midway between the Santa Catalina Mountains and the San Pedro River, Pinal County, Arizona. Radiocarbon dates provided a range of 27,000 to 12,000 years before present for existence of the impoundment and accumulation of sediments and enclosed fossils. Mammuthus, Mammut, and Equus formed the megafauna. Mollusks and pollen provided additional evidence for a paleoenvironmental reconstruction of the local area as a pond or small natural impoundment for this late Pleistocene locality.
