Abstract
A Brief note in Science in the spring of 1943 reported the find of an association of human burials and artifacts with the remains of Camelops, Equus, and Bison, near Tranquillity, Fresno County, California. The present paper is a more detailed description of the cultural remains and a fuller report of the writer's findings at the site prior to 1944. Excavations in that year by the University Museum, University of Pennsylvania, are mentioned below. They will be described in a forthcoming paper by Lloyd and Satterthwaite, to include a critical examination of the evidence for and against the contemporaneity of the human and extinct mammal remains.
