In the Peabody Museum at Yale University is the skeleton of an extinct species of ground sloth, Nototherium, that was recovered from a cave in New Mexico where it was buried and preserved in bat guano. The preserva- tion was so complete that it was possible to determine by the stomach con- tents that it died in the spring of the year, and that the vegetation of Pleis- tocene times was practically like that of today. 3.
