Visit the John G. White Reading Room of the Special Collections Department to see the baby mammoth jaw first displayed at the Cleveland Public Library in 1909. On May 9th, 1909 The Cleveland Plain Dealer published an article entitled In the Days of the Cleveland Elephant; it described a baby mammoth jaw that was discovered in March of that year. The jaw was found during the construction of a sewer at E. 40th and Euclid Avenue adjacent to the residence of Mr. Sylvester Everett, whose palatial home was built by architect Charles Schweinfurth. This area was at that time considered to be one of the most prestigious streets in the nation.
