In 1913 James Gidley, assistant curator of fossil mammals, Smithsonian Institution, published the paper: A Recently Mounted Zeuglodon Skeleton in the United States National Museum in which he described the first correctly assembled mount of the skeleton of Basilosaurus cetoides, an early whale that was 55 feet long. The skeletal mount was prepared from a composite of two partial skeletons and at the time of publication of his work, was the only one of its kind on exhibition in any American museum.
