Chesapecten jeffersonius is the state fossil of the State of Virginia in the United States. It is the fossilized form of an extinct scallop, which lived in the early Pliocene epoch between four and five million years ago on Virginia's coastal plain. In 1687, Martin Lister published a drawing of C. jeffersonius, making it the first North American fossil to be illustrated in scientific literature.
The Jeffersonian Apartments is a large apartment building at 9000 East Jefferson Avenue, on the near-east side of Detroit, Michigan. Built in 1965, primarily of glass and steel in the international architecture style, it is one of Detroit's tallest residential buildings -- standing 30 stories with 412 residential units.
The Jeffersonian was an all-coach passenger train operated by the Pennsylvania Railroad between New York City, Washington, D.C., and St. Louis. Inaugurated in 1941, the services equaled that of the Trail Blazer , and it was equipped with modernized coaches, twin diners, and observation cars. In 1948, it was re-equipped with new lightweight cars and given a unique car, a recreation car, complete with a movie theater, game tables, and a playpen for kids. In 1956, the Jeffersonian was discontinued, and its cars went to other trains. Its coaches went to the Indianapolis Limited and Spirit of St. Louis (breaking that train's all-Pullman status). In addition, the General started carrying through cars to Washington, D.C. Its recreation car went to the Penn Texas .
