The Smithsonian Institution’s Division of Mammals (http://vertebrates.si.edu/mammals/) houses many suids in its scientific collections.http://vertebrates.si.edu/mammals/ This specimen, USNM 144421 (http://collections.mnh.si.edu/search/mammals/?irn=7251992), is a male wild boar (Sus scrofa) from Indonesia. This individual was collected by William Abbott in 1907 near the Rhio Archipelago off of the island of Sumatra.http://collections.mnh.si.edu/search/mammals/?irn=7251992 This is a CT scan of the right, fourth metatarsal of USNM 144421. These three-dimensional scans are made publicly available through the generous support of the Smithsonian 2.0 Fund, provided from the annual gifts of the Smithsonian National Board to the Secretary to use at his discretion (http://smithsonian20.si.edu/fund.html), and the Smithsonian Collections Care and Preservation Fund.http://smithsonian20.si.edu/fund.html The main goal of this joint initiative between the Human Origins Program and the Division of Mammals is to make the NMNH's scientific collections available in 3D for education and research.
