The Tucson artifacts, sometimes called the Tucson Lead Crosses, Tucson Crosses, Silverbell Road artifacts or Silverbell artifacts were a controversial archaeological find made in 1924 by Charles E. Manier and his family while out on a Sunday drive to Picture Rocks, Arizona, seven miles north of Tucson. It comprised thirty-one lead objects consisting of crosses, swords, and religious/ceremonial paraphernalia, most of which contained Hebrew or Latin engraved inscriptions, pictures of temples, leaders' portraits, angels, and even what appears to be a diplodocus dinosaur. The name "Calalus" was given to the "terra incognita" (unknown land) based on one of the inscriptions written in Latin. These date to 790 to 900 AD according to the Roman numerals on the artifacts themselves (including the A.D.), but the site contains no other artifacts, no pottery sherds, no broken glass, no human or animal remains, and no sign of hearths or housing. More recent analysis has determined them to be a hoax.
