Gail of Scribal Terror has a neat rundown of the 7 great discoveries in Biblical archaeology. Of course, the Dead Sea Scroll is there, but the rest are largely unknown to the general public. For example:
An ossuary is a stone bone box, used for secondary burials. Initially the body is laid to rest in a burial niche. After decomposition, the bones were collected and placed in an ossuary, making the burial niche available for a subsequent burial. Tombs belonged to families, so subsequent burials were normal. Two of a dozen ossuaries in [a] tomb [discovered in 1990] contained a form of the name Qafa', or Caiaphas. Several of the ossuaries were decorated with traditional carved rosettes, zig-zag patterns, and other designs. The most intricately carved ossuary was decorated with two circles each containing five rosettes, and twice carved into an undecorated side appears the name, "Yehosef bar Qafa'" (Joseph son of Caiaphas). The ossuary contained the remains of six people: two infants, a child aged two to five, a boy aged 13 to 18, an adult female and a man about 60 years old. The latter are believed to be the bones of Caiaphas, before whom Jesus was brought for questioning.
