Archaeologists discovered four coffins containing mummies in the largest burial yet found at Deir el-Banat, an ancient Egyptian necropolis southwest of Cairo.

Three of the coffins were made of wood and a fourth, child-size casket was made of a papyrus-like material. The smallest coffin was also set in the grave at a different angle than the others, as seen in this November 20, 2007 photo.

Experts think the tomb belonged to a family and that the four coffins might have been interred together.

Inside one of the coffins, archaeologists uncovered a mummy wearing a gilded mask, a rare find for a site once thought to have been entirely plundered.
