A little confusion here. According to a Yahoo News article there have been several significant discoveries in Saqqara of 19th Dynasty and Late Period coffins.
The Yahoo article goes on to mention that Ahmed Said, of Cairo University, reported that statues of the deceased were also found, suggesting some fairly substantial burials, though the State Information Service makes no mention of the statues, though does report the discovery of “colored vessels for intestines” and a box. The SIS also mentions that the discoveries took place near Unas’ causeway.
