The excavations were sponsored by the Graeco-Roman branch and thus were concerned with recovering papyri from the Graeco-Roman period rather than objects or material from different time periods.
The late Ptolemaic burials were placed under rock ledges without sarcophagi. Only one of the mummies had papyrus cartonage and some of the tombs contained dogs.
