In addition to temple shrines to Sobek at Philae and Kom Ombo, tombs with mummified crocodiles were found in abundance near the Nile Delta at Tebtunis, in the Fayum province. These mummies, dating from Ptolemaic times, were wrapped in cartonnage, or a kind of papier mache made from old papyrus documents. Large collections of these papyri with demotic, Greek, and Latin inscriptions have been retrieved and are archived in the Hearst Collection at the University of California at Berkeley.
