Shannon Lee Dawdy, assistant professor of anthropology at the University of Chicago, shows off some of the relics found during an archeological dig behind St. Louis Cathedral in the French Quarter, New Orleans, Tuesday, July 1, 2008.

The Mesopotamian collection at the University of Chicago's Oriental Institute Museum contains numerous examples of cylinder seals seen Tuesday, April 8, 2008. The seals were rolled over wet clay or mud to seal doorways or containers, or to mark tablets. They are part of a new exhibit at the museum, "Catastrophe! The Destruction and Looting of Iraq's Past," detailing the destruction of Iraq's cultural heritage since the start of the war in 2003. Cylinder seals are popular with looters because they are valuable and easy to hide.

An illustration released by the University of Chicago shows the head of a dinosaur named Eocarcharia dinops, or "fierce-eyed dawn shark," for its razor-sharp teeth and bony brow. It was one of two massive meat-eating dinosaurs discovered in Africa by University of Chicago paleontologists in 2000. Eocarcharia's brow was so pronounced that paleontologist Paul Sereno thinks it was used for head-butting rivals to win over potential mates. Both were about 25 feet long and stood 7 feet high at the hip.

An illustration by Project Exploration released by the University of Chicago shows the head of a dinosaur named Kryptops palaios, or "old hidden face," because of a horny covering over its face. It was one of two massive meat-eating dinosaurs discovered in Africa by University of Chicago paleontologists in 2000. Kryptops had a short snout with teeth better for gnawing, leading the scientists to believe he was more of a scavenger. Both were about 25 feet long and stood 7 feet high at the hip.
