HAYS, Kan. -- Dr. Paul Sereno, a professor at the University of Chicago, a National Geographic explorer-in-residence and SuperCroc discoverer, will speak at Fort Hays State University's Sternberg Museum of Natural History at 7 p.m. Saturday, April 17.

After Sereno and his team of fossil hunters explored the Sahara Desert in Niger in 1997 and again in 2000, they discovered partial skeletons and numerous skulls of 40-foot Sarcosuchus imperator, the largest crocodile that ever walked the earth. The expeditions also yielded 20 tons of other fossils, a National Geographic documentary and the traveling exhibition "The Science of SuperCroc," which is on display at Sternberg Museum until Aug. 5.
