‘Dinosaur Giants’ A display of teeth, claws and bones unearthed by University paleontologist Paul Sereno, Professor in Organismal Biology & Anatomy, will greet visitors of “Dinosaur Giants,” a free exhibit at Navy Pier’s Crystal Gardens, through March 19. Pictured here are two specimens of Sereno’s latest discovery, Jobaria tiguidensis. Sereno or members of his team will be on hand to answer questions about the exhibit from 10 a.m. to 6 p.m. Saturdays and Sundays throughout the exhibition schedule. “Dinosaur Giants” was created by Project Exploration, a not-for-profit organization geared toward offering children of all ages hands-on natural science experiences.
