Dinosaur Man, Chuck Ciampaglio, touches his jaw to show a gathering of youngsters at the Dwyer Library in Celina where the large dinosaur bone he is holding would be in the Tyrannosaurus Rex. When he is not discussing large dinosaur bones and what we know about them, Ciampaglio is an associate professor of geology at Wright State University, Lake Campus. The dinosaur talk was presented at the main library for kids age six and up on Thursday.
