Teeth, talons and feathers: COSI dinosaur exhibit set to open (Video)

The dinosaur gallery features a full-size cast skeleton of a Tyrannosaurus Rex; a 60-foot metal model of an Apatosaurus; a massive femur – one of two in existence – of a gargantuan Titanosaurus; exhibits on dinosaur behavior, extinction, nests, eggs and babies; a diorama of a 130-million-year-old forest in what is now China; a look at feathered dinosaurs; bones, beaks and claws; and how some learned to fly.
