The Quarry Exhibit Hall allows visitors to view the wall of approximately 1,500 dinosaur bones in a refurbished, comfortable space. Here, you can gaze upon the remains of numerous different species of dinosaurs from the Late Jurassic period, including Allosaurus, Apatosaurus, Camarasaurus, Diplodocus, and Stegosaurus, along with several others. There are even several places where you can touch real 150 million year old dinosaur fossils! Rangers are available to answer questions, help kids complete their Junior Ranger booklets, and occasionally provide talks on different topics related to the quarry or dinosaurs during the summer.
