Dinosaurs/Hall of Paleobiology
The Hall of Dinosaurs has fossilized skeletons and cast models, including Tyrannosaurus Rex facing off with Triceratops. In May 2012, billionaire David H. Koch donated $35 million toward the cost of a $45 million upgrade to the 30-year-old, 25,000 square feet dinosaur hall. The hall is anticipated to close in the spring of 2014 and reopen in 2019.
