Visitors walk through the Great Hall at Fernbank Museum of Natural History, May 23, 2014, in Atlanta, Georgia. The large dinosaur to the left is Argentinosaurus, a plant-eating dinosaur that weighed more than 100 tons and was 123 feet long. The dinosaur to the right is Gigantosaurus, which weighed eight to 10 tons and was the largest meat-eating dinosaur. Fernbank opened in 1992 and is known for its massive dinosaur exhibitions. The museum also has an IMAX theater and holds popular public events like monthly salsa dance nights and the weekly "Martinis & IMAX" program. (Photo by Carmen K. Sisson/Cloudybright)
