2. Natural Museum of Los Angeles County Saber-Toothed Tiger

Currently, the Natural Museum of Los Angeles County hosts a well-regarded dinosaur collection, but it will soon expand its exhibit when its Dinosaur Hall opens this coming summer. According to a Business Wire article, the new Hall will make the Los Angeles museum a world leader in dinosaur exhibits, featuring over 300 fossils and 20 full-body specimens. The museum endeavors to make the public more aware of the process of excavation and preparation, as well as to shed light on how dinosaurs lived, by way of interactive media. Especially notable is its T-Rex adult, Thomas, one of the most complete specimens on the planet.
3. Cincinnati Museum Center A View From The Front

4. Utah Museum of Natural History Dinosaur Exhibit

UMNH has a wonderfully diverse range of dinosaur specimens, mostly from the Late Jurassic period. Many of its fossils were found in the Cleveland Lloyd Dinosaur Quarry in Emery County, Utah, which possesses the densest concentration of Jurassic fossils in the world. The latest additions to its stunning collection are two new species of iguanadonts—a Hippodraco and an Iguanacolossus. Iguanadonts are large, beaked, herbivorous dinosaurs from the Cretaceous period. The skull of the Hippodraco will be on display at UMNH early next year.
