About the Oklahoma Museum of Natural History:
Two ancient battles punctuate the Hall of Ancient Life at the Oklahoma Museum of Natural History. The centerpiece of this exhibit is a fight to the death between Saurophaganax and Apatosaurus (both specimens of which were unearthed in the Oklahoma panhandle), while nearby, a pack of Deinonychus surround a much bigger Tenontosaurus. This hall also features numerous other fossils, including one of the most complete Pentaceratops skeletons in the world (the skull of which is verified as "World’s Largest" by the Guinness Book of World Records).
The dinosaur and prehistoric life galleries at the Oklahoma Museum of Natural History are arranged chronologically, leading visitors past specimens from the Paleozoic, Mesozoic and Cenozoic Eras (this last part of the hall features a nine-foot-tall woolly mammoth, also dug up in Oklahoma, and a Smilodon, or saber-toothed tiger). One innovative feature here is the Dinovator, an elevator you can take to look that Apatosaurus skull right in its bony eyes!
