The Smithsonian’s National Museum of Natural History will reopen its dinosaur and fossil hall Saturday, June 8. The 31,000-square-foot exhibition will feature an authentic *Tyrannosaurus rex*skeleton alongside more than 700 other fossil specimens, including mammals, reptiles, plants and insects—some never before displayed at the museum. The exhibition tells the story of 3.7 billion years of life on Earth, highlighting the connections among ecosystems, climate, geological forces and evolution and encouraging visitors to understand that the choices they make today will have an impact on the future. “The David H. Koch Hall of Fossils—Deep Time” is named in recognition of a $35 million gift from David H. Koch.

A video trailer for the exhibition, high-resolution photos of the Nation’s *T. rex* and other fossil specimens in their new poses and related press materials are available via the following Dropbox link and password. News-media use of these assets to promote “The David H. Koch Hall of Fossils—Deep Time” is permitted with attribution.

Woolly mammoths (*Mammuthus primigenius*), perhaps the best-known mammals of the ice ages, went extinct due to a combination of shifting climate, changing food sources and a new predator—humans. Even without other factors, rapid changes in climate can drive species toward extinction.

-  “Irish Elk,” *Megaloceros giganteus*
Often called the “Irish Elk,” *Megaloceros giganteus* ranged beyond Ireland and its closest living relative is the fallow deer, not the elk. This giant deer lived across northern Eurasia from Siberia to Ireland, and like other deer, shed its giant antlers every year.

Phytosaurs resemble crocodiles, but they are not closely related. This is a case of convergent evolution: the two groups independently evolved similar features as adaptations to similar lifestyles. This Triassic land-dweller, *Smilosuchus gregorii*, will be on display in “The David H.

Animals began to settle on land once microbes and plants provided food and habitats. The first terrestrial arthropods included eurypterids making brief trips from shallow water to shore. They already had legs but faced challenges breathing and walking in thin, dry air.
