Although the Smithsonian’s National Museum of Natural History’s dinosaur and fossil hall is still undergoing renovations—it’s scheduled to reopen in 2019— dinosaur nerds don’t have to wait forever to get their fix. Tomorrow, the Museum will open its latest exhibition, which features new skeletons of a Triceratops and Tyrannosaurus rex.

“The Last American Dinosaurs: Discovering a Lost World,” according to the Museum, “tells the story of non-avian dinosaurs’ final years in western North America through an extraordinary diversity of animals and plants discovered in the fossil-rich layers of the Hell Creek Formation in North Dakota, South Dakota, and Montana.”

In the 5,200-square-foot exhibition, which will open on the second floor of the museum, there will be two near-complete skeletons, one of “Hatcher,” a giant Triceratops, and an almost-14-foot-tall cast of the T. Rex skeleton named “Stan.” Additionally, the exhibition will feature skulls of and adult Edmontosaurus, an infant Triceratops, fossil displays, murals of ancient environments, video and interactive displays, and artist renderings of what the currently in-progress dino hall will look like when it’s done.

The exhibition will be up until the new dinosaur opens up. Also worth noting: the new exhibition opens just a day before the Jurassic World trailer premieres. It’s a good week to be a dinosaur nerd.
