WASHINGTON (WNEW) — Just in time for one of the busiest periods of the year, the Smithsonian is putting two really big attractions back on display at the Museum of Natural History.

“Stan” the Tyrannosaurus Rex and “Hatcher” the Triceratops have long been a part of the museum’s fossil hall, but it’s under renovation until 2019. Now they have a new home in a display that examines the final days of dinosaurs in America, 66 million years ago.

With exposed plywood all around, exhibit developer Sally Love-Connell says this not a “polished” display.

“We’re trying to recreate the environment that these last dinosaurs lived in,” Love-Connell says.

Instead, it’s meant to recreate how scientists do their work on-site.

“Show people a little bit of behind the scenes… this is how we figure things out,” Love-Connell says.

The 5,200-square-foot exhibition opens Nov. 25 on the second floor of the museum. The museum says it 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.
