The museum plans to open its Hall of Paleontology to the public this summer. The hall is the length of a football field and features dozens of different dinosaurs.
Included in the display are some favorites, like the Tyrannosaurus Rex and the Triceratops, and some relatively unknown dinosaurs like a display 7-year-old Hannah Aaronson donated to the museum. It's a replica fossil of an arthropod more than 500 million years old
"We went to Tucson and there was an auction there, so we went to the auction and I bought it," said Hannah Aaronson, who donated the display. "I thought that it may be really cool for other kids to see my thing."
The museum's new Hall of Paleontology opens June 2.
