It's a holiday dedicated to the prehistoric creatures that once roamed the earth. It’s National Dinosaur Day!

News 12's Jenn Seelig is at the Center for Science in Rockville Centre getting a sneak peek at the new additions just in time for its big "Dino Weekend.”

The center is welcoming two new dinosaur additions to the center to celebrate, including the Dilophosaurus.

The center has the largest collection of animatronic dinosaurs in the state of New York.
