In honor of the T. rex’s arrival, the Smithsonian is encouraging people to get up and dance. They’ve teamed up with Alaskan artist and musician Ray Troll and his band, The Ratfish Wranglers, to create “National Rex,” an original song celebrating the dinosaur’s arrival and they want you to send in a 30 second video dancing to your own original “Rex Two-Step.”

To participate, all you have to do is listen to the song, get inspired, and start moving. Whether your dance involves classical steps or a modern flare, as long as you’re moving and having fun, you could be featured on Twitter (@NMNH) or Facebook! Check out all the rules, and follow along with the hashtag #rexstep!

Here at Let’s Move!, we’re all for getting active, and dancing is a great way to add activity to your daily routine. So why not grab a camera and show the T. rex how you move?

The actual T. rex specimen arrived at the National Museum of Natural History on April 15, and will be the centerpiece of the museum’s new 31,000-square-foot dinosaur and fossil hall, which is slated to open in 2019.
