On April 15, the Smithsonian's National Museum of Natural History is welcoming the newest member of our family...a T. rex! We are so excited we want to sing and dance! We've got the song covered: Famed Alaskan artist and musician, Ray Troll, and his band, "The Ratfish Wranglers," recorded "National Rex," an original song about the T. rex's arrival. But we don't yet have the right dance we are asking for your help. Send us a 30 second video of you (and your family or friends) demonstrating your own original "Rex Two-Step" — we will review the submitted videos and post our favorite dinosaur dances on Facebook and Twitter!

The full version of the song "National Rex" is available on iTunes:
