Iowa State gave college football fans one of the season’s best halftime shows Saturday.

At home against No. 6 West Virginia, the Cyclones’ marching band took the field and was followed by dozens of people in inflatable tyrannosaurus rex costumes. But these dinosaurs did more than just look like goofy lawn ornaments or haphazardly move around. They (mostly) danced in choreographed unison while the band played the theme song to Jurassic Park.

While they weren’t totally coordinated, they most certainly were entertaining, and it’s actually pretty funny to see them not quite perfectly timed.

According to the Ames Police Department — which was jokingly a bit alarmed at the sight of all these dinosaurs overtaking the field — the band celebrated other famous theme songs from classic movies like Star Wars, Jaws and E.T.

Um, what is happening here with the 30 dinosaurs on the field? #jurassicband #Cyclones pic.twitter.com/s04Z6rJB2z — Ames Police (@AmesPolice) October 14, 2018

That’s some stellar effort all around and a delightful complementing show to a thrilling Big 12 game.

But this wasn’t the only entertaining halftime show Saturday. Ohio State’s marching band filed into formation on the field to imitate the Backpack Kid’s viral dance.
