There was a dinosaur stampede in downtown Nashville, and it was a sight to see!

People dressed up as T-Rexes and went for a jog together.

The organizer said this idea started as a joke when he posted it on Facebook.

He said he got a lot of positive feedback and strangers willing to join in.

They started at the Pedestrian Bridge near Shelby Avenue and finished near Acme Feed and Seed on Broadway

"It could be a little cooler,” Jonathan James said. “I did a test run earlier when it was this hot and I came out very drenched, so it's going to be a sweaty stampede."

So this is happening. A bunch of Dinosaurs are about to take over downtown. pic.twitter.com/5jX52Qn95g — Brandon Marshall (@NC5_BMarshall) October 29, 2016

For anyone wondering, they said they bought their costumes on Amazon.
