Prehistoric ‘dancefloor’ could reveal how dinosaurs flirted

Around 100 million years ago, on a tidal flat near what is now the city of Denver in Colorado, US, dinosaurs may have gathered to dance.

According to a new study published in Cretaceous Research, new findings suggest that dozens of mysterious scrape marks preserved in stone at Colorado’s famed Dinosaur Ridge represent one of the largest-known dinosaur mating display arenas – or leks – ever discovered.
