It's possible that lovestruck dinosaurs did bird-like dances to woo their sweethearts. Paleontologists presented evidence of these groovy moves in a study published Thursday in Scientific Reports. They've found four separate sites in Colorado with long fossilized grooves in the Earth that they believe could have been formed by lusty dinosaurs with fancy feet.
"These are the first sites with evidence of dinosaur mating display rituals ever discovered, and the first physical evidence of courtship behavior," study co-author Martin Lockley of the University of Colorado at Denver said in a statement. "These huge scrape displays fill in a missing gap in our understanding of dinosaur behavior."
