Dinosaurs Gathered to Perform Mating Dances With Kicks and Spins at This Site in Colorado—and You Can Go See It for Yourself

DENVER COUNTY, COLORADO, JUL 14 – Researchers uncovered physical evidence of dinosaur courtship behavior at Dinosaur Ridge, identifying the largest known lek where theropod males performed mating displays, a rare find worldwide.

  • A research team discovered evidence of dinosaur mating dances from 100 million years ago at Dinosaur Ridge near Denver, Colorado.
  • This finding follows prior observations of peculiar markings on a hillside and builds on knowledge of dinosaur behavior in the region’s late Cretaceous period.
  • The site, accessible to the public, displays patterns of foot scraping by male dinosaurs likely used to assert territory and attract mates.
  • Researchers identify this site as the biggest known area where dinosaurs gathered for courtship, highlighted by two nearly vertical scrape marks made by alternating foot movements during their display behavior.
  • The discovery suggests complex social and courtship behaviors in dinosaurs similar to modern birds, offering ongoing scientific insights at a site nearly 100 years known for fossils.
