Theropod Dinosaurs Gathered to Court and Nest in Ancient Colorado

Fast Summary

• Researchers have identified a theropod dinosaur lekking site at Dinosaur Ridge in Colorado, dating back approximately 100 million years.
• Fossilized tracks known as Ostendichnus suggest that male theropods gathered to perform ritualistic courtship dances aimed at attracting mates and building nests.
• 25 new fossilized tracks were discovered using drone imaging, distributed across two stratigraphic surfaces. These include circular indentations, likely for nesting, and scratches linked to courtship displays.
• Study findings indicate that the high-density traces demonstrate organized group behaviour during multiple seasons over time.
• The theropods responsible for these tracks were possibly small omnivorous or plant-eating dinosaurs resembling modern cassowaries or emus in size and appearance.

Indian Opinion Analysis
The discovery of ancient lekking behavior among dinosaurs sheds fascinating light on prehistoric social dynamics and mating rituals of theropod species. For India,this study indirectly emphasizes the importance of preserving fossil sites like those in Gujarat’s Kutch Basin or Maharashtra’s Lonar Crater region,which hold clues to India’s paleontological history spanning millions of years. Knowledge from such findings can enhance global scientific understanding while fostering educational tourism opportunities rooted in India’s natural history heritage.
