## An Ancestral Behavior That Continues
A remarkable discovery in Colorado’s Dinosaur Ridge has revealed evidence of a “lek” – an ancient arena where dinosaurs gathered to court, compete, and mate – dating back 100 million years. This finding, reported in Cretaceous Research, provides unprecedented insight into the social behaviors of dinosaurs and demonstrates a striking continuity of courtship rituals across evolutionary time.
The site, a preserved Cretaceous-era beach, contains numerous parallel tracks and hollows, interpreted by researchers as evidence of repeated gatherings of dinosaurs specifically for reproductive displays. These aren’t simply random wanderings; the consistent pattern suggests a purposeful, communal space used season after season. the tracks indicate large dinosaurs, likely ornithopods, were the participants in these ancient courtship rituals.
This discovery challenges the conventional image of dinosaurs as solitary, aggressive creatures, painting a picture of complex social lives and sophisticated mating strategies. It also highlights the enduring legacy of dinosaur behavior in modern birds.
## What is a ‘Lek’?
The term “lek” originates from the Swedish word for play, and describes an aggregation of males gathered to engage in competitive displays and courtship rituals, with females choosing among them. This behavior is common in many bird species today. Think of the vibrant displays of prairie chickens, the elaborate dances of birds-of-paradise, or the booming calls of sage grouse.
