Dinosaur Mating rituals: Largest Lekking Site Discovered at Dinosaur Ridge

A groundbreaking revelation at dinosaur Ridge reveals what may be the largest dinosaur mating site ever found, showcasing elaborate “lekking” behavior from over 100 million years ago. Paleontologists have identified 35 fossilized scrape marks, indicating a bustling arena where dinosaurs performed mating dances to attract partners. This remarkable site offers unprecedented insights into the social lives and reproductive strategies of these prehistoric creatures.

Unearthing the Dinosaur Dance Floor

The term “lekking” describes the complex mating rituals where males display energetic movements to impress females, a behavior still observed in modern birds, descendants of dinosaurs. At Dinosaur Ridge, researchers initially noted five fossilized scrape marks. However, further examination using aerial imagery revealed a total of 35 marks, transforming the former wetland into what appears to be one of the moast extensive mating destinations from the dinosaur age.

Did You know? Lekking behavior isn’t unique to dinosaurs and birds. Several species of mammals, fish, and insects also engage in similar mating displays.

The Meaning of Dinosaur Lekking

Around 100 million years ago, various dinosaur species, including duck-billed hadrosaurs and ostrich-like herbivores, roamed the area, leaving track marks in the soft earth. Researchers found that the dinosaurs marked solid rock on a slope with dynamic traces, suggesting this was the epicenter of their mating rituals. The site, currently closed to foot traffic to preserve the track marks, has been compared to a prehistoric dance club.

Dr. Caldwell Buntin from Old Dominion University, the lead author of the study, explained that Martin Lockley initially identified the trace fossils and determined they were likely related to mating displays after ruling out other behaviors such as nesting or foraging.Buntin’s team used a data-driven approach to validate Lockley’s findings, confirming that these were indeed traces of a mating dance.

High-resolution drone imagery revealed 35 Ostendichnus, the scientific name for the claw marks associated with these mating dances. These findings provide concrete evidence of complex social behaviors among dinosaurs.

Decoding the Dinosaur Dance

buntin suggests that Ornithomimids (ostrich-like herbivores) and Acrocanthosaurus (similar in appearance to a T. rex) both utilized this site for mating. The markings, bowl-shaped and elongated, indicate repeated backward kicking movements, suggesting the dinosaurs turned clockwise and scraped their claws through the sand. The circular markings also hint at possible nesting activities.
