Dinosaurs Related to T. Rex Possibly Performed a "Moonwalk" to Court Mates, Discovered Fossil Suggests a "Mating Arena"
Discovery of Prehistoric "Dance Floor" Sheds Light on Dinosaur Mating Behavior
A remarkable discovery has been made at Dinosaur Ridge in Colorado, offering a fascinating glimpse into the mating rituals of dinosaurs during the Cretaceous period. Researchers have uncovered a series of fossilized scrapes on sandstone, which they believe to be evidence of a "lek" – a gathering place where male theropod dinosaurs engaged in elaborate courtship displays.
The newly identified scrapes, dated to around 100 million years ago (Cretaceous Cenomanian age), were discovered using high-resolution drone imagery and photogrammetry. A total of 25 new scrapes were identified on two surfaces at the ridge, suggesting that multiple individuals continued to participate in mating display behavior during this period.
The dinosaurs that left these intriguing marks were likely small theropods, relatives of the fearsome T. rex, around the size of a modern-day ostrich. They used their claws to dig into the sand and kicked sand behind them while alternating feet, creating a unique pattern of scrapes.
Some tracks show repeated backward stepping combined with counter-clockwise spins, interpreted as dance-like courtship displays. This behavior is reminiscent of a moonwalk with a spin, offering a captivating image of these ancient creatures vying for the attention of potential mates.
Caldwell Buntin, the study's lead author and a lecturer in Earth science at Old Dominion University in Virginia, expressed his excitement about the discovery. The state of Colorado is known for its dinosaur track sites, with previous studies suggesting that dinosaurs returned to these mating spots over successive breeding seasons.
This latest finding provides the most direct behavioral fossil evidence supporting the notion of complex social and mating behaviors in non-avian dinosaurs. It adds to the growing body of evidence suggesting that dinosaurs, like their avian descendants today, engaged in intricate mating rituals.
The discovery at Dinosaur Ridge offers a rare publicly accessible example of dinosaur behavioral evidence preserved over millions of years. Future research may uncover even more secrets about these fascinating creatures and their ancient world.
