How Dinosaurs Coupled Up

The video explores the mating behaviors of dinosaurs, drawing comparisons with modern animals like birds and crocodilians. It discusses fossil evidence, particularly scrape marks, as indicators of dinosaur courtship rituals. The video also examines the anatomy of dinosaur cloacas to infer mating practices, suggesting similarities with birds and crocodilians. Overall, it provides insights into the reproductive behaviors of these ancient creatures.
