No one knows for sure how dinosaurs mate. It’s easy to get caught up in a dinosaur’s grotesque features, but have you ever wondered how dinosaurs mated in the first place? With all those spines and armour, how did they do it enough to roam the world before us? So far, no dinosaurs have been found with their reproductive organs intact. Until then, only cross-referencing from existing descendants (birds and reptiles) as well as computer modelling can give us hints as to how they’d done the deed.
