And they’ve come up with some surprisingly specific ideas about how the prehistoric beasts were able to mate despite their enormous size and weight–and despite the horns and other bony appendages that might have proven bothersome when the creatures got hot and bothered.
The males and females of modern-day birds and reptiles have a single body opening for urination, defecation, and reproduction–something called a cloaca (Latin for sewer). Paleontologists believe that dinosaurs had the same basic equipment, and that they coupled by pressing their cloacas together.
No penis is needed to perform a “cloacal kiss.” But some birds have penises and crocodiles sport penis-like “intromittent organs,” and male dinosaurs might have had something similar. As you might imagine, a dinosaur penis might have been pretty big–perhaps up to 12 feet in length for T. Rexes.
But how did Mr. Dino ever get his cloaca near Ms. Dino’s? By mounting her from behind. At least that’s the view of many paleontologists, including one Beverly Halstead, an Englishman who became known for his candid talk about dinosaur mating before his death in 1991…
