Paleontologists spend a surprising amount of time contemplating dino sex. They have all kinds of theories as to how it went down, but unfortunately, there's no actual flesh to, well, flesh out the details.

Birds and reptiles are dinosaurs' closest living relatives, and because they all have a cloaca — a single opening for urination, defecation, and reproduction — most paleontologists believe that dinosaurs did the deed through such an orifice as well.

This may not have required a penis. Some birds reproduce by squirting semen from one cloaca at another in what modern ornithologists call a "cloacal kiss." Their dino ancestors may have engaged in that rather unsexy form of sex kissing too.

On the other hand, males might have had penises, and very prominent ones at that. From zero to enormous, the ratio of penis length to body size varies drastically among dinosaur descendants, making it next to impossible to speculate on the question of their endowment. Some two-foot-tall ducks, for example, have 7-inch penises, while 15-foot-long crocodiles have mere 4-inch members. A 40-foot-long Tyrannosaurus rex, therefore, may have had a 10-inch penis, or a 12-foot-long one.

Furthermore, according to Brian Palmer at Slate, "Paleontologists can only guess about mating positions, duration, and behavior. The majority view seems to be that large males like the Mamenchisaurus — a 60-foot-long behemoth featured in the new exhibition [at the American Museum of Natural History] — probably mounted from behind, like modern giraffes and elephants."

Very carefully I would have thought?
I question everything. I don't believe anything I'm told or anything I see. Prove it, or fuck off. And that's not me I see in the mirror in the morning.

I believe the dinosaurs would have had sex pretty much like we do presently.

There's dinner, dancing, movies, a terrible waste of expense and time involved, followed by days and weeks of talking, talking, talking....soon followed by the usual and customary trip to meet the parents....who I would imagine would have either eaten the suitor or signed off on them.

Other opinions?

:shock:

:mrgreen:
I would suggest that dinosaur sex was just finding a shallowish pool of water, all the dinosaurs get in it. the males fill the pool with sperm, and the females are impregnated via what can only be horrifically described as submergent cloacal queefing.
