I attended a zoom meeting the other day about dinosaur sex (in the evening, as opposed to the *daily* lockdown educational dinosaur meetings hosted by Dustin Growick, archived starting here, which are more kid-safe https://www.youtube.com/watch?v=FfRh-nEMRNQ ) Aside from learning that there is dinosaur + people erotica (how does one get consent? Not surprised that one of the authors is Chuck Tingle), it turns out that we don't know anything about dinosaurs doing it except that eggs resulted. Everything else is extrapolated from what current birds do, because birds are dinosaurs, specifically therapods, originating in the Triassic. Except lots of birds can fly. At any rate, most bird sexual reproduction happens from brief cloaca smashing, but some male birds have penises in their cloaca area, an apparently ducks are the weirdest. Duck vaginas are correspondingly weird (still part of the cloaca), and there is sometimes violence involved. Yuck. So we predict that dinosaur sex was also cloaca smashing, but we don't know for sure.
