July 14, 2012: Dinosex (potentially a teensy bit NSFW)

[Ibby]

This one's been making the internet rounds. I pulled these images and the quote below from HuffPo, but I've seen it a handful of other places too. follow a few of the links from their story!

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.

There you have it, folks. Dinos did it doggy.
