What were dinosaur sex organs like? Dinosaur mating behavior?

This is a serious question that begs for answers.

I am someone who notices sex organs right away, and so I noticed very quickly the lack of genitalia on dinosauria. So I assume that dinosaur sex organs were more like birds and reptiles. Which are usually small, though ducks have very long ones and lady ducks have very special sex organs. At least this type of duck:

But is that true?

Maybe dinosaur mating behavior might be a better predicament. I know that the balls of certain primates are much larger as others, and usually the ones that have large sacks are promiscuous. Those that live in harems have smaller packages, because they have access to all females and do not engage in sperm competition.

So before I google it, does anybody know anything about dinosaur reproduction?

Some of the larger animals also tend to have, um, larger equipment. Is this true for dinosaurs? Why (not)?

The cloaca's in a pretty inconvenient spot if you have to line them up, back underneath the base of the tail. Probably the fact that birds are able to fly makes the cloacal kiss a lot easier, because they can use their wings to help get into position.


So yeah, most non avian dinosaurs probably had larger dicks than modern birds, with the exception of ducks probably.

I imagine that theropods had penises shaped like an ostrich's and armored ones were designed like a turtles/armadillos.

Thanks Tyrant for the information.

No surprise for the immature comments here. Some people just do not understand the beauty of reproductive systems which are sex organs. I for one am amazed at the diversity of them.

I do find it disturbing however that Vice seems to ignore female genitalia. Reminds me of following:

Biased biology: the case of the missing vaginas

Genitalia are a hot topic. Interest in their diversity and rapid evolution have seen research in the field balloon in the past decade. Stories on studies of the penises of ostriches, chickens, sea slugs and a variety of insects have all made the science pages. But where are all the female genitalia?

A study published in PLoS Biology this week has quantified their dearth. Analysing 25 years of research in the evolution of genitals, the authors found a strong bias towards studying male animals — a disparity that has got worse over time. The bias, they say, is down to ingrained biases that lead researchers to see female genitalia as less important to evolution — something that, they argue, is hampering our understanding.

Look at this amazing genitalia. Note that this is not an invitation to put vaginas all over this thread. Nor make dirty jokes.
