A tad gross - But interesting! :)

We know a lot about dinosaurs -- what they looked like, what they ate and what killed them off -- but no fossils have definitively preserved two dinosaurs in the act of mating.​
However, a fossil from China of a Psittacosaurus is so well preserved that the opening the Labrador-size dinosaur used to pee, poop and reproduce is visible, allowing paleontologists to study it for the first time.​
While it doesn't offer any concrete answers on how dinosaurs may have procreated, it does give some hints.​
"We don't have any dinosaur fossils where you can be confident they've been caught in the act," said Jakob Vinther, a paleontologist and senior lecturer at the University of Bristol's School of Earth Sciences.​
What we know is "based on natural history where we compare it to living groups of animals."​
While most mammals have separate holes for bodily functions, many other animals -- including birds and reptiles -- have just one and it's known as the cloaca.​
The fossilized cloaca confirms that dinosaurs had one but it doesn't look like that of any other living animals.​
"It is very unique. Most cloacas form a kind of slit. Sometimes it's a vertical split, sometimes it's a smiley face, sometimes it's a sour face. This thing has a V-shaped structure with a pair of nice flaring lips and there's not a living groups of animals that have morphology like that," Vinther said. "It is somewhat similar to crocodiles but still unique."​
