But because now, of course, we study them.

So the rocks themselves indicate that this was an area that was very warm and very wet.

Some of the plant fossils from the region, for example, point to an environment that was almost like a cloud forest, like almost like a rainforest.

So really, really wet, sort of an environment that you would equate to somewhere on the coast today.

The rocks themselves are fluvial deposits.

They're deposits that were formed in rivers.

Also mixed in with the Pachyrhinosaurus, there's these big coalified logs.

So we know that whatever deposited the dinosaurs was carrying big chunks of vegetation with it, similar to what we would expect from a flood today.

We don't understand sexual dimorphism in this animal.

So what makes the males different from the females, or if there is even a feature that does.

We know we have individuals that vary in appearance.

So for example, some have got really big bosses, some have got really small ones, some have got huge long horns on their frills, some have got really little ones.

But in dinosaurs, which laid eggs, there is very little in terms of an osteological signature, basically a signature in the bone that will tell males from females.

So I think because we have such a huge sample size of Pipestone Creek, it's one of our best places to kind of pin down what sexual dimorphism in horned dinosaurs looks like.

Again, that's not something that's well known pretty much anywhere in the world.

Mammals are easy because we give birth to live young, so the females and the males have got different pelvic structures.

Something like dinosaurs and birds actually as well.

Skeletally, males and females are very similar to each other.

Yes, exactly.

So dinosaurs had a cloaca like a bird, like sort of a common opening where sort of everything came out.
