So the Pipestone Creek bone bed is one of the largest and densest dinosaur deposits in North America, if not the entire world.
For about 90% of the material in this bone bed belongs to one species of dinosaur.
That's a dinosaur called Pachyrhinosaurus.
And these animals died in a mass death event.
So we believe that they were traveling in a herd, potentially a herd of up to 10,000 animals.
And then one terrible day for them, something happened that wiped out, if not this entire herd, then a good portion of it.
And this is where they were buried.
And of course, where they eventually were preserved and fossilized for us to find.
And so it's partly the sheer density of fossils at this site.
So we're looking at something like 100 to 300 bones per square meter at this one site.
But it's also the scale of the bone bed.
The bone bed is about a square kilometer in size.
It's the estimated size.
And so it is really remarkable for its size and its density.
And for also the fact that it preserves a dinosaur found here and nowhere else in the world.
The name actually is Latin.
It means thick-nosed lizard.
And they are ceratopsians or horned dinosaurs.
So related to something like a triceratops, but not quite as big.
The thing that makes pachyrhinosaurs unique is instead of having a horn on their nose, like most ceratopsians do, they have a huge bony protuberance that we call a boss.
