The densest dinosaur bonebed in Canada, on a creek southwest of Grande Prairie: 100 to 300 fossils in every square metre, and nearly 8,000 specimens catalogued out of it so far. They are all one species, a horned dinosaur with a great bony boss instead of a nose horn, and they are every age from babies to old adults, which says this was a herd rather than an accumulation. The likeliest story is a flood that took the whole herd at once. The Philip J. Currie Dinosaur Museum stands nearby and works the bed. LOOK ONLY, and Alberta owns what is in the ground.
Pachyrhinosaurus lakustai, thousands of them · Late Cretaceous, Wapiti Formation, about 73 mya
