The diverse collection of dinosaur bones at the park, part of the late Cretaceous period, include: ceratopsia, hadrosauridae, ankylosauria, hypsilophodontidae, pachycelphalosauria, tyrannosauridae, ornithomimidae, caenagnathidae, dromaeosauridae, and troodontidae. Previous to 1985, exhibits of these fossils could be found at the Toronto's Royal Agricultural Museum, Ottawa's Canadian Museum of Nature, and the New York City's American Museum of Natural History. Today, the exhibits are displayed at Drumheller's Royal Tyrrell Museum of Palaeontology.
Dinosaur Provincial Park, located only two and a half hours southeast of Calgary, supports three ecosystems: badlands, prairie grasslands and riverside cottonwoods. Current inhabitants are much smaller than the dinosaurs. "Choruses of coyotes are common at dusk as well as calls of nightowls." Daytime visitors can spot cottontail rabbits, mule deer and pronghorns. In the spring and summer, curlews and Canada geese fill the skies.
